[cisco-voip] Multicast in a campus network

[Ahmed Elnagar]

thanks for all replies.
 
simply I enabled multicast routing on the backbones, enabled pim on the int vlans that will be a part of the multicast domain.
and just make sure that igmp is enabled on the edge switches
thanks alot

Hello,

 

Inside a vlan and using L3 switches is exactly the same, you should enable pim and multicast routing: I would recommend using sparse mode instead dense mode. I would configure one 6509 as RP (and maybe another one as secondary for redundancy purposes) and all the leaf routers pointing to this router RP address (you can create a Loopback address). For the layer 2 switches (3560), it is enough with igmp snooping, which comes enabled by default...

 

HTH,

 

Ruben

Hello jason

 

thanks alot for your reply, I have read alot thorugh this and I know pim with its modes very well, but these all talks about multicast routing and routers configurations. I didnot pass by any document that explains these in a network where L3 switches is used for inter vlan routing. I read also about MVR but I dont know is it okay for my case or not.

Hello all;

I dont know if someone dealed before with IPTV system (but I am sure u did). The customer wants to deploy IPTV system (not cisco) and he told me that the system is using multicast for delivering TV stations to clients, I have read alot of documents regarding multiacst but I am not sure which configuration I should use to run this successfully.

The customer network consists of two backbone 6509 switch connected to it 3560 switches as edge switches, if anyone has ideas about this and how to configure these swithces (backbone and edge) to pass multicast traffic.

Also note that there will be clients in vlans other than the server vlan.

thanks
