Parameters
keepalive: Sets a keepalive timer in the range of 1 to 21845 seconds.
holdtime: Sets a peer hold timer in the range of 1 to 65535 seconds.
Usage guidelines
MSDP peers periodically send keepalive messages to each other to keep a session alive. When a session
is established, an MSDP peer sends a keepalive message to its peer and starts a keepalive timer and a
peer hold timer. When the keepalive timer expires, the MSDP peer sends a new keepalive message. If
the MSDP peer receives an MSDP message from its peer before the peer hold timer expires, it resets the
peer hold timer. Otherwise, the MSDP peer closes the session.
When you configure this command, follow these guidelines:
• You must set the same keepalive timer and peer hold timer for the MSDP peers of a session, because
there is no negotiation mechanism for the two timers.
• The keepalive timer must be less than the peer hold timer.
• This command immediately takes effect on the established MSDP session.
Examples
# Set the keepalive timer and peer hold timer for the MSDP session on the public network to 60 seconds
and 180 seconds, respectively.
