Experts, I'm playing around with some different multicast scenarios and I thought it was possible to make MCast Interdomain Routing without using mBGP between the MSDP Peers.
Here's what I have: Cat2---Cat4---R5---BB3 Full reachability exist between all routers. Domain 1 (Cat2 & Cat4) - pim sparse on all relevant interfaces - Cat4 is bsr-candidate and rp-candidate for group 226.0.0.0/8 - Cat2 loopback0 has ip igmp-join for 226.1.1.1 - Both routers able to ping 226.1.1.1 - bsr-border is configured on the link between Cat4 & R5 - msdp peer & default peer command is configured for loopback IP address of R5 Domain 2 (R5 & BB3) - pim sparse on all relevant interfaces - R5 is bsr-candidate and rp-candidate for group 225.0.0.0/8 - BB3 loopback0 has ip igmp-join for 225.1.1.1 - Both routers able to ping 225.1.1.1 - bsr-border is configured on the link between R5 & Cat4 -msdp peer & default peer command is configured for the loopback IP address of Cat4 When I try to ping any of the groups from the other Domain I get the following message: RPF lookup failed for source or RP Is the only way to get around this is to configure mBGP between the RPs??
