Example:
switch(config-router-af)# maximum-paths 5
Step 5

Example:
switch(config-router-af)# copy running-config
startup-config
This example shows how to configure equal cost load balancing for EIGRP over IPv4 with a maximum
of six equal cost paths:
switch# configure terminal
switch(config)# router eigrp Test1
switch(config-router)# maximum-paths 6
switch(config-router)# copy running-config startup-config

Adjusting the Interval Between Hello Packets and the Hold Time

You can adjust the interval between Hello messages and the hold time.
By default, Hello messages are sent every 5 seconds. The hold time is advertised in Hello messages and
indicates to neighbors the length of time that they should consider the sender valid. The default hold time
is three times the hello interval, or 15 seconds.
To change the interval between hello packets, use the following command in interface configuration
mode:
Command
switch(config-if)# ip hello-interval
eigrp instance-tag seconds
Example:
switch(config-if)# ip hello-interval
eigrp Test1 30
On very congested and large networks, the default hold time might not be sufficient time for all routers
to receive hello packets from their neighbors. In this case, you might want to increase the hold time.
To change the hold time, use the following command in interface configuration mode:
Command
switch(config-if)# ip hold-time eigrp
instance-tag seconds
Example:
switch(config-if)# ip hold-time eigrp
Test1 30
Use the show ip eigrp interface detail command to verify timer configuration.

4-22
Purpose
Sets the number of equal cost paths that
EIGRP will accept in the route table. The
range is from 1 to 16. The default is 8.
(Optional) Saves this configuration change.
Purpose
Configures the hello interval for an EIGRP routing
process. The instance tag can be any case-sensitive,
alphanumeric string up to 20 characters. The range is
from 1 to 65535 seconds. The default is 5.
Purpose
Configures the hold time for an EIGRP routing process.
The instance tag can be any case-sensitive,
alphanumeric string up to 20 characters. The range is
from 1 to 65535.
