Inter-AS multicast configuration leveraging static RPF peers

Network requirements
As shown in
•
each other.
PIM-SM 1 belongs to AS 100, and 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.
Loopback 0 of Switch B, Switch C, and Switch E must be configured as the C-BSR and C-RP of the
•
PIM-SM domains respectively.
Switch C and Switch E must be configured as static RPF peers of Switch B, and Switch B must be
•
configured as the only static RPF peer of Switch C and Switch E, so that any switch can receive SA
messages from only its static RPF peers and permitted by the corresponding filtering policy.
