#IP-HELLO INTERVAL EIGRP IE VOL 4.10#

IP-HELLO INTERVAL EIGRP :

To configure the hello interval for EIGRP routing process designated by a AS
number , use the "ip hello-interval eigrp" command in interface config mode

"ip hello-interval eigrp as-number seconds"


Defaults:

For low-speed , NBMA network 60 seconds
For all other network , 5 seconds


Usage Guidelines:

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 config command.

Note that for the purposes of EIGRP, Frame relay , and Switched Multimedia 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 multicastion, otherwise , they are considered to be NBMA

#IP HOLD-TIME EIGRP#:

IP HOLD-TIME:

To configure the hold time for a particular EIGRP routing process designated
by the AS number , use the "ip hold-time eigrp" command in interface
config mode

"ip hold-time eigrp as-number seconds"

DEFAULTS:

For low speed , nonbroadcast multiaccess (NBMA) networks : 180 seconds
For all other networks : 15 seconds


Usage Guidelines:

On every congested and large networks , the default hold time might not be sufficient
time for all routers and access to servers to recieve hello packets from their
neighbors.

In this case , you may want to increase the hold time

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

Increasing the hold time delays route convergence accross the network

The default of 180 seconds hold time and 60 seconds hello interval apply only to
low-speed, NBMA media.
