Description
Use the display ip routing-table command to display brief information about active routes in the routing table.
This command displays brief information about a routing table, with a routing entry contained in one line. The information displayed includes destination IP address/mask length, protocol, priority, cost, next hop and outbound interface. This command displays only the optimal routes in use.
Use the display ip routing-table verbose command to display detailed information about all routes in the routing table.
This command displays detailed information about all active and inactive routes, including the statistics of the entire routing table and information for each route.

Neighbour | Neighboring address determined by Routing Protocol | |
Tunnel ID | Tunnel ID | |
Label | Label | |
State | Route status: | |
Active | This is an active unicast route. | |
Adv | This route can be advertised. | |
Delete | This route is deleted. | |
Gateway | This is an indirect route. | |
Holddown | Number of holddown routes. | |
Int | The route was discovered by an Interior Gateway Protocol (IGP). | |
NoAdv | The route is not advertised when the router advertises routes based on policies. | |
NotInstall | Among routes to a destination, the route with the highest priority is installed into the core routing table and advertised. A NotInstall route cannot be installed into the core routing table but can be advertised. | |
Reject | The packets matching a Reject route will be dropped. Besides, the router sends ICMP unreachable messages to the sources of the dropped packets. The Reject routes are usually used for network testing. | |
Static | A static route is not lost when you perform the save operation and then restart the router. Routes configured manually are marked as static. | |
Unicast | Unicast routes | |
Inactive | Inactive routes | |
Invalid | Invalid routes | |
WaitQ | The route is the WaitQ during route recursion. | |
TunE | Tunnel | |
GotQ | The route is in the GotQ during route recursion. | |
Age | Time for which the route has been in the routing table, in the sequence of hour, minute, and second from left to right. | |
Tag | Route tag | |
