May be different routing based on where the tunnel leads?

I recently got Comcast residential native IPv6 working (sort of - bricked a
Belkin reflashing dd-wrt, but plugging the laptop into the cablemodem directly
does dhcpv6 just fine).  IPv6 to work is about 30% faster than IPv4, because
cogent routes v6 for us better:

Apparently, going Blacksburg-ashburn-blacksburg is a lot faster than
blacksburg-ashburn-atlanta-DC-blacbksburg. Who'd thunk it? :)
