You have an EVI implemented between PE-1, PE-2, and PE-3 to allow communication between CE-1 and CE-2. CE-2 receives unicast traffic from CE-1 on both links to PE-2 and PE-3. When CE-1 sends broadcast traffic. CE-2 receives it on only one of the multihomed links.
Referring to the exhibit, which EVPN route type enables this behavior?
EVPN (Ethernet VPN) employs different route types for various functions within the network. In this scenario, CE-2 receives unicast traffic from CE-1 on both links to PE-2 and PE-3 but receives broadcast traffic on only one link, demonstrating the behavior of designated forwarder election to prevent duplicate broadcast, unknown unicast, or multicast (BUM) traffic. This behavior corresponds to EVPN route type 4, which is specifically used to elect the designated forwarder in multihomed scenarios. Hence, the correct option is type 4.
B is correct. EVPN route type-4 is used for electing designated forwarder
