It routes all traffic that is addressed to the destination network to the interface indicated in the routing table. B. It sends a copy of its neighbor table to all adjacent routers. C. It sends a multicast query packet to all adjacent neighbors requesting available routing paths to the destination network. D. It broadcasts Hello packets to all routers in the network to re-establish neighbor adjacencies.
