thought of a hack:
set up a three tunnels to connect the spokes so you effectivly have fullmesh
create secondary addresses on the tunnels that are on the same subnet as the
rest of the frame (IOS allows subnet overlap on secondaries)
turn on isis on the secondaries
not sure if it will work
another idea:
create 2 isis processes on hub (???)
redistribute isis <--> isis
third thought:
idrp could solve this, but cisco does not support it
