Multicast Does not work between different VLANS

Hi Jon, now i revert back to dense mode all interfaces.

This is the output for the show ip mroute associate with the multicast stream.

(*, 230.0.0.50), 00:16:21/00:02:43, RP 0.0.0.0, flags: DC

  Incoming interface: Null, RPF nbr 0.0.0.0

  Outgoing interface list:

    Vlan80, Forward/Sparse, 00:16:21/00:02:43

    Vlan254, Forward/Sparse-Dense, 00:16:21/00:00:00

I stop all the VLC receivers on vlan 80 an try to connect again but not work.

Hi

What client are you using? Windows 7 or XP? Check for client firewall issues and client/server mtu issues. What is the output of the show ip mroute active command when the server  is sending the stream?  On the 2960 switches the client is connected to what is the ouput of the show ip igmp snoooping groups?

Multicast Does not work between different VLANS

Hi johnd...

Im using VLC 1.1.2 (i can not update because i have a DVDT2 card to capture the digital terrestrial television and it only work in this version). I have all the firewalls down.

This is the output for the show ip igmp snooping groups on the 2960.

80        230.0.0.50               igmp        v2          Gi1/0/21, Gi1/0/24

Port G1/0/21 is where the receiver is conected and the 24port is the trunk.

Jon, i revert and this is the output. I put the ip pim rp-address the same of the lookpback that i create previously.

(*, 230.0.0.50), 00:37:46/00:02:19, RP 192.168.230.230, flags: SJC

  Incoming interface: Null, RPF nbr 0.0.0.0

  Outgoing interface list:

    Vlan80, Forward/Dense, 00:09:52/00:00:00

The strange thing is that I have more than 40 vlans and it only fail in some vlans like 80.

Okay, lets try and break this down logically.

1) pick a vlan where it does work and use vlan 80 for one that doesn't

2) describe exactly where the source of the stream and the client of the stream are for both scenarios. What i mean by this is which switch is the source/client connected to and how is this switch connected back to the core. So for both scenarios ie. one that works and vlan 80 we need the full path in terms of switches etc. between the source and client.

3) post the L3 SVI configs for source/client vlans from the core switches
