ip hello-interval eigrp




ip hello-interval eigrp as-number seconds
no ip hello-interval eigrp
as-number seconds


Syntax Description:

as-number Autonomous system number.
seconds Hello interval (in seconds).


Command Description:

To configure the hello interval for the EIGRP routing process designated by an autonomous system number, use the ip hello-interval eigrp command in interface configuration mode. To restore the default value, use the no form of this command.

The default of 60 seconds applies 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. Note that for the purposes of Enhanced IGRP, Frame Relay and Switched Multimegabit Data Service (SMDS) networks may be considered to be NBMA. These networks are considered NBMA if the interface has not been configured to use physical multicasting; otherwise, they are considered not to be NBMA.


For low-speed, nonbroadcast multiaccess (NBMA) networks: 60 seconds

For all other networks: 5 seconds


The following example sets the hello interval for Ethernet interface 0 to 10 seconds:

Router(config)#interface ethernet 0
Router(config)#ip hello-interval eigrp 109 10
