This is due to the use of secondary addresses.  By default, Unix routed
expects that it will only see routing table broadcasts from a router on its
own subnet.  But the cisco sends out a broadcast from each secondary
address, so machines on each subnet are seeing the broadcasts from the
other subnet on that cable.

You can get rid of the warning by making the router a "known" router, by
putting an entry for it in /etc/gateways, e.g.

host 222.21.248.254 gateway 222.21.248.254 metric 3 active

This routing entry will never actually be used, since you can only route
via a host on your own subnet.  But its existence keeps routed quiet.
