My thoughts are to speed up reconvergence upon loss of the spoke
route.... Of course I'm assuming that the only way to the spoke route is
through the spoke.
For the lab though maybe its not necessary?????
Interested to hear your thoughts though cause now that I think about it
I neved did this for v4RIP over frame either on a spoke router. I just
let the IGP go through its normal hold down and flush routines.
I guess it might be used as a way to speed up convergence on loss of the
spoke originated routes and quite possibly an option for doing such on
the lab. IOW, "speed up the convergence of spoke originated routes. Do
not adjust the RIP timers."

Why would you need to do this? The metric will increment when the route
is received back automatically.
