Weight is local to your router. (Even setting this in an outbound
route-map, there's no NLRI/BGP info available to transit this)
Local Pref is local to your AS.
MED (metric) is what is used for Inter-AS manipulations, although most
providers ignore it anyway, leading us to do things like as-path prepend and
other little tricks.
If you are trying to influence other router's decisions, you need to work
within the confines of information that BGP actually transmits in its
updates.

Subject: BGP's weight and Local Preference usage
I've change the BGP weight and local preference for routes learned form and
ebgp peer through a route-map. The result I get are that only Local
preference is changed and not weight. Assistance needed to understand why.
