Symptom
A nexus 3100 switch running 9.2.2 code is duplicating the initial multicast traffic it sends. If the switch is sent 5000 packets it will duplicate the first and send 5001 onward. This is with an MSDP RP configuration.
With a PIM anycast RP configuration the same switch will create more duplication. It was observed that 5000 were received and 5010 were forwarded.
Conditions
Nexus 3100 switch running 9.2.2 and pim. Being RP may be a requirement.
Workaround
configure (S,G) expiry timeout as a very high value to avoid the duplication and or dropping of multicast when (S,G) is initally being built.
configure terminal
ip pim sg-expiry-timer sg-list
