Hello,

My /var/log/messages file is constantly filled with this message. I will
output a tail of it...

I believe it is being generated from my ZyXEL cable router. (ZyXEL P964).
If I disconnect the ethernet cable going to it, the messages subside, and
once I reconnect it, they start again.

I would like to be able to eliminate it from showing up in the logs as it
is really useless and just clutters things up a bit. Here is some
relevant command output:

netstat -rnfinet

dc0: has no effect or use right now, it still happens when this is

tun0: is being used for vpn stuff, messages continue even with tun0 down.

This is OpenBSD3.5-stable / i386

The ZyXEL router is not configured to be offering DHCP as well.
If anyone has any ideas on what this is, or at least how to filter it out
of the logs, I do appreciate it. Thanks,
