MSDP + MBGP has worked well for us. MBGP does the routing + tcp connection + rpf checks. It uses the multicast address family extension of BGP and configs are similar to your unicast BGP configs.
MSDP connects a chosen RP from your domain to another RP from your peer domain to exchange multicast sources. Ofcourse you can apply filters to limit what groups you want to exchange information for. We use the GLOP range (233.x.x.x) and filter everything else HTH Shanawaz _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
