[c-nsp] NX-OS Default MSDP Peer

[Pavel Stefanov]

Thanks Adam. I recall reading a very good doc explaining the RPF checks 
on SA messages on Cisco kit but I can't seem to find it on their website 
anymore...

I think the second option with the mesh group is the option that will do 
the job as there are multiple MSDP peers on each device and the MSDP 
originator ID/peer address is unique on each router part of the Anycast 
RP in each domain. The routers peering the two domains together need to 
propage the SA messages from the other peers in the domestic mesh group 
to the other domain so to do that, I think I will need a second mesh 
group with a single peer in the remote domain.
