Fred,
Good explanation.
I did try scenario 6 in the lab earlier. It seems very straight
forward in the beginning; however, it took me almost 45 minutes
to get the result as per the requirement - place R2 E0 in blocking
state.
In essence, you'll think just put a very high port path-cost on
R2 E0 and it's done. Not so fast, my friend...I was wrong. Once
I put "bridge-group 1 path-cost 65000" on R2 E0, it is still in
forwarding state and R3 E0 is in bloking state!
To be more specific, in my lab, the port path cost are as follow,
* R2 S0 - 647, R2 E0 - 100
* R3 S0 - 647, R2 E0 - 100
With the path-cost range 0 - 65535, how would you solve this
problem - place R2 E0 in blocking state?
Bruce gave a good example (page 590) but didn't explain how he
came up with that magic number - 499!
Any suggestion? Thanks. (sorry I've wiped out the config and
can't post it here)
