Although it did a few other things as well, an attempt at standardizing
parts of this failed:
draft-bonaventure-bgp-redistribution-01
This draft included:
IDRP style DIST_LIST_INCL, DIST_LIST_EXCL
Proxied NO_EXPORT
Proxied Prepending
The IDRP-style DIST_LISTs seem to generate most of the heat. We never
got a firm feel for why the other two componenents were disliked.
Geoff Huston proposed draft-huston-nopeer-00.txt to attempt to address
some of the route propagation issues that the DIST_LISTs were intended
to address.
