As promised during the recent IDR interim, we want to start a set of threads
to the IDR mailing list to clarify points discussed during that interim
about the BGP routes with color proposals.  These questions are directed to
the authors of those proposals.  The responses to those questions will be
used to drive Working Group discussion about the solution space.


Question 1: How does BGP route resolution operate with your proposal?

A BGP route, marked with a Color Extended Community C, and a nexthop NH1
needs to resolve using the proposal.  

>From the BGP routing state received from the proposed mechanism, how does
the resolving route make use of this state to decide its forwarding nexthop?

Be specific in terms of functional behavior.  There is no need to go into
implementation details unless they're helpful in explaining the functional
behavior.

If possible, please refer to relevant sections in your internet-drafts.
