Nope, it only triggers IGP adjacency resets at this point...

Yes, that's why you would [almost always] want to have them
co-exist and avoid the convergence/synchronization times when
a switch does occur.  You could do this with static routes
though a very trivial OSPF (or IS-IS) configuration would
make things much more automated.
