Utilising upstream MED values

[Sam Stickland <sam_ml () spacething org>]

Hi,

We're looking at doing outbound traffic values based on upstream ("tier1") 
MED values. But, of course, there's no standard for MED values. Assuming I 
can get definations from the upstreams as to what their MED values mean, I 
have to rebase them into a common range.

However, a route-map (cisco, foundry) only allows you to set, add or 
subtract to an MED value, so this doesn't seem possible.

Is anyone doing this, and if so how?

Sam
