(RADIATOR) cisco-avpair for a route-map ?

Hello Kurt -

I think you are going to have to do some lab testing to see if/how  
you can get this to work.

It really depends on whether the Cisco accepts a cisco-avpair to do  
this (or not).

Has anyone on the list got any operational experience with this?

regards

Hugh
