Inter-AS multicast configuration by leveraging static RPF peers
Network requirements
As shown in
, AS 100 and AS 200 are two ASs running OSPF. BGP runs between the two ASs.
PIM-SM 1 belongs to AS 100, and PIM-SM 2 and PIM-SM 3 belong to AS 200. Each PIM-SM domain
has at least one multicast source or receiver.
Configure Loopback 0 as a C-BSR and C-RP of the related PIM-SM domain on Switch A, Switch D and
Switch G.
According to the RPF principle, the device can receive SA messages that pass the filtering policy from its
static RPF peers. To share multicast source information among PIM-SM domains without changing the
unicast topology structure, configure MSDP peering relationship for the RPs of the PIM-SM domains and
configure static RPF peering relationship for the MSDP peers to share multicast source information among
the PIM-SM domains.
