If I need public IP addresses at a smaller remote office (VPN Citrix whatever), I either have to get them from one ISP, the other, do some weird multiple IP's on a host with source routing thing, or BGP. Isn't BGP traditionally the solution for multi-homing/redundancy? At which point you have two options: 1. the IPv6 routing table is small ~256k routes, so just take a full table 2. use a prefix length filter appropriate for your given situation Routers that can handle multiple 256k route tables are not expensive if you're willing to live with something other than the big players at a branch office.
