Title: OSPF Database Exchange Summary List

This document describes a backward-compatible optimization for the
Database Exchange process in OSPFv2 and OSPFv3. In this optimization,
a router does not list a Link State Advertisement (LSA) in Database
Description packets sent to a neighbor, if the same or a more recent
instance of the LSA was listed in a Database Description packet
already received from the neighbor. This optimization reduces
Database Description overhead by about 50% in large networks. This
optimization does not affect synchronization, since it only omits
unnecessary information from Database Description packets. This memo
provides information for the Internet community.
INFORMATIONAL: This memo provides information for the Internet community.
It does not specify an Internet standard of any kind. Distribution of
this memo is unlimited.
