Got me there Mark ;-)! But the ECP question he was working on here is meant to be solved with IRB. The IP address isn't only
for management.

Subject: RE: bridging between serial and ethernet
Normally when using no ip routing, I would configure the same IP address
on each interface that needed to be managed. Both configs look ok - but
I would test them first before given my seal of approval ;p
Incidently you never seen a ethernet switch with an ip addresses on it?
Thanks,
