Hi, John.

192.88.99.0/24 which is the 6to4 anycast network.  Do we really
want to be filtering that prefix?

Good question.  I'm re-reading RFC 3068 now, and the RFC appears to
allow for the advertisement of this prefix into the global table.
I'm wondering if this is wise, however.  It seems this prefix would
best be used internally.  What do others think?

Thanks,
Rob.

I believe the idea is that it typically comes from outside
one's domain because it's supposed to allow edge islands of
IPv6 to find the mainland.  If you had a connection to the
mainland under your control, you wouldn't need this trick to
get there.

At least that's my understanding.
