routing leading to BSR.
Use show ip pim rp-hash command to check if RP information is correct; if there is not RP
information, you still need to check unicast routing.
If all attempts including Check are made but the problems on PIM-SM can’t be solved yet, then
use debug commands such debug pim/debug pim BSR please, and then copy DEBUG
information in 3 minutes and send to Technology Service Center.
28.4 MSDP Configuration
28.4.1 Introduction to MSDP
MSDP – Multicast Source Discovery Protocol, is a protocol that can learn information about
multicast source in other PIM-SM domain. The RP on which MSDP is configured will advertise
the information about the multicast sources in its domain to all the other MSDP entities through
SA messages. Thus, all the information about multicast sources in one PIM-SM domain is
spread to another. In MSDP, inter-domain information tree is used other than the shared tree. It
is required that the multicast routing protocol used for in-domain routing must be PIM-SM.
