With IPv6, we've got our single /32. From what I understand, if I try to advertise a /33 from the smaller POP, many (most?) will drop it (if my upstreams even take it). If I advertise the /32 from both routers, when that link goes down, my IPv6 traffic will be pretty much hosed. Is there any good solution to this?
Chris, Here's what I do with my IPv4 /24: I advertise it at higher priority at the larger POP and a slightly lower priority at the smaller POP. Then I got a small block of addresses from each upstream at each POP (from their still-aggregated blocks) to anchor a set of VPNs between the two. Something has to go disastrously wrong for me to suffer any worse effects than the occasional inefficient routing. Regards, Bill Herrin -- William D.
