Rogue host route in IS-IS database

Unanswered Question
Mar 23rd, 2010

During the testing, a loopback address was added to a C6k box (running 12.2(18)SXF7). This loopback interface was marked as 'passive' within IS-IS and was entered into the IS-IS topology database and advertised to all other IS-IS peers. Subsequently, the loopback interface was removed (and configrmed with 'sh ip route', etc), but the route is still present in the IS-IS topology, and is being advertised to the rest of the network. Is there any way to remove this rogue host route without a restart of IS-IS on the box advertising the route?

I have this problem too.
