Default Metric
When redistributing routes into RIP, IGRP, and EIGRP, you must also configure the metric of
the redistributed routes. The metric can be configured in the redistribution statement or a default
metric can be configured. You can also use the command in OSPF. IS-IS does not use the
default-metric command. The default-metric command has the following syntax for IGRP
and EIGRP:
default-metric bandwidth delay reliability load mtu
The possible values for the arguments in the preceding syntax are listed in Table 10-4.
Value Ranges for default-metric Arguments
Table 10-4
Argument
Value Range
bandwidth (in kbps)
1—4,294,967,295
delay (in 10 microsecond units)
0-4,294,967,295
reliability
0-255
load
1-255
mtu
1-4,294,967,295
Example 10-14 shows a simple redistribution of RIP into EIGRP.

EIGRP Redistribution
The CCIE candidate needs to know several things regarding EIGRP redistribution. First, routes
redistributed into EIGRP have an administrative distance of 170. Second, if the autonomous
systems numbers are the same when redistributing between IGRP and EIGRP, the redistribu-
tion command is not necessary. In Figure 10-1, Router B is redistributing between EIGRP 100
and IGRP 100.
