Responsive Use of the Mobile Ad Hoc Network (MANET) Routing Protocol OLSRv2

This specification describes an optional Topology Control (TC) message that can be sent by an OLSRv2 router. This is permitted, but not suggested, by the existing protocol, but is here recommended for use in some networks. The original motivation for this message came from the circumstances of a mostly stable network, in the most extreme case updated only by messages responding to the arrival and departure of routers, in which case the additional TC message is not just recommended but required. However, the additional message could be useful in reducing the routing convergence time in any network in which messages are sent at lengthy intervals. This specification updates RFC 7181 "The Optimized Link State Routing Protocol version 2 (OLSRv2)".
