Inter-AS Multicast Configuration Leveraging Static RPF Peers
Network requirements
z
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.
z
PIM-SM 1 belongs to AS 100, while PIM-SM 2 and PIM-SM 3 belong to AS 200.
z
Each PIM-SM domain has zero or one multicast source and receiver. OSPF runs within each
domain to provide unicast routes.
z
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.
z
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.
z
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.
