L3 EVPN

Which of the following statements regarding the use of asymmetric routing in an L3 EVPN network is FALSE?

  • A The ingress PE performs both MAC and IP forwarding.
  • B The egress PE performs MAC forwarding only.
  • C EVPN route-type 5 must be supported by the PEs involved.
  • D Each MAC-VRF used in the L3 EVPN network must exist on each PE.
Explanation

Asymmetric L3 EVPN forwarding performs the IP route lookup and destination MAC resolution at the ingress PE, while the egress PE performs only MAC forwarding. Because all tenant subnets must be locally represented, every participating PE needs the relevant MAC-VRFs. EVPN Type 5 IP-prefix routes are not required for the asymmetric IRB model; it can use Type 2 MAC/IP advertisements instead.
