FYI: I just added the following text as a proposed requirement
For IPv6 multihoming solutions.

"IPv6 multihoming solutions MUST be compatible with sites that
implement RPF checks or filtering that prevents traffic to be sent
back from a different interface it came in."

I welcome your comments on:

1. Is this posting on-topic for the 6bone list? In other words, is
it appropriate to post here some multi6 topics that have
implications for the 6bone folks for the benefit of those who do
not subscribe to the multi6 mailing list?

2. if yes, the text itself.

Michel.
