Bridged-routed connect: the magic

•There are several variants of routed pdus across different platforms, mostly also useless to us. •But on 6500 OSM blades Cisco has developed a 1483 bridged/routed encap that does just what we wanted: allow ethernets to connect to atms. Uses proxy arp and other ugly stuff internally. •Best part was that we only needed it for the transition, so we borrowed the $60K blade for 6 months & then returned it when all atm gone.
