Multicast Routing "PIM" cant escape local vlan

Answered Question
Apr 2nd, 2010

Hello

I have a multicast problem and as I understand it I have multicast setup correctly.  Basically I have a multicast server, a VLC server udp multicasting a mp3 file, but the traffic can’t escape the local vlan even though ip pim sparse mode is setup.  The rendezvous point is on the vlan that one of the receivers is on.

I’m lost as to why the traffic can’t escape its own vlan.    Attached is a picture of the layout.

Any help is greatly appreciated.

I have this problem too.

Check that multicast ttl is set to > 1 as it needs to be to go across vlans. You set this within VLC GUI.
