[Users] ibsim updates routing tables?

I'm trying to test routing in ibsim, but it doesn't seem to update the
routing tables in the simulated switches. If I take a link down using the
clear command in ibsim, I see opensm saying that it is updating the routing
tables and that it completes, but I can't ibtracert to the LID who's path
was taken down.

Should ibsim and opensm be reconfiguring routing in the simulated
environment? No matter which routing protocol I select in opensm, the
routes are always the same, even having opensm re-LID the entire fabric
doesn't help. Any help would be appreciated.

Output from opensm:

******************************************************************
