Description

When redistributing EIGRP into IGRP, you can use this command to allow (or suppress, using the no form of the command) the redistribution of the default routes or exterior routes from EIGRP. By default, all exterior routes (including default routes) are passed between IGRP and EIGRP.

out

access-list

The number or name of a simple access list that permits or denies the default routes you want to propagate.

Example

The following commands prevent IGRP from receiving exterior or default routes via redistribution from EIGRP.

  redistribute eigrp 100
