Multicast Neighbour

[feroz syed]

Attached topology, as you can see there are two vrf Red and Blue, the vpnv4 is working file, i have reachability from R1 to R7 via vpvn4,  enabled multicast on R3 and R1 sparse-mode and R5, R7 act as server. R1 joined multicast group address ip igmp join-group 229.1.1.1. i can see the *,G on Router 3 but the neighbor on R5 not showing,

Hello,

tough one. Can you post the running configs of all participating routers ?

Hi

 R7 is server and member of VRF Blue but I see no VRF definition on it.

However the interface on R5, direclty connect does:

interface FastEthernet2/1
ip vrf forwarding BLUE
ip address 172.57.57.5 255.255.255.0
ip pim sparse-mode
duplex auto
speed auto
mpls ip
!

[feroz syed]

R7 is server, it just respond to multicast traffic (ping) also i cannot configure vrf on Customer router R7

[Flavio Miranda]

But how can it participate of the VRF domain?  Which means your traffic is actually going through the VRF global anyway?

[paul driver]

Hello
Try appending the following using MSDP so you can join the two :PM-SM domain together 

all rtrs
ip pim rp-address x.x.x.x ( address of RP)

R3
ip msdp peer 5.5.5.5 connect-as loopback 0

r5
ip msdp peer 3.3.3.3 connect-as loopback 0
