Oops, missed that. If you're setting *lower* weight and higher local_pref,
the *higher* weighted path will be preferred and the lower priority attribute
(i.e. local_pref) won't be considered (then you can look at the
synchronization thing.)...

Using route maps I set lower weight and higher local pref on routes from a particular AS to try and force traffic to prefer traffic from a different AS on another router. It still chose the external routes on the locally connected internet interface versus from the other router advetising external routes via IBGP between routers.

Each router prefers the external routes off of the local internet connected interface - so traffic is basically evenly split 50/50. Want a 80/20 or similar distribution.
