Inter-AS Multicast Configuration Leveraging Static RPF Peers

Network requirements

As shown in

Figure 6

, 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

messages.

It is required that the respective Loopback 0 of Device B, Device C and Device E be configured as
a C-BSR and C-RP of the respective PIM-SM domains.

It is required that Device C and Device E be configured as static RPF peers of Device B, and Device
B be configured as the only static RPF peer of Device C and Device E, so that any device can receive

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