My draft
(http://www.ietf.org/internet-drafts/draft-ramki-multi6-nlmp-00.txt),
together with rfc2660, takes a somewhat similar approach by marking unusable
prefixes with a special BGP attribute and both localizing and
aggregating this unreachability information in BGP. It would be great if
you can tell me what you think of it.

thanks,
