You shouldn't have added the vif statement in your configuration
even during the startup.

FYI, I tried to repeat your experiment, but I couldn't trigger the
above error (and the rtrmgr crash below).
What version of XORP are you using and what OS?
In my experiment I was using the lastest XORP code from CVS and
Linux (Fedora Core 4).
