Hi Alsontra,
I guess your first statment in the route-map is the problem.
The 1st statement is simply setting weight for anything to 6000, so any
route will be matched by this statmment and no route will reach permit 20
statment to be evaluated.
You need to make it checked before - change its sequesnce from 20 to 5 for
example.
Try reversing the logi. If it worked for you but screwed the other task then
you need to set your match/set commands in a way to acheive all your
requirements.
Regards,
Yasser
