Question Image

The network uses interface-less symmetric routing, with ECMP of 4 enabled on every leaf router.

Which of the following statements is FALSE?

  • A Anycast gateway is an optional configuration on the Leaf1 and Leaf2 IRB interfaces.
  • B The IRB interfaces on Leaf1 and Leaf2 must be configured to advertise learned local host-routes.
  • C MAC-VRF100 on Leaf1 and Leaf2 must have BGP EVPN and BGP VPN configured.
  • D IP-VRF1 on Leaf1, Leaf2 and Leaf3 must be configured with a VXLAN-routed interface.
Explanation

In an EVPN Layer 3 deployment where a bridged domain is distributed across multiple leaf nodes, the host-facing IRB interfaces must use the same anycast gateway IP and MAC address. This lets hosts use one default gateway and ensures traffic received by either Leaf1 or Leaf2 can be routed locally. Consequently, the anycast gateway is not optional on those IRB interfaces.
