Synopsis

default-information {in | out} access-list
no default-information {in | out}

Configures

Default routing information

Default

EIGRP announces the candidate default route in both incoming and outgoing updates

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.

in

Allows the protocol to receive the default route via redistribution.

out

Allows the protocol to propagate the default route via redistribution.

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.

router igrp 109
  network 10.0.0.0
  redistribute eigrp 100
  no default-information in

To disable the default routes in outgoing updates, use the no form of the command.

router eigrp 100
  network 10.0.0.0
  no default-information out
