Re: default route in EIGRP

Hi,

"default-information" command in EIGRP will not originate a default route as like OSPF. It works a bit different.

It instructs the router to accept/advertise the default candidate network. (Hope you remember IGRP doesnt advertise 0.0.0.0 network and so we use ip default-network command)

Say you have the below tpology,

R1------------R2------

10.0.0.0 11.0.0.0

In R2, if you configure "ip default-network 11.0.0.0" command.

11.0.0.0 network will be marked as default candidate network in R1 as below,

D* 11.0.0.0/8

Now configure "no default-information in" in R1, clear the EIGRP neighbor and check the table. 11.0.0.0 will not be marked as default candidate network.

HTH,

Re: default route in EIGRP

Hi,

Do you want this static route to be redistributed into your EIGRP domain?. If so, you can use the following command..

ip route 0.0.0.0 0.0.0.0 10.0.0.254

router eigrp 1

redistribute static metric 10000 1 255 10 1500

Re: default route in EIGRP

You are correct. In current code EIGRP does not implement the default-information-originate function. In a presentation at the Networkers conference it was stated that it is planned for EIGRP to implement this in some future release. But current code for EIGRP does not do this.
