6.7.2 Inter-AS Multicast Configuration Leveraging Static RPF Peers

I. 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 messages.
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 policy.
