In the Centralized Anycast Gateway configuration, the Spines are configured with EVPN IRB and are used as the IP

Starting with EOS release 4.22.0F, the EVPN VXLAN L3 Gateway using EVPN IRB supports routing traffic from one IPV6

In certain VXLAN deployments with either NSX/Logical Router or EVPN IRB, active nodes hosting a virtual IP address
