The Optimized Link State Routing Protocol version 1 (OLSRv1) [RFC3626] is a proactive routing protocol for mobile ad hoc networks (MANETs) [RFC2501]. OLSRv1 finds the shortest, defined as minimum number of hops, routes from a router to all possible destinations.

                  Rationale for the Use of Link Metrics     in the Optimized Link State Routing Protocol Version 2 (OLSRv2)


   The Optimized Link State Routing Protocol version 2 (OLSRv2) includes    the ability to assign metrics to links and to use those metrics to    allow routing by other than minimum hop count routes.  This document    provides a historic record of the rationale for, and design    considerations behind, how link metrics were included in OLSRv2.
