Eric,

Could the draft clarifies the BGP Route Reflector behavior when reflecting a route received from a buggy 3107 implementation with S=0?
a) One may argue that the RR should not modify the NLRI and hence reflect the route with S=0
b) One may argue that the RR should reflect the route after setting S=1 in order to be a speaker compliant with 3107bis & 3107.
c) One may argue that this is an error and treat the IP Prefix as withdraw

IMO I think I would prefer b) in order to not propagate the bug.

Thanks,
Regards,
Bruno
