Data Center Architectures Part 1: A deep dive into BGP unnumbered 

RFC 5549 is becoming increasingly popular in the data center IP fabric ecosystem. Here, in part one of a three-part video series, Juniper’s Arun Ghandi and Michal Styszynski provide a basic overview of BGP Unnumbered, specified in RFC 5549.

You’ll learn

  • Why the IETF standardization community proposed the BGP unnumbered standard specified in RFC 5549

  • Why Juniper is adding additional BGP capabilities into our data center fabrics 

  • The differences between BGP unnumbered and regular eBGP

00:12 IP Fabrics using 3-stage or 5-stage data center architectures are becoming the de-facto standard

00:19 in many Tier 2 cloud providers and telco-clouds.

00:23 Still, the lack of configuration or automation capabilities requires additional effort when

00:29 deploying these highly scalable networks using eBGP.

00:33 And that is why the IETF standardization community proposed the BGP unnumbered standard, specified

00:41 in RFC 5549, which is becoming increasingly popular in Data Center IP Fabric eco-system.

00:49 I'm excited to have Michal join me on the first three-part video series to discuss BGP

00:56 unnumbered.Michal Styszynski, thanks for joining.

00:59 I'd love to hear your thoughts on a few questions I have.

01:09 Juniper already has a decent number of BGP capabilities in Junos and Junos OS Evolved.

01:16 Is there any reason in particular for adding additional BGP capabilities into our data

01:21 center fabrics?

01:23 Outside of tier-1 cloud providers using IP Fabrics extensively with built-in automation

01:41 tools, the native IP Fabrics using qfx5220-32cd are becoming popular also in smaller scale

02:04 Telco-Cloud and Enterprise DC eco-system, so for those environments which are not using

02:10 day one any fabric managers or automation tools, the BGP unnumbered can simplify the

02:44 way IP Fabrics are getting deployed in production networks.

02:51 Is the BGP

03:08 unnumbered easy to enable compared to our IGP - Interior Gateway Protocols?

03:21 As a matter of fact, with the BGP unnumbered, we specify the interface name at the BGP peering

03:44 level instead of specifying the local and remote IP address.

03:52 Add a comment based on a mini demo video of the configuration

04:14 and verification.

04:39 What are the differences between the BGP unnumbered vs. regular eBGP?

04:49 Overall, the main difference is regarding the single hop vs. multi-hop BGP capability

05:12 - we typically use the BGP unnumbered for underlay point to point eBGP peering, and

05:31 on top of it, we can add the multi-hop eBGP for any overlay peering purposes.
