JN0-649: Enterprise Routing and Switching, Professional (JNCIP-ENT)

A multihomed Ethernet segment requires the same ESI on every leaf interface connected to that segment. EVPN Type 4 Ethernet Segment routes let the multihomed leaf devices discover one another and support designated-forwarder behavior, preventing duplicate BUM forwarding toward the shared segment. Therefore, confirm the ESI matches on the two source links and confirm that Leaf2 has Type 4 routes in bgp.evpn.0. Type 3 routes provide inclusive multicast/BUM distribution but do not establish the Ethernet-segment peer relationship.
