Multicast through vlans issue with 6509 switch

[mohammad saeed]

Hi Guys,

I hope you are fine all :-)

I have an issue with my network. first I introduce my topology:

IPTV Streamer10.60.120.2(vlan121)-----2960s--fiber cable(mode trunk)----6509 core-sw------VLC server(vlan101)

when I check my Streams within the same vlan 121 is OK but can not watch my stream in VLAN101!

About TTL is 5 in my streamer vlc video and I here is my configs in my core switch:

!
interface Vlan121
description "FOR IPTV"
ip address 10.60.120.1 255.255.252.0
ip pim sparse-dense-mode
ip igmp tcn query count 1
hold-queue 2000 in
end

interface Vlan101
ip address 10.60.1.1 255.255.255.0
ip pim sparse-dense-mode
ip igmp join-group 224.1.1.104
ip igmp tcn query count 1
hold-queue 2000 in
end

ip multicast-routing
ip multicast route-limit 3
ip igmp immediate-leave group-list 15
ip igmp snooping tcn query solicit
ip igmp snooping querier address 10.60.120.2
ip igmp snooping querier

and here is the link for streaming inside my centos server: 

su - sysadm -c "cvlc /var/www/html/Movies/test.mp4 --sout '#std{access=udp,mux=ts,dst=224.1.1.104:50000,ttl=5}' --loop &" > /dev/null

Thanks for any help :)

Seems like you are using sparse-dense mode , why such a choice ? 

Do you have candidate RP and napping agent confirgured on your network ? 

If not , you may need to switch to regular sparse mode with static RP, could be simpler ..

When I was using Regular sparse mode I noticed the cpu processing is much higher thats why I am using dense mode!

Hello

How is the 2960 switch configure for MC?

Hi Paul

in 2960 just I have this:

ip igmp snooping vlan 121(IPTV vlan) immediate-leave

[paul driver]

Hello 

at the very least you need to apply a RP address for sparse mode to query then it can fail over to dense mode when no MA is found or change the pim interface to just dense mode

Make sure you have all necessary interfaces enabled for pim

Yes but my point is that you may have misconfigured your sparse-dense-mode .

If there is no RP and MA it will not work

 Can please share your results ?
