0:08 we're going to talk about experience the

0:11 campus of the future

0:13 the theme of the today's

0:14 you know session has been continuously

0:16 the full stack the full stack isn't

0:18 complete without our foray

0:19 uh into wired assurance especially going

0:22 into the ai driven uh campuses of the

0:24 future

0:26 the

0:27 just a quick rehash of what we've done

0:29 with wired assurance all all along

0:32 people all of our customers love the way

0:34 missed ap is operated

0:37 you plug in they start beaconing their

0:38 ssid 17 seconds later

0:41 we did the exact same thing going into

0:43 the world of the wired switches as well

0:45 we started the adoption where the claim

0:47 codes uh we started adoption of of

0:49 switches they were using ztp through

0:52 uh zero touch provisioning uh

0:54 and getting to deploy them at scale as

0:56 well we do very well

0:58 with all uh all pieces of anything that

1:01 needs to do with deployment at scale be

1:03 it you know multiple sites across with a

1:06 small branch solution or even a lot

1:08 larger large campus at the deployments

1:11 of the wireless world we brought the

1:13 same thing to the uh wired world too so

1:15 deployment using templatization

1:17 automation uh with with uh with a lot

1:20 more in terms of how can we identify

1:22 devices that come on to your network and

1:25 automatically give them port profiles

1:27 obviously our mainstay for all things

1:29 they do um has always been our ability

1:32 to alert monitor and troubleshoot easily

1:35 so bringing in an automation in to all

1:38 these three pieces was was the key

1:40 pillar for wired assurance as as a as a

1:43 portfolio

1:44 so we spoke about zero touch

1:46 provisioning

1:47 we use the concept of claim codes you

1:50 can claim your switches or you can

1:52 activate thousands of switches all at

1:53 once

1:54 uh and adopt them uh we we speak about

1:57 templatization uh we we speak about

2:00 uh how you can scale how you can

2:03 configure devices at scale and also use

2:06 automation in that fact as well so a

2:08 quick uh refresher on uh what we do with

2:10 dynamic port profiles in in this

2:12 particular example

2:14 there are various kinds of devices that

2:16 come onto your network uh especially

2:17 access switches

2:19 and all of them usually are in bulk you

2:22 provide your access points you provide

2:23 your cameras you provide any of your

2:25 hvac sensors other iot devices

2:28 all configurations across all these

2:29 devices are are usually the same

2:32 on on these interfaces so you let now

2:34 we've brought in the power of dynamic

2:36 port profiles where you say let the

2:38 device

2:39 identify itself as a persona and we'll

2:41 configure it automatically without

2:43 the admin having to go in press a button

2:46 every single time a device comes in to

2:48 say your vlan 2 your speed is 100

2:51 not none of that anymore we can

2:53 automatically detect what device it is

2:55 and we can place them on the profiles

2:58 last piece of it is the wired experience

3:01 on the on the network

3:03 how are you able to down the devices

3:05 that connect on the network how are we

3:06 able to measure stuff

3:08 reid went through a powerful example of

3:11 marvis uh and going through the

3:14 explanation of the wireless was great

3:16 the wired was great and then the van

3:19 where

3:20 was actually the problem how do we come

3:22 to these conclusions on you know uh the

3:25 wireless experience was okay or the

3:26 wired experience was okay is because of

3:28 the amount of telemetry we are able to

3:30 collect

3:31 and provide

3:32 uh these inputs to marvis again

3:35 all of

3:36 all three pieces wired wireless and van

3:39 all all going back to the same ai engine

3:41 and and for that data is key and we

3:43 provide uh these these kind of uh data

3:46 is in into informing these intelligent

3:49 expectations

3:51 so i'll dwell down quickly for a couple

3:53 of more minutes on you know what are the

3:55 advantages of our wired assurance as a

3:57 whole i'll given a few examples of you

4:00 know experiences as a whole

4:02 one of our customers moved from one of

4:05 their radius servers uh to a brand new

4:07 uh radius a different radius server and

4:10 they they are a customer who has over

4:12 1500 sites

4:14 and

4:15 they they just moved uh as a cut over

4:18 from one radio server to the other now

4:21 the sle framework at an org level was

4:24 able to pinpoint exactly the two sides

4:27 on which those those uh new radius

4:29 servers weren't had uh the switches on

4:32 the radio servers weren't added as nas

4:34 clients to exactly say your thousand

4:37 four hundred and ninety eight sites are

4:38 good these two sites are where you where

4:40 it need attention and that's the power

4:42 of bringing in data and also

4:45 condensing them to a point where you can

4:46 consume them easily

4:48 air driven operations we talk about bad

4:50 cables we talk about mtu mismatches

4:52 bring them across you know uh thousands

4:55 of ports uh for example juniper networks

4:58 or

4:58 has about sixty thousand ports we when

5:01 we enabled our assurance on uh we were

5:04 able to bring about exactly 45 parts

5:06 across you know 17 different sites 50

5:10 000 ports to say these are your 45 bad

5:12 cables in there and those those are kind

5:14 of the

5:16 actions that we can provide as an

5:18 administrator so that you know you can

5:20 focus on more things that could be

5:21 productive

5:23 like all things uh

5:25 miss

5:27 every single configuration every single

5:30 stack that we get it's all available in

5:32 automation we have 100 apis and also

5:36 we can you can also work with web hook

5:38 and web sockets for for you to gather

5:40 more information

5:41 in a realistic way if you are consuming

5:43 that way

5:45 best part of it again full stack

5:47 portfolio uh there's one ai engine

5:49 consuming data from wireless wired and

5:51 van so your troubleshooting experiences

5:54 are superior

5:55 let's let's focus on what we want to

5:57 talk about today for especially the

5:59 campus fabric architectures

6:02 we cannot claim that we are a full stack

6:04 solution without us being

6:07 having the ability to

6:10 actually uh talk about campuses and how

6:13 what is our foray

6:15 the the most important uh the the advent

6:19 of evp and vxlan in into the campus is

6:22 recent but also the technology uh by

6:25 itself for the campus administrators are

6:27 new

6:28 it it brings in a level of complexity uh

6:31 where in when you will have to configure

6:34 uh devices and also troubleshoot them

6:36 and that that's a new

6:38 dimension campus administrators have are

6:40 having to deal with

6:41 now everybody wants to move towards

6:44 evpnbxlam because obviously it brings in

6:46 huge amount of benefits for you

6:49 now how do we foray uh into these

6:52 different architectures of juniper as a

6:54 whole we uh we've come out with these

6:56 three architectures and i'll just

6:59 quickly brief through as to what's

7:00 important why we've gone through this

7:03 approach of defining specific

7:05 architectures obviously

7:07 campuses are not one size fits all

7:10 we or we can easily make uh and add

7:12 additions in here but these three are

7:15 guiding uh patterns for you to say which

7:17 would uh fit the bill for a particular

7:20 campus

7:21 the first on your left uh we're talking

7:23 about the evpn multi-homing as we call

7:26 it

7:27 the green blob up there defines where

7:30 the fabric extends across so in in that

7:32 case it's just the collapse code these

7:35 are fit for the smaller architects

7:36 smaller medium architectures your

7:38 distribution device will participate as

7:40 a part of uh you know your access

7:42 devices will still be accessed

7:44 it could be juniper it could be outside

7:47 you can continue to use your existing

7:49 infrastructure at the access and then

7:50 still migrate into

7:52 [Music]

7:53 into fabric by multi-homing your devices

7:56 and creating what we call as uh esi lags

7:59 or ethernet segment identifier

8:01 uh lag interfaces and

8:04 those are best suited for smaller

8:06 architectures or even if you're making

8:07 your 4a uh into

8:09 the world of fabric with minimal changes

8:12 only at your collapse score at that

8:14 point in time

8:16 the second one is uh our campus fabric

8:19 core distribution as the name defines uh

8:22 you can actually

8:23 do the exact same thing if you have a

8:25 larger architecture

8:26 you can still have your axes switching

8:28 outside the fabric they can remain as is

8:31 without any changes to them

8:33 because that's where most amount of

8:34 config changes go into if you prefer uh

8:36 to leave it that way you definitely can

8:39 and still extend your fabric between

8:40 core and your distribution

8:42 and that brings in uh the additional uh

8:45 ease uh to which you you can deploy this

8:48 without actually having to touch

8:50 the most populated part of your

8:51 environment which is the access

8:52 switching

8:54 the right most and the most important

8:56 one i guess which is which is new for us

8:59 which is new for the industry as well as

9:01 we go along is the ability for us to

9:04 stretch fabrics all the way down to the

9:06 axis

9:07 what that brings in is the unique

9:09 advantage of you having uh the ability

9:11 to not only get out at the access but

9:14 also

9:15 uh

9:16 you get all the advantages of evpn vxlan

9:19 uh there's a ton of

9:21 things that we'll also talk about in in

9:23 the next slide but

9:24 one additional advantage that brings in

9:26 is the ability for you

9:29 to actually have security policies

9:32 defined all the way at the edge and try

9:34 and drop traffic closer to the source uh

9:37 it's a unique ability for you to make

9:39 um

9:40 decisions of

9:42 security policy implementation at a

9:44 centralized place like the miss cloud

9:47 and actually have

9:48 security uh

9:50 policy enforced all the way at the edge

9:52 uh the concept constructs of it is

9:54 group-based policy we'll definitely have

9:57 time for it for us to talk about it in

9:59 the in our next uh field day uh but it's

10:02 a unique uh advantage it brings in here

10:05 for today's

10:06 uh session we'll focus on the rightmost

10:09 architecture which is ip clause and

10:11 for one we'll talk about the deployment

10:14 and also talk about what you can do post

10:16 deployment as well

10:18 as a part of the demonstration

10:20 so

10:21 i've already spoken to uh the problem

10:23 statement uh you know you need to uh

10:25 there's a need for stretching mobility

10:27 across you wants a step you want a

10:29 standard space fabric

10:31 which work on evpn vxlan and you would

10:34 like to have multi-homing uh involved as

10:36 well

10:38 what have we done what is miss bringing

10:40 in to actually

10:42 make deployment simple

10:45 in true my style like all things missed

10:48 we went in to the uh we went in with

10:51 actually understanding what the

10:52 administrator is trying to do and how

10:55 what

10:56 and how can we achieve this without

10:58 actually involving all the complexity

11:00 that comes through with the adoption of

11:02 the new technology

11:03 so we we said what what if we already

11:06 have defined the three different

11:07 architectures we said where do you want

11:09 your fabric to be extended so choose one

11:13 we've kind of demonstrated in in prior

11:15 field days we've demonstrated the

11:16 multi-homing as well as the evpn

11:19 um

11:20 ip clause

11:22 the core distribution the topologies

11:24 this one will focus on ip class so you

11:27 you choose the uh topology of your

11:29 choice

11:30 then tell us where your devices reside

11:33 on who which which devices

11:36 are core devices which devices are

11:37 distribution which are access devices

11:41 one thing we will not be able to

11:42 identify is how are they connected

11:44 physically uh if the boxes are still uh

11:47 if the devices are still not uh unpacked

11:50 uh we'll talk about how you uniquely its

11:52 advantage is that you can actually do

11:54 do all of this even without uh

11:58 you can deploy the entire uh network

12:00 even without you having to unbox any of

12:02 your devices as long as you you have the

12:04 activation code with you

12:06 and then you tell us what your networks

12:08 of interest are

12:09 what are your kind of devices that come

12:11 in into the network

12:13 the the most critical piece of it here

12:15 is when we were talking to one of our

12:17 customers

12:19 you know a healthcare customer

12:21 they were talking about the explosion of

12:23 the number of devices that are coming

12:25 into their network and the need for

12:27 segmentation

12:30 how they have to break them uh into vrs

12:33 and that's another advantage you will

12:34 see how you can just define the vlans

12:36 and also if you want to separate them

12:37 into routing tables of their own will

12:39 give you the option to do so but that's

12:42 pretty much it you define the networks

12:44 of your interests and then uh

12:46 and tell us what your physical

12:48 connections are

12:49 and then we'll apply the intent for you

12:51 and

12:53 that would be

12:55 time for us to go into a quick demo

12:58 my name is rohan and

13:01 thank you for passing over

13:03 the demo here

13:05 so here we see um

13:07 obvious spoke about how

13:10 you know easy it is to

13:12 to build the ip class and you all may be

13:14 wondering is it really that easy well it

13:16 is let me let me walk you through what

13:18 we see as we walk into uh the evpn

13:21 configuration here so here you see uh

13:23 there are three different topology types

13:25 for you to choose uh

13:26 you know already spoken about all three

13:28 of them

13:30 well today our focus is campus fabric ip

13:32 class with l3 at the edge

13:35 um

13:36 so so we select one of these topologies

13:38 and you know just give it a name

13:40 and what do we do next we select our as

13:43 numbers

13:44 we select our overlay as we select our

13:46 underlay ais

13:47 here you see

13:49 eventually we can do two byte we can

13:51 also do four byte asn

13:53 no restrictions on that

13:55 uh select your loopback prefix and then

13:57 select your subnet what's the subnet

13:59 really well the subnet is basically uh

14:02 we take care of of the fabric

14:03 connectivity uh you don't have to worry

14:05 about any of those things um you know

14:08 you have you have a three layer topology

14:11 core

14:12 distribution axis

14:14 you don't have to worry about the

14:16 subnetting any of those and we take care

14:18 of all of those things

14:20 so

14:21 um

14:23 moving on

14:26 uh this is this is where you select your

14:28 evpn nodes the

14:31 device is participating in the fabric

14:33 really right

14:34 so select your core devices here

14:38 distribution access

14:42 you have all the information at your

14:44 tips right ready readily available

14:46 um

14:48 if you eventually want to add more

14:50 devices you know you build the topology

14:52 you want to come back and add more

14:54 devices you can expand scale

14:56 click on more switches you'll have more

14:58 switches show up here in your inventory

15:00 and

15:01 you you'll be able to you know add more

15:03 switches to that

15:04 um

15:08 moving on

15:13 um on this page you'll basically be

15:15 configuring your networks and how are

15:18 you going to segment your networks up he

15:20 already spoke about

15:22 uh you know network segmentation

15:24 so basically on this screen you'll be

15:26 selecting your networks uh you can

15:27 create a new network here um you know

15:30 give it a name give the vlan id uh you

15:32 can also you don't have to have a routed

15:35 network in your fabric we also allow you

15:36 to do bridged overlay where you can have

15:39 your gateway on a van device or a

15:42 firewall right uh and you don't have to

15:44 create a network here you can also add

15:46 an existing network let's say you did uh

15:48 you know added add a network uh outside

15:51 of the fabric you wanna import it here

15:53 you can do that uh

15:54 one important feature here that i'd like

15:57 to show you here is you don't even have

15:58 to worry about selecting your ip

16:00 addressing for your for your irb

16:03 svi we take care of all of that stuff

16:05 right you can but if you don't like the

16:07 ips for whatever reason you want to you

16:09 want to change it you can you can go and

16:11 you can you you can statically change

16:13 those ips if you want and then after you

16:14 already spoke about vrf segmentation

16:17 uh you can you know enable your vrf

16:20 share segment uh the vlans per per vrf

16:25 moving on to the next uh page um here uh

16:29 this is the this is the page where

16:30 you'll be basically selecting your ports

16:32 so

16:33 you selected five devices in the network

16:35 you have two cores one distribution to

16:37 access

16:38 all you have to do is just click on

16:39 these devices and click on these ports

16:42 and basically go in and configure your

16:44 ports uh you just want to say hey this

16:46 is my my ge port or it's a it's a a

16:49 multi-gig board

16:50 and

16:52 it's very intuitive uh it's going to ask

16:55 you for for for the number of ports that

16:57 you want and and you can select it

16:59 accordingly right and you can always

17:01 come back and you can edit your ports

17:03 and you can you can change it the way

17:04 you want it to be right

17:06 um so it's as simple as that that's it

17:09 right uh

17:11 moving on we continue this is the final

17:13 view of the topology i can i can click

17:16 here i can see

17:17 this is how my my topology looks like

17:20 this is how i want it do i want to go

17:22 and push the configuration yes i do no i

17:25 don't want to i can go back and make

17:26 changes but in this case we're good

17:28 everything looks good to me we'll go and

17:30 we'll click apply changes and boom

17:33 that's it that's how easy it is to

17:35 config configure your your fabric right

17:38 so um at this point uh we did this exact

17:41 same demo uh when we did uh our previous

17:45 field day uh we said you know you can

17:46 configure your multi-homing in two steps

17:48 all the administrator input was you

17:50 created your vlans you told us how the

17:52 network was connected we we actually

17:55 solved this problem for you

17:57 but uh we we got a response on twitter

18:01 from one of the uh uh from twitter

18:04 saying that's great you you actually uh

18:06 created the fabric in four steps now

18:08 i'll spend 40 hours troubleshooting it

18:11 we took the point he said visibility is

18:14 key what should we do next uh i know

18:17 field day loves live demos i'm gonna go

18:19 ahead and click the next one what should

18:21 we do next how do we

18:23 bring to table

18:25 to make sure troubleshooting is simple

18:27 now

18:28 do i dump all of your show vgp somebody

18:30 and give you a plethora of information

18:33 on click or can i tell you where your

18:36 issues exactly are

18:38 and you can go address that and that's

18:40 where we wanted to bring in the aspect

18:42 of okay what did we give

18:44 the user to actually fiddle with uh the

18:47 most important piece was actually the

18:49 physical connections the rest of it is

18:51 all automated there is very little that

18:53 can go wrong in terms of you uh

18:57 you know configuring the wrong pni or

18:59 configuring the wrong esi id no no those

19:02 things cannot go wrong because all of it

19:03 is automated we've given the control for

19:07 humans for us to say uh go configure the

19:10 ports if there is an error we catch that

19:12 and we bring it to you so if you hover

19:14 over uh rohan uh you will see you know

19:16 uh on the device uh that

19:20 yeah if you you will see that bgp they

19:22 are neighbor

19:24 yeah state is uh is down uh

19:27 and it's also saying that the core two

19:29 is down as well obviously peering is

19:31 down on both ends what is the reason for

19:34 peering being down so let's hover over

19:35 the red line

19:36 the one thing that we gave for us to

19:39 actually uh

19:40 change for us to actually configure was

19:43 the ports and then after telling you

19:45 that whatever port you selected is not

19:47 the port that's a part of the topology

19:49 so let's go ahead and quickly fix this

19:51 uh and then we can come back uh and and

19:53 see how uh how it reflects after and

19:56 also we'll show you a couple more things

19:58 uh in there so let's go ahead right so

20:00 so now that we've seen the problem let's

20:02 go and fix the problem right

20:04 same steps go back

20:06 change the ports

20:07 uh so what was the problem the problem

20:09 was that this is a multi-gig switch

20:13 i i selected a ge port i should have

20:14 selected an mge port

20:18 i'll go and fix that

20:20 that's it

20:22 we make the change apply changes

20:24 confirm

20:26 and while the changes take place now

20:28 while our our bgp tries to come up uh

20:31 let us

20:32 actually walk in and talk about uh an

20:35 important feature here

20:36 uh called uh the connection table right

20:40 um so uh

20:42 yeah this is our topology actually looks

20:44 like uh we didn't go over it but uh

20:48 let's talk about the connection table so

20:49 what's the connection table really so so

20:52 one thing that abby mentioned initially

20:54 was you don't even have to wait for

20:55 these devices to be shipped to you

20:58 you can have the claim codes ready

21:01 once you order these devices you have

21:02 the claim codes you can just go in and

21:04 order uh you know

21:06 down put these claim floats in the in

21:07 the in the system and a device will be

21:10 populated for you and you can build the

21:11 topology so you don't have to really

21:13 wait for the physical devices to be

21:15 stacked so you can build the topology

21:18 download the connection table hand it

21:20 over to your installers and say hey this

21:22 is how the topology needs to be

21:23 connected uh the these this is my mac

21:26 address

21:27 and you you can you can hide all the you

21:29 can hide the the columns you don't want

21:32 you can just say my distribution needs

21:33 to be connected to my core devices like

21:35 this and access the way it is and um

21:39 you know you have the models here

21:41 you have uh the the models for the other

21:44 switches as well here uh it's as simple

21:46 as that uh

21:48 just uh an important uh feature as to uh

21:52 you know

21:53 how

21:55 you can try to fix things that could go

21:57 wrong so so we've taken care of that as

21:59 well

22:00 i mean uh the end goal is you know you

22:02 you put in the hard work to build it you

22:04 don't have to again redraw everything

22:05 well or you hand it over to the low

22:07 voltage guys

22:08 put this excel in front of them and

22:10 hopefully this could be useful for them

22:11 as well in building without errors there

22:14 let's go back into the other piece as

22:16 well

22:17 the other thing uh that we also did uh

22:19 if you go to the access switches yeah

22:21 yeah i'll talk about uh this the

22:24 important uh other important features

22:26 there that we have now uh so you see so

22:29 you go to any device and you click on

22:31 any device you switch insights and

22:33 you'll see

22:34 you'll see the remote shell so

22:37 basically

22:38 we have the remote shell for you

22:39 anything uh if you want to log into the

22:41 device for anything uh as much as we

22:43 would like for you to not do i know all

22:46 of us are uh cli junkies all the way

22:48 inside yeah if you'd like to see it uh

22:50 it's there you can remotely from

22:52 wherever you are in the world yeah you

22:54 can just log in and you can you know run

22:55 any commands you want and you can see if

22:57 your your things are working the way you

22:59 would want or not right

23:01 um uh that is that is a remote shell new

23:04 and improved uh look at switch insights

23:06 so what switch insights really so switch

23:08 insights is basically this is a general

23:11 wide assurance feature um not specific

23:15 to evpn as such and and literally it

23:17 will tell you what's going on with the

23:18 network hey my radio server is only

23:22 my cpu is this my memory is this my it

23:25 is literally doing uh the job of a

23:28 network monitoring tool at this point

23:30 right um

23:32 let's jump to uh access to here right or

23:36 actually i'm going to jump to

23:38 code 2 here

23:40 and look what do we see here my bgp is

23:42 back up i can see in my in my switch

23:45 event so you have everything at your

23:47 tips you don't even have to go back into

23:49 log into the device to check that we'll

23:51 show that to you right

23:53 um

23:54 and and then similarly uh that can go on

23:56 with any other switch as well uh

23:59 of course that is up here as well so

24:01 um

24:05 yeah

24:08 right so let's go back into evpn

24:11 and

24:13 our our topology is fixed our bgp is up

24:17 our network uh

24:20 connectivity is restored

24:21 and and we'll tell you that all of this

24:23 at your fingertips

24:25 you can also look the rx in dx bytes

24:27 what exactly is it it's telling you the

24:29 amount of traffic that's flowing over

24:30 that link and uh

24:32 yeah i think um

24:34 a video won't add anything to that i

24:36 mean yeah at the end of the day the goal

24:38 was for the demo was uh one i know

24:40 techfield likes live demos we wanted to

24:42 make sure we do a live demo uh the

24:44 second piece of it is it's not only easy

24:47 to configure fabrics now it's also easy

24:49 to troubleshoot and pinpoint areas of

24:51 where the trouble is and and make sure

24:54 uh you get them addressed and

24:56 wide assurance is progressing at rapid

24:58 pace and this is our four into the

25:00 campus and that's it thank you thank you
