I have a customer that is using a Cisco 3661 with a ATM OC3 card to terminate their DSL clients. They are currently using RBE in preference to standard 1483 bridging. With RBE if I'm not wrong, what it does among other things, instead of giving each sub-int an ip address, along with DHCP it creates a dynamic route in the routing table and bind the customer's PC MAC address to that PVC to avoid possible spoofing, unlike Bridged 1483. My problem is that I need to be able to "clear" these dynamic routes so I can take a computer from PVC 1/32 to 1/33 without having to change out the NIC! I've tried a 'clear ip cache', clear ip rout, clear int atm6/0. Nothing seems to work. Any enlightenment would be appreciated.
