I have a pair of 9ks running as my core in vPC. I'm trying to set up multicast between two SVI interfaces at this location, it does not need to route to other areas/offices/devices on our network. It looks to be set up correctly but I can not get the traffic to go through properly. The multicast sender is an Informacast server on vlan 2 and the receiver is an IP speaker on vlan 3.
At the Informacast server we have done packet captures and it is sending the multicast traffic. But, at the speaker I am not seeing the full data set that I expect. I see an a few IGMPv2 packets that are "Membership Report group" and another IGMPv2 that is "Leave Group" but I do not see the actual packets that I would expect to see.
When I send a message from Informacast, I see the multicast stream show up on the nexus switches with the following commands.
show ip igmp groups
Group Address Type Interface Uptime Expires Last Reporter
239.0.1.2 D Vlan18 00:00:03 00:04:16 10.0.0.20
show ip igmp snooping groups
Vlan Group Address Ver Type Port list
3 239.0.1.2 v2 D Po1
I have the following in my configuration
feature pim
interface vlan2
ip pim sparse-mode
interface vlan3
ip pim sparse-mode
Also added the following to one switch when that didn't work
ip pim rp-address (IP of SVI on vlan 3) group-list 224.0.0.0/4
I actually see on the IP speaker that the multicast stream started and finished 10 seconds later, but I never hear any audio. Is there anything I'm missing or anything on the Nexus that might cause the membership groups to show up in a packet capture but not the actual traffic?
Thank you for any help.
