  or, use link-local address on IX switch as documented in
  draft-kato-bgp-ipv6-link-local-01.txt.

  Unfortunatly, that technique does not have broad commercial
  implementation. In addition, there was some pushback from
  the IETF IDR wg on using this technique. So its still a bit
  "iffy", although a very elegent "haq". (we used it in LA
  for a while but could not get folks to adopt it.)
