The idea is that 2002::/16 should only be announced towards peers
*from* which the operator of a 6to4 relay is willing to accept traffic
back to 6to4 hosts. So it's a route that is filtered at many places.
(There is no symmetry in 6to4 paths.)

I assume you've read RFC 6343. Your message doesn't indicate which role
you are playing, but the RFC offers specific advice for various cases.
"Don't do that" is the best advice for client hosts.
