IGRP
Redistribution into IGRP is very similar to redistribution into RIP. When redistributing routes
into IGRP, you need to configure two items:
 The routing protocol to redistribute into IGRP
 The metric to use for the routes from the other routing protocol
These items can be configured in one of two ways:
 Add the metric to the redistribution line. This will provide the same metric for all of the
routes that are being redistributed with the redistribution line.
 Use the default-metric command with the composite metric to specify the metric for all
routes being redistributed into IGRP. You can then configure the redistribution line without
the metric attached to it. The issue with this method is that all routes from all redistributions
occurring on this router into IGRP will have the same metric.
So let’s take a look at how to configure these two different scenarios. We will start with
including the metric with the redistribution line. Refer to Figure 10.8.
We will configure one-way redistribution from RIP into IGRP AS 100 on R1:
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#router igrp 100
R1(config-router)#redistribute rip metric 100 100 200 1 1500
R1(config-router)#^Z
R1#
Now we will configure the same type of redistribution, but this time we will use the
default-metric command:
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#router igrp 100
R1(config-router)#default-metric 100 100 200 1 1500
R1(config-router)#redistribute rip
R1(config-router)#^Z
R1#
Even though IGRP and EIGRP use bandwidth and delay by default, you
must enter bandwidth, delay, reliability, load, and MTU when redistributing
into them.
