One thing that annoys me to no end is that if router X sends out
prefix A::/64 and router Y sends out B::/64, then node 1 will happily
configure addresses A::1 and B::1, and then send out packets with
source address A::1 over router Y. This is really a bad thing for
efforts like shim6.

	first of all, the above configuration violates RFC.  all routers has
	to be configured with consistent RA parameters iirc.  i know it is not

it happen quite easy on a network, just configure two devices that announce RA :)

the host will pick up both and use one of them, havent seen a pattern on which one it choice tho.
