Usage Guidelines

Usage Scenario

After MSDP peers establish a TCP connection, the display msdp brief command can be used to display the brief information about the remote MSDP peer, such as the address, AS number, the number of (S, G) entries, and the status of the TCP connection.

Precautions

This command displays summary information about the status of MSDP peers only when the MSDP peer has been configured.

MSDP specifies that the peer with the higher IP address acts as the server and listens at port 639. The peer with the lower IP address acts as client and enables the connection. If the connection fails, the client enables the connection again.

Example
