Log Changes in Peership States
Terminate a Peership
MSDP uses TCP as its transport protocol. In a peering relationship, the peer with the lower IP address
initiates the TCP session, while the peer with the higher IP address listens on port 639.
Once the relationship is terminated, the peering state of the terminator is SHUTDOWN, while the peering
state of the peer is INACTIVE.
