As long as they have a /24 that they can announce, two or more upstreams that are able and willing to establish BGP sessions with them and a router with enough memory to hold at least 2 full views (for a Cisco, you probably want 256MB or more these days), they can multi (or dual) home. I don't think Verio, Sprint or any other major ISP is filtering out /24s from any part of IP4 any more. I don't think there are many ISPs willing to establish BGP sessions for customers that aren't spending at least T1 prices with them. Verizon is going to be rolling out cheap, multimegabyte fiber connections to business and residential customers around here soon. Since I'm paying ~$2k/mo for 2 T1s (with longish loops and a /21), it's tempting to see if I could get ahold of somebody over there willing to talk about BGP :) James Smallacombe PlantageNet, Inc.
