ESR routers have the ability to flexibly configure Hello holdtime, Hello interval and Keepalive holdtime settings.
Example of configuring Hello holdtime for an LDP session:
ESR# show run mpls
mpls
 ldp
 router-id 4.4.4.4
  discovery hello holdtime 40
 address-family ipv4
 interface gigabitethernet 1/0/4
      discovery hello holdtime 60
 exit
 exit
 enable
exit
If the Hello Holdtime and Hello Interval parameters are not specified, the default values are used. If parameters
are specified, the priority of values for address-family will be higher than for globally configured values.

the LDP process.

For a TCP session, Keepalive holdtime is also a matching parameter similar to Hold timer. Keepalive interval is
calculated automatically and equals Keepalive holdtime/3. Keepalive holdtime can be set globally as well as
for each neighbor. The timer set for a particular neighbor is a higher priority.
