What indicates to a link-state router that a neighbor is unreachable?

  • if the router no longer receives routing updates
  • if the router no longer receives hello packets
  • if the router receives an update with a hop count of 16
  • if the router receives an LSP with previously learned information
    Answers Explanation & Hints:

    OSPF routers send hello packets to monitor the state of a neighbor. When a router stops receiving hello packets from a neighbor, that neighbor is considered unreachable and the adjacency is broken.
