VLC player with Cisco IGMP/Mcast problems

[dvtestguy]

Not able to see my client join the VLC players streams based on the configs/toplogy below.

I'm running an IGMPv3 SSM environment in a 232.255.x.x range. However, the VLC keeps defaulting to 239.255.255.250 on the Vlan 999 that it's playing into.

Topology:
c6506 --- 4503 <--- VLC --- 4948 <--- Client

My experience with getting Multicasting to get TV around a LAN was that I did 3 things:
- On each Layer3 device:
- globally enable multicast routing (needed Enhanced image on 3750 switches)
- per interface enable PIM sparse-dense mode
- On the multimedia server, change the Multicast-Max-Hop-Count upwards from the "0" it was configured to by default.

Not sure I understand your problem though - your VLC is playing onto VLAN 999?
It needs to be multicast-routed over to the VLAN209?
(Why is VLAN 999 "shutdown"?)
Not sure the switch is responsible for the multicast group the clients advertise wanting membership to vs. the address the server is multicasting at ...?

Vince,

The VLC player is playing into Vlan 999 and the Client is on Vlan 209. I took the "shutdown" command off vlan 999.

It's an SSM IGMPv3 environment, so I can't have the client and VLC traffic on the same vlan.

The 6506 is the querying switch and the 4503/4948 are snooping switches.
