Re: Multicast - on IP/TV only voice stream works, while video do
we finally found out what was happening (or at least the explanation appears worthy of belief).
LAN Emulation is our customer's layer 2 protocol.
In a certain moment our customer upgraded the router acting as Rendezvous Point (static RP), at that time IP/TV was running.
LANE creates point-to-multipoint SVC's as needed. It seems that the multicast_group_owner of the video group was that RP router, and when it was reloaded, another router got the ownership. So, when the RP router came online again video packets couldn't find a fine reverse path and were dropped.
Our customer changed IP/TV server configuration and began to send audio and video packets to other multicast groups and it worked fine because newly created SVC's were right.
I believe that in a real broadcast layer 2 framework the problem would not happen. In this LANE environment, it seems better to stop IP/TV server if you are planning to reload RP router.
