Command:

ip hold-time eigrp


Mode:

Router(config-if)#


Syntax:

ip hold-time eigrp as-number seconds
no ip hold-time eigrp as-number seconds

 

Syntax Description:

as-number Autonomous system number.
seconds Hold time (in seconds).

 

Command Description:

To configure the hold time for a particular Enhanced IGRP (EIGRP) routing process designated by the autonomous system number, use the ip hold-time eigrp command in interface configuration mode. To restore the default value, use the no form of this command.

On very congested and large networks, the default hold time might not be sufficient time for all routers and access servers to receive hello packets from their neighbors. In this case, you may want to increase the hold time.

We recommend that the hold time be at least three times the hello interval. If a router does not receive a hello packet within the specified hold time, routes through this router are considered unavailable.

Increasing the hold time delays route convergence across the network.

The default of 180 seconds hold time and 60 seconds hello interval apply only to low-speed, NBMA media. Low speed is considered to be a rate of T1 or slower, as specified with the bandwidth interface configuration command.

Defaults:

For low-speed, nonbroadcast multiaccess (NBMA) networks: 180 seconds

For all other networks: 15 seconds


Example:

The following example sets the hold time for Ethernet interface 0 to 40 seconds:

Router(config-if)#interface ethernet 0
Router(config-if)#ip hold-time eigrp 109 40


Misconceptions:

None
