Multi-Topology Extension
for the Optimized Link State Routing Protocol Version 2 (OLSRv2)
Abstract
This specification describes an extension to the Optimized Link State
Routing Protocol version 2 (OLSRv2) to support multiple routing
topologies, while retaining interoperability with OLSRv2 routers that
do not implement this extension.
This specification updates RFCs 7188 and 7631 by modifying and
extending TLV registries and descriptions.
