3Com MSR 50 Series Configuration Manual page 1155

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 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 Router C, Router D and Router F
■
be configured as a C-BSR and C-RP of the respective PIM-SM domains.
It is required that Router D and Router F be configured as static RPF peers of
■
Router C, and Router C be configured as the only static RPF peer of Router D
and Router F, so that any router can receive SA messages only from its static
RPF peer(s) and permitted by the corresponding filtering policy.
