  "abstract": "In existing specifications, the route preferences for IPv4/IPv6 Extended Reachability TLVs are not explicitly stated.  There are also inconsistencies in the definition of how the up/down bit applies to route preference when the prefix advertisement appears in Level 2 Link State Protocol Data Units (LSPs).  This document addresses these issues.",
