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
messages.
• It is required that the respective Loopback 0 of Firewall B, Firewall C and Firewall E be configured
as a C-BSR and C-RP of the respective PIM-SM domains.
• It is required that Firewall C and Firewall E be configured as static RPF peers of Firewall B, and
Firewall B be configured as the only static RPF peer of Firewall C and Firewall E, so that any firewall
can receive SA messages only from its static RPF peer(s) and permitted by the corresponding
filtering policy.
