Description
This command configures 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 sent in the hello messages to the neighbor. Hold time cannot be
less than three times the hello interval.
When LDP session is being set up, the holddown time is negotiated to the lower of the two peers.
Once a operational value is agreed upon, the hello factor is used to derive the value of the hello
interval.
The no form of the command at the targeted-session level sets the hello timeout and the hello factor
to the default values.
The no form of the command, at the peer level, will set the hello timeout and the hello factor to the
value defined under the targeted-session level.
Note that the session needs to be flapped for the new args to operate.
