Inter-AS multicastVPN

[devang_etcom]

Does pim Sparse-mode support the inter-as multicast VPN?

i guess only PIM SSM supports the multicast vpn in inter-as configuration... just to cross check...

Shivlu,

Actually, All recent IOS images use the MDT SAFI rather than the VPNv4 with a RD type 2, which was as you mentioned, a non-standard method.

You can use Dense but not recommended. But you can use both sparse-mode and sparse-dense-mode.

Remember to use MSDP to exchange between AS also bearing in mind that reachability is required if peering via loopback and best practise to specify connect-source on the MSDP Peer statement. Also use "mspd peer default" so it bypasses the RPF checkup and forwards the SA messages. Then use either Cisco PIM or BSR PIM per AS and or Anycast for the multicast domain.

Hope that helps
