   Multi-path Extension for the Optimized Link State Routing Protocol
                           version 2 (OLSRv2)

Abstract

   This document specifies a multi-path extension for the Optimized Link
   State Routing Protocol version 2 (OLSRv2) to discover multiple
   disjoint paths, so as to improve reliability of the OLSRv2 protocol.
   The interoperability with OLSRv2 is retained.
