Configuration for EIGRP or IGRP

To configure the default metric for IGRP or EIGRP, use the following command syntax:

default-metric bandwidth delay reliability loading mtu

Typically, you should take the values shown on one of the outgoing interfaces of the router being configured, by issuing this exec command:

show interface

The significance of the metric values is shown in Table 10-5.

Table 10-5 The Parameters of the default metric Command

Command Parameter



The minimum bandwidth seen on route to the destination. It is presented

in kilobits/per second (kbps).


The delay experienced on the route and presented in microseconds.


The probability of a successful transmission given the history of this

interface. The value is expressed in a number from 0 to 255, where 255 is

indicates that the route is stable and available.


A number range of 0 to 255, where 255 indicates that the line is 100

percent loaded.


The maximum packet size that can travel through the network.

The default metric command is used in Example 10-2 and is illustrated in Figure 10-8.

Example 10-2 shows the configuration of the default metric when redistributing between routing protocols.

Beware of route feedback causing poor network performance.
