multicast with MSDP, BGP and PIM

Jacek Tymoczko

Hi,

 

I'm new into multicast and I got a setup to do, we have already a multicast running on our Catalyst 6500 VSS. But recently we need to peer with a customer and get a multicast from him using MSDP, BGP and PIM.

 

First, I would like to somehow "isolate" current multicast from the one I will be receiving from the new customer on this peer connection. So normally now the multicast clients are in Vlan110 and I want them be there. But for new customer multicast I would like to have new VLAN for clients. So I was wondering how to achieve multiple Randezvous Point (RP) ? I read about static RP with filter, but one filter per RP is possible, and on the RP 172.16.10.1 I got few multicast groups addresses, so that is kind of tricky. 

 

I was also wondering to create a new VRF for that connection and put the port which will be peering with the customer in that VRF. Would it make easier ?

 

Below I put the parts of config which refer to multicast and OSPF we run now for our internal multicast. 

 

Any help would be welcomed. 

 

The config is as follows:

ip multicast-routing
ip multicast-routing vrf backend
 
interface Vlan110
 ip vrf forwarding backend
 ip address 172.16.10.1 255.255.255.0

 no ip unreachables
 no ip proxy-arp
 ip flow ingress
 ip pim sparse-mode
 
interface Vlan300
 ip vrf forwarding backend
 ip address 192.168.1.1 255.255.255.128
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip flow ingress
 ip pim dr-priority 255
 ip pim sparse-mode
