◆ InvalidateRoutesWithDst()

void ns3::aodv::RoutingTable::InvalidateRoutesWithDst ( std::map< Ipv4Address, uint32_t > const & unreachable )

Update routing entries with this destination as follows:

The destination sequence number of this routing entry, if it exists and is valid, is incremented.
The entry is invalidated by marking the route entry as invalid
The Lifetime field is updated to current time plus DELETE_PERIOD.
Parameters

unreachable routes to invalidate
