For a customer we currently use L2 and L3 subinterfaces on the same physical link. The L2 subinterfaces are connected to a VPLS routing-instance (multihomed) and the L3 subinterfaces are connected to a VRF routing-instance. The L3 subinterfaces are running VRRP between to MX routers.
In a POC environment we are testing to migrate the VPLS connections to a EVPN configuration. For the L2 connections that is no problem, i can migrate them to a multihoming active-active (LACP) or multihoming active-standby EVPN setup. For the L3 connections i can also migrate them to an active-standby setup with VRRP.
When i want to use the L3 connections in an active-active LACP setup i need to create a new evpn instance and move the L3 config on the subinterface to an IRB and the IRB has to be added to the VRF instance. Below the configuration for this:
set routing-instances TEST-L3 protocols evpn
set routing-instances TEST-L3 instance-type evpn
set routing-instances TEST-L3 vlan-id 500
set routing-instances TEST-L3 routing-interface irb.500
set routing-instances TEST-L3 interface ae1.500
set routing-instances TEST-L3 route-distinguisher 10.130.255.2:5500
set routing-instances TEST-L3 vrf-target target:65400:5500
set interfaces irb unit 500 description "*** TEST-L3 ***"
set interfaces irb unit 500 family inet address 10.32.86.2/23 vrrp-group 3 virtual-address 10.32.86.1
set interfaces irb unit 500 family inet address 10.32.86.2/23 vrrp-group 3 priority 120
set interfaces irb unit 500 family inet address 10.32.86.2/23 vrrp-group 3 accept-data
set interfaces irb unit 500 family inet address 10.32.86.2/23 vrrp-group 3 authentication-type md5
set interfaces irb unit 500 family inet address 10.32.86.2/23 vrrp-group 3 authentication-key <key>
set interfaces ae1 unit 500 description "*** L2 interface ***"
set interfaces ae1 unit 500 encapsulation vlan-bridge
set interfaces ae1 unit 500 vlan-id 500
set routing-instances L3-VRF instance-type vrf
set routing-instances L3-VRF interface irb.500
set routing-instances L3-VRF route-distinguisher 10.130.255.2:10490
set routing-instances L3-VRF vrf-target target:65400:10490
set routing-instances L3-VRF vrf-table-label
In this new setup i need to create an extra EVPN instance for the L3 subinterfaces icm with VRRP. Is this the correct configuration for this setup or is there another solution for this?
kind regards,
