Description (partial)

Traffic loss with multicast ingress bridging traffic.

This happens when both multicast ingress bridging and routed traffic egress to the same port. The L2 ingress bridging copy will be dropped and all routed copies will be forwarded. For example, if traffic comes in from port e1/1 and needs to be both bridged to L2 receivers and routed to L3 receivers on port e1/2 (trunk port) then the bridged traffic will be dropped.
