Inter-AS Multicast Configuration Leveraging Static RPF Peers

Network requirements

There are two ASs in the network, AS 100 and AS 200 respectively. OSPF is running within each

AS, and BGP is running between the two ASs.

PIM-SM 1 belongs to AS 100, while PIM-SM 2 and PIM-SM 3 belong to AS 200.

Each PIM-SM domain has zero or one multicast source and receiver. OSPF runs within each

domain to provide unicast routes.

PIM-SM 2 and PIM-SM 3 are both stub domains, and BGP or MBGP is not required between these

two domains and PIM-SM 1. Instead, static RPF peers are configured to avoid RPF check on SA

It is required that the respective loopback 0 of Switch B, Switch C and Switch E be configured as

the C-BSR and C-RP of the respective PIM-SM domains.

It is required that Switch C and Switch E be configured as static RPF peers of Switch B, and Switch

B be configured as the only static RPF peer of Switch C and Switch E, so that any switch can

receive SA messages only from its static RPF peer(s) and permitted by the corresponding filtering
