Underlay Multicast Routing for VxLAN BUM Traffic

Leave a Comment /

Belete Ageze – 2xCCIE | CCDE Overview While Cisco VxLAN leverages BGP EVPN for the control plane, it requires mechanisms to manage Broadcast, Unknown Unicast, and Multicast (BUM) traffic within the VxLAN fabric. VxLAN fabrics typically rely on multicast replication in the underlay network to efficiently forward BUM traffic. Although ingress replication serves as an
