pretty trivial to write an expect script to reconfigure the gigaswitch hourly based on a freshly-refreshed arp cache. as regards mac level filtering on your router, i suppose that would depend on the overhead to implement such filtering on your particular box. and i am not enough of a cisco wizard to be able to answer that question for the 75xx series. ---Rob From: dvv@sprint.net (Dima Volodin) Hmmmm, a good idea - make your router to accept packets with src MAC addresses of its BGP peers only, no?

You don't mean changing one MAC address in Gigaswitch configuration is a bolder feat than swapping (failed) equipment, do you?
what i just said to him: "yeah, but the ip addresses don't. ever hear of arp?"
