Sparse-Mode Routing Protocols - Dynamically Finding RPs and Using Redundant RPs - Interdomain Multicast Routing with MSDP

3 important questions on Sparse-Mode Routing Protocols - Dynamically Finding RPs and Using Redundant RPs - Interdomain Multicast Routing with MSDP

What is the abbreviation for MSDP?

multicast source discovery protocol

How does MSDP work?


The RP in each domain establishes an MSDP peering session
using a TCP connection with the RPs in other domains or
with border routers leading to the other domains.

When the RP learns about a new multicast source within its own
domain (through the normal PIM register mechanism), the RP
encapsulates the first data packet in a Source-Active (SA)
message and sends the SA to all MSDP peers

What is the command to configure a MSDP peer?

(config)#ip msdp peer ip
