Caveats in Cisco IOS XE 3.10S Releases
Symptom: Layer3 multicast traffic drop is seen on Trunk port.
Conditions: This issue occurs when multicast is converged. Performing a shutdown followed by a
no shutdown on the multicast router interface fails to transmit multicast traffic to TEFP's.
Workaround: Clear IP multicast routes using clear ip mroute command for IPv4 traffic and clear
ipv6 pim topo command for IPv6 traffic.
