Description
This command configures the hold time. This is the time interval to wait before declaring a
neighbor down. The factor parameter derives the hello interval.
Hold time is local to the system and is sent in the hello messages to the neighbor. Hold time
cannot be less than three times the hello interval. The hold time can be configured globally
(applies to all LDP interfaces) or per interface. The most specific value is used.
When an LDP session is being set up, the hold time is negotiated to the lower of the two
peers. Once an operational value is agreed upon, the hello factor is used to derive the value
of the hello interval.
