Question Image

The two MAC-VRFs are interconnected through IP-VRF3, which is to be deployed with asymmetric routing.

Which statement is FALSE?

  • A Leaf-1 and Leaf-2 will advertise the IP prefixes to each other using EVPN route-type 5.
  • B Leaf-1 and Leaf-2 must both have instances of MAC-VRF1 and MAC-VRF2.
  • C Leaf-1 and Leaf-2 will advertise host MAC/IP address information using EVPN route-type 2.
  • D MAC-VRF1 and MAC-VRF2 will connect to IP-VRF3 using an IRB interface.
Explanation

Asymmetric IRB in an EVPN-VXLAN fabric uses EVPN Type 2 MAC/IP advertisements for host reachability. The ingress VTEP routes traffic into the destination VLAN/VNI, so each leaf must have the destination MAC-VRF configured; the MAC-VRFs use IRB interfaces to connect to the Layer 3 IP-VRF. EVPN Type 5 IP-prefix routing is used for the symmetric IRB model, not this asymmetric Type 2 design.
