IP Routing Basics Configuration Commands
display ip routing-table
Syntax
display ip routing-table [ verbose ]
View
Any view
Default Level
1: Monitor level
Parameters
verbose: Displays detailed routing table information, including that for inactive routes. With this keyword absent, the command displays only summary information about active routes.
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, preference, cost, next hop and outbound interface. This command only displays the routes currently in use, that is, the optimal routes.
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.
Examples
# Display brief information about active routes in the routing table.
<Sysname> display ip routing-table

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. Holddown is a route advertisement policy used in some distance vector (D-V) routing protocols, such as RIP, to avoid the propagation of some incorrect routes. It distributes a Holddown route during a period regardless of whether a new route to the same destination is found. For details, refer to corresponding routing protocols. |
|
|
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 |
Normally, among routes to a destination, the route with the highest preference is installed into the core routing table and advertised, while a NotInstall route cannot be installed into the core routing table but may 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. |
