Hi, I have Cisco 1921/K9 behind operator’s router. And I want to pass multicast traffic – IPTV - from WAN port to a VLAN. At the bottom is a resumed router configuration. When I execute sh ip igmp snooping mrouter there is no port at the vlan! I’m sure there’s missing something but I don’t know what. Please, can you help this newbbie? Thanks!
