That's from "debug ip routing". And when you do a default-information
command, you will "reissue" the 0/0 roue periodically (every 60 seconds as
you can see).

HTH,

Subject: EIGRP Redistribution Logs

Hi all,

Just wondering if anyone has ever experienced logs like these before. The
logs are regarding redistributing a default route from EIGRP to BGP. The
router in question is a 3845 running ADVENTERPRISE9-M version 12.4(21), The
logs go back a good while and this has been happening every second since
they started. I have checked other routers using the same config and code
and don't seem to get these logs.

I came across these whilst I was troubleshooting an issue where for some
reason my redistribution from BGP to EIGRP fails at random occassions. This
means my link fails over to the back up circuit. The only option I have is
to clear the eigrp neighbours and this resolves the issue once all the
appropriate neighbours have reformed.

Might not be anything relevant, but I just thought I would ask incase anyone
has seen this before.
