Broadcast a single IPTV source on multiple VLAN

[Thomas Cygne]

Hi!

Today I have 8 IPTV streamer each one connected to a VLAN (switch 2960-x)  with IGMP snooping enabled. Most of these streamers have the same configuration: same channel on the same multicast address.

To simplify my network and increase the number of VLAN with IPTV streams, I would like to configure each IPTV streamer with a single channel map. Then I want to be abloe to broadcast each streamer on non or several VLAN.

Example:

- Streamer 1 broadcast on VLAN 10 20 30 and 40

- Streamer 2 broadcast on VLAN 50 and 60

- Streamer 3 broadcast on VLAN 70

- Streamer 3 not broadcasted

- ...

But I'm not sure of the device that I have tu plug between my streamer and my switch. Which protocol will resolve my problem? PIM-SM?

Thanks for your help and recommandation!

Best regards.

First thing first, which vlan your streamers are located ? if they are on different VLAN's then you will need multicat routing in the first place which means a routed network. 2960 are layer 2 switch and can't do Multicast routing AFAIK. After that you can run PIM-SM on all the vlan interfaces and statically define the RP.

Hi Hitesh,

Thanks for the response.

Indeed, because I want that a single streamer broadcast on several Vlan, I will have to setup multicast routing.

However on all guide that i've found, there is at least 2 router (for example: http://www.cisco.com/c/en/us/support/docs/ip/ip-multicast/9356-48.html).

Is it possible to have a single router performing multicast routing and directly connected directly to my different Vlan (on a single switch)?

Sorry if it is a dummy question, it's the first time I use multicast routing with PIM.

Thanks again!

Yes, you can set it up on single router and this is what i have done in past.

create a loopbackx and enable PIM-SM on it and declare the router itself as RP using static RP using the loopback.

I would also suggest to have static igmp joins on the receiver vlans for the groups to avoid any delays in streaming.

Thanks Hitesh,

I will try that.
