selectively modify route administrative distances

Unanswered Question
Feb 23rd, 2008

We are attempting to modify the administrative distance (AD) of selective routes, redistributed into EIGRP.

The approach we have taken is with the following config on the router receiving the redistributed routes;

router eigrp 12345

distance 80 mod-ad

ip access-list standard mod-ad



Our understanding is that the DISTANCE command under the EIGRP section would change the AD of routes received from matching the permits in acl MOD-AD, to the new AD of 80.

What we have found is that even though we see hits on the ACL, the AD for the routes and are still 170.

Are we mistaken in our understanding of the use of this DISTANCE command?

Is there another way to selectively (we know about the global change option - DISTANCE EIGRP 90 80) modify the AD?

One thing to note, in the show access-list output of MOD-AD, we see the following -> what does the "check=#" mean?;

permit wildcard bits matches) check=48

permit, wildcard bits matches) check=7239

Thank you

I have this problem too.

I believe that i've faced this issue before, unfortunately with this command you can't influence external routes, you need to use the "distance eigrp" form of the command, which can't be used to selectively change the AD.
