Dell SmartFabric OS10 User Guide Release 10.5.3

BUM traffic handling

EVPN provides mechanisms in which each PE or VTEP that is destined to receive BUM traffic, advertises an inclusive multicast ethernet tag EVPN route (Type-3) for a given EVPN bridge domain or EVI.

This behavior is accompanied by provider multicast service interface (PMSI) tunnel attribute, which specifies the Tunnel Type (for example, Ingress Replication), Encapsulation type (VXLAN), to be used to forward the traffic to the VTEP or PE, and the routable address of the PE or VTEP.

Dell SmartFabric OS10 supports ingress replication of the BUM traffic to all the remote VTEPs that advertised the inclusive multicast EVPN route in a given EVI.
