3Com Switch 8800 Family Configuration Guide

476 CHAPTER 45: MSDP CONFIGURATION
If the SA message is sent from a MSDP peer in a different domain which is the next
autonomous domain along the optimal path to the RP in the domain of source, as
from Switch D to Switch F, it is received and forwarded to other peers.
For other SA messages, they are neither received nor forwarded.
Precautions for configuration
The router operating MSDP must also run BGP or MBGP. It is recommended to use
the same IP address of the MSDP peer with that of the BGP peer or MBGP peer. If
neither BGP nor MBGP is in operation, a static RPF peer should be configured.
