Allows
each domain to control its own RP(s)
|
|
|
• |
Interconnect
RPs between domains with TCP connections to pass
|
|
|
source
active messages (SAs)
|
|
|

Can
also be used within a domain to provide RP redundancy
|
|
|
(Anycast-RP)
|
|
|
• |
RPs
send SA messages for internal sources to MSDP peers
|
|
|
• |
SAs
are Peer-RPF checked before accepting or forwarding
|
|
|
• |
RPs
learn about external sources via SA messages and may trigger
|
|
(S,G)joins
on behalf of local receivers

MSDP
connections typically parallel MBGP connections
