Terminating 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.
● Terminate the TCP connection with a peer.
CONFIGURATION mode
ip msdp shutdown
After the relationship is terminated, the peering state of the terminator is SHUTDOWN, while the peering state of the peer is
INACTIVE.
