My read on it ( after checking Halabi's and Stewart's books ) is that LOCAL_PREF is typically set on the inbound side, not with the outbound side. LOCAL_PREF is an optional attribute. You don't want others to be able to impose their criteria on you. also - are you remembering to use the bgp send-communities switch? > > Thank you. > Sincerely, > CN > > > > > > > _________________________________________________________________ > Add photos to your e-mail with MSN 8.
