Configuring the Interval for LDP Keepalive Messages
The keepalive interval determines how often a message is sent over the session to ensure that the keepalive timeout is not exceeded. If no other LDP traffic is sent over the session in this much time, a keepalive message is sent. The default is 10 seconds. The minimum value is 1 second.
The value configured for the keepalive interval can be altered during LDP session negotiation if the value configured for the LDP hold time on the peer router or switch is lower than the value configured locally.
