QuestionQ31

L3 EVPN

Which statement about using asymmetric routing in an L3 EVPN network is FALSE?

  • A If a host interface’s has two IP addresses, it must send out two separate EVPN route-type 2 updates for the MAC-VRF.
  • B Each PE must have a full ARP table for all of the hosts in the L3 EVPN network.
  • C All the MAC-VRFs connected to the L3 EVPN network must exist on each PE.
  • D The ingress and egress PE routers will perform both MAC and IP forwarding.
Explanation

Asymmetric IRB has unequal forwarding duties: the ingress PE performs MAC, IP, and MAC lookups to route and bridge the packet, whereas the egress PE performs only a MAC lookup to locally bridge it to the destination. The model also requires routing VTEPs to participate in all tenant subnets and retain host MAC-to-IP/ARP information.
