Additional Information |
---|---|---|
n destinations |
Number of destinations for which there are routes in the routing table. |
|
n routes |
Number of routes in the routing table:
|
|
Destination |
Destination address of the route. |
|
Protocol/ Preference |
Protocol from which the route was learned: Static, Direct, Local, or the name of a particular protocol. 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 known. |
|
State |
Flags for this route. |
There are many possible flags. For a complete description, see the Junos OS Interfaces Command Reference. |
AS Path |
AS path through which the route was learned. The letters of the AS path indicate the path origin:
