Parameters
initial initial-time: Specifies the LDP backoff initial delay time in the range of 15 to 50331 seconds.
maximum maximum-time: Specifies the LDP backoff maximum delay time in the range of 120 to 50331
seconds.
Usage guidelines
LDP peers continually negotiate with each other until a session is set up. If LDP peers use incompatible
negotiation parameters (for example, different label advertisement modes), a large amount of
negotiation traffic will enter the network. To suppress LDP session negotiation traffic, use this command
to control the interval between negotiation attempts.
