MSDP Benefits

MSDP has these benefits:

MSDP Running Between RP Peers

RP + MSDP peer

PIM sparse-mode

It breaks up the shared multicast distribution tree. You can make the shared tree local to your

domain. Your local members join the local tree, and join messages for the shared tree never need to

leave your domain.

PIM sparse-mode domains can rely only on their own RPs, decreasing reliance on RPs in another

domain. This increases security because you can prevent your sources from being known outside

your domain.

Domains with only receivers can receive data without globally advertising group membership.

Global source multicast routing table state is not required, saving memory.
