Hi All
I have an issue where multicast from Linux server is not flowing to Client via 6509 VSS.
Linux server 1 and 2 sends multicast traffc to Vlan 300 and I have configured IGMP Static-join in Vlan 350 to fetch the multicast traffic. However I am not seeing traffic flowing to Interfaces configured in Vlan 350 and rather traffic from Linus server 1 and 2 keeps on flowing between each other via VSL links may be due to Multicast traffic nature.
Could you please help me in this if you think there is any issue in configuration. I can see "bad hop count" is increasing in show ip traffic output however i have ip multicast ttl-threshold 255 configured under both vlan interface.
I have shown the configuration below from Cisco VSS
