A wireless network device may receive, over an interface, a broadcasted hello message that indicates network topology and interface information of neighbor nodes in a network. The wireless network device may transmit an announce message to unblocked hello peers of the wireless network device. The wireless network device may receive, on a wired interface from another node, a hello message. The wireless network device and the another node may each be identified as island heads based on the received hello message. The wired interface may be utilized for connecting the island heads.
