    Field

    Values

    Additional Information

    Static Route Addresses

    The list of static route addresses.

     

    Protocol

    Protocol from which the route was learned: Static, Direct, Local.

     

    Preference

    The preference is the individual preference value for the route.

    The route preference is used as one of the route selection criteria.

    Next-Hop

    Network layer address of the directly reachable neighboring system (if applicable) and the interface used to reach it.

    If a next hop is listed as Discard, all traffic with that destination address is discarded rather than routed. This value generally means that the route is a static route for which the discard attribute has been set.

    If a next hop is listed as Reject, all traffic with that destination address is rejected. This value generally means that the address is unreachable. For example, if the address is a configured interface address and the interface is unavailable, traffic bound for that address is rejected.

    If a next hop is listed as Local, the destination is an address on the host (either the loopback address or Ethernet management port 0 address, for example).

    Age

    How long the route has been active.

     

    State

    Flags for this route.

    There are many possible flags.
