IPTV multicast between VLANs

Hi Guys,

 

I have this topology for IPTV stream,

 

Streamer GW >>>>>2960s switch>>>>Core sw6807XL>>>>2960s Switch>>>>VLC

 

Streamer in VLAN 181:

description ##IPTV STREAMER##
ip address 172.16.10.1 255.255.254.0
ip pim dense-mode

 

VLC in VLAN 102:

 

ip address 10.63.3.1 255.255.255.0
ip pim dense-mode

 

in core sw there is IP multicast routing enabled

ip multicast-routing
ip igmp snooping tcn query solicit

 

the streaming is working in the same vlan but not with different vlan!

 

The TTL in streamer is 2

 

Any Idea about my issue?

 

Thanks

Hello,

 

the configuration looks by the book. TTL is usually one of the things to look at, but since it is set to 2, that should be okay as well.

 

There are a couple of debug commands, you might want to turn debugging on, and post the output here, maybe we can spot something:

 

debug ip igmp
debug ip mpacket
debug ip mrouting
debug ip pim

Hello,

 

with pim dense, it should not be necessary, but what if you add:

 

ip igmp join-group 224.1.1.114

 

to both Vlan interfaces ?

Hello,

 

I don't know what the default ttl threshold is on the 6870 switch, but try and set it manually on the Vlan interfaces:

 

ip multicast ttl-threshold 15

After deep looking the network and investigating I found the client uses one streamer from another 2960 switch and he wants to add another Linux centos streamer from and both streamers on Samel VLAN 181.

 

the first stream is working from VLAN 181 but the new one from VLAN 181 not working!

 

Can two streamers from same VLAN stream at the same time between different VLANs?
