Abstract

Packets are routed in a data network comprising a wireless mesh network and a controller providing IPv6 management traffic to nodes of the wireless network. A monitor function and a route table manager are used to generate a route table relating IPv6 addresses to each of the nodes via a respective one of a plurality of POP nodes, by accessing a pre-configured topology file, determining the reachability of each of the plurality of POP nodes from the controller by periodically sending test messages from the monitor function to each POP and detecting acknowledgement of the test messages. If a POP node is not reachable, the route table is updated to relate the IPv6 subnet of the POP that is not reachable to the address of a POP node that is reachable. A Layer 2 network is used to direct the IPv6 management traffic according to the amended route table.
