Hi Authors of RFC 7117,

I have one doubt about the following description in RFC 7117.

[description]: The best route procedures ensure that if multiple ASBRs, in an AS, receive the same Inter-AS A-D route from their EBGP neighbors, only one of these ASBRs propagates this route in Internal BGP (IBGP).

[weiguo]: How to coordinate differnent ASBRs in an AS to ensure only one of the ASBRs propagates A-D routes to local AS in IBGP?
IMO, all ASBRs can propagate the A-D routes to remote PE in local AS, the remote PE pick one route as best route, the PE can only accept traffic data from the ASBR that advertises the best route.

Thanks
