Configuring the Network Between the Data Center Core and the Data Center PODs

The steps required to configure network between the data center core and data center PODs are shown in the following section:

• Configure MC-LAG on the VDC POD to the Core
• Configure MC-LAG at Core Switch 1
• Configure MC-LAG at Core Switch 2
• Verify the configuration

1. Configure MC-LAG ae0 between VDC-pod1-sw1 to VDC-core-sw1 and VDC-core-sw2.
   1. Enable the Ethernet bundle on the chassis.

      [edit]set interfaces interface-range MC-LAG-ae0-members member "n0:xe-0/0/[0-11]"set interfaces interface-range MC-LAG-ae0-members member "n1:xe-0/0/[0-11]"set interfaces interface-range MC-LAG-ae0-members description "MC-LAG to Core-sw ae0"set interfaces interface-range MC-LAG-ae0-members ether-options 802.3ad NW-NG-0:ae0

      Note: n0:xe-0/0/[0-11] is connected to VDC-core-sw1 n1:xe-0/0/[0-11] is connected to VDC-core-sw2

2. Configure MC-LAG at VDC-core-sw1 (EX9214-1).
   1. Specify the number of aggregated Ethernet interfaces to be created.
      [edit]set chassis aggregated-devices ethernet device-count 30
   2. Specify the members to be included within the aggregated Ethernet bundle ae0.
      [edit]set interfaces NW-NG-0:ae0 description POD1-to-core-MC-LAG-UPLINKset interfaces NW-NG-0:ae0 aggregated-ether-options minimum-links 1set interfaces NW-NG-0:ae0 aggregated-ether-options link-speed 10gset interfaces NW-NG-0:ae0 aggregated-ether-options lacp activeset interfaces NW-NG-0:ae0 unit 0 family ethernet-switching port-mode trunk
   3. Configure LACP parameters with static system-id and admin-key on the aggregated Ethernet bundle.
      [edit]set interfaces ae0 description "MC-LAG to VDC-pod1-sw1-nng-ae0"set interfaces ae0 aggregated-ether-options lacp activeset interfaces ae0 aggregated-ether-options lacp system-priority 100set interfaces ae0 aggregated-ether-options lacp system-id 00:00:00:00:00:01set interfaces ae0 aggregated-ether-options lacp admin-key 1
   4. Configure MC-AE interface parameters.
      [edit]set interfaces ae0 aggregated-ether-options mc-ae mc-ae-id 1set interfaces ae0 aggregated-ether-options mc-ae redundancy-group 1set interfaces ae0 aggregated-ether-options mc-ae chassis-id 0set interfaces ae0 aggregated-ether-options mc-ae mode active-activeset interfaces ae0 aggregated-ether-options mc-ae status-control activeset interfaces ae0 aggregated-ether-options mc-ae init-delay-time 520set interfaces ae0 aggregated-ether-options mc-ae events iccp-peer-down force-icl-downset interfaces ae0 aggregated-ether-options mc-ae events iccp-peer-down prefer-status-control-activeset interfaces ae0 unit 0 multi-chassis-protection 192.168.168.5 interface ae9.0

      Note: Please review the following caveats and guidelines: The multi-chassis aggregated Ethernet identification number (mc-ae-id) specifies the link aggregation group to which the aggregated Ethernet interface belongs. The ae0 interfaces on VDC-core-sw1 and VDC-core-sw2 are configured with mc-ae-id 1. The ae1 interfaces on VDC-core-sw1 and VDC-core-sw2 are configured with mc-ae-id 2. The redundancy-group 1 statement is used by ICCP to associate multiple chassis that perform similar redundancy functions and to establish a communication channel so that applications on peering chassis can send messages to each other. The ae0 and ae1 interfaces on VDC-core-sw1 and VDC-core-sw2 are configured with the same redundancy group redundancy-group 1. The chassis-id statement is used by LACP for calculating the port number of the MC-LAG's physical member links. VDC-core-sw1 uses chassid-id 0 to identify both its ae0 and ae1 interfaces. VDC-core-sw2uses chassis-id 1 to identify both its ae0 and ae1 and other interfaces. The mode statement indicates whether an MC-LAG is in active-standby mode or active-active mode. Chassis that are in the same group must be in the same mode. Here we have configured active-active. Status-control must be active on one PE and standby on the other node. mc-ae events iccp-peer-down prefer-status-control-active is needed to pre-configure the active node during ICCP failover scenarios. By default one device will be active and other node will be standby To get better convergence on node reboot scenarios, both nodes can be configured as prefer-status-control-active. We have to make sure that the ICCP session goes down due to physical link failures by configuring ICCP peering with the loopback address. mc-ae init-delay-time is configured to be a higher value, which delays the start-up of the MC-AE links during device recovery. This allows the protocol convergence to complete and be ready to forward packets coming from MC-AE to the core-switch.

   5. Configure allowed VLANS on this MC-LAG link.
      [edit]set interfaces ae0 unit 0 family ethernet-switching interface-mode trunkset interfaces ae0 unit 0 family ethernet-switching vlan members MGMTset interfaces ae0 unit 0 family ethernet-switching vlan members Infraset interfaces ae0 unit 0 family ethernet-switching vlan members Tera-VMset interfaces ae0 unit 0 family ethernet-switching vlan members Security-Mgmtset interfaces ae0 unit 0 family ethernet-switching vlan members Vmotionset interfaces ae0 unit 0 family ethernet-switching vlan members VM-FTset interfaces ae0 unit 0 family ethernet-switching vlan members Remote-Accessset interfaces ae0 unit 0 family ethernet-switching vlan members POD1-Transport-1

   13. Configure the switch service-id for MC-LAG.
       [edit]set switch-options service-id 1

       Note: You must configure the same unique network-wide configuration for a service in the set of PE routers providing the service. This service ID is required if the multi-chassis aggregated Ethernet interfaces are part of a bridge domain.
