Abstract:
   In this document, we introduce a new BGP capability termed "Long-
   lived Graceful Restart Capability" so that stale routes can be
   retained for a longer time upon session failure than is provided for
   by BGP Graceful Restart (RFC 4724).  A well-known BGP community
   "LLGR_STALE" is introduced for marking stale routes retained for a
   longer time.  A second well-known BGP community, "NO_LLGR", is
   introduced to mark routes for which these procedures should not be
   applied.  We also specify that such long-lived stale routes be
   treated as the least-preferred, and their advertisements be limited
   to BGP speakers that have advertised the new capability.  Use of this
   extension is not advisable in all cases, and we provide guidelines to
   help determine if it is.

   This memo updates RFC 6368 by specifying that the LLGR_STALE
   community must be propagated into, or out of, the path attributes
   exchanged between PE and CE.
