Static RPF Peer
Configuration Example
Network requirements
■ Two ISPs maintains their ASs, 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 one or more
receivers. OSPF runs within each domain to provide unicast routes.
■ PIM-SM 2 and PIM-SM 3 are both PIM stub domains, and BGP is not required
between these two domains and PIM-SM 1. Instead, static RPF peers are
configured to avoid RPF check on SA messages.
■ The respective loopback interfaces of Switch C, Switch D and Switch F are
configured as the C-BSR and C-RP of the respective PIM-SM domains.
■ The static RPF peers of Switch C are Switch D and Switch F, while Switch C is
the only RPF peer of Switch D and Switch F. Any switch can receive SA
messages sent by its static RPF peer(s) and permitted by the corresponding
filtering policy.
