Additional Information

Static Route Addresses

The list of static route addresses.

 

Protocol/

Protocol from which the route was learned: Static, Direct, Local, or the name of a particular protocol.

 

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 type

The next-hope type for the route.

If a next hop type 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 known.

 

State

Flags for this route.

There are many possible flags.

AS Path

AS path through which the route was learned. The letters of the AS path indicate the path origin:

  • I — IGP.
  • E — EGP.
  • ? — Incomplete. Typically, the AS path was aggregated.
 

Route Information
