1 IP Routing Table Commands
The term “router” in this document refers to a router in a generic sense or a Layer 3 switch.
IP Routing Table Commands
display ip routing-table
Syntax
display ip routing-table [ verbose ||{ begin |exclude |include } regular-expression ]
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 brief information about active routes.
|: Uses a regular expression to filter output information. For details about regular expressions, refer to
CLI Configuration in the Fundamentals Configuration Guide.
begin: Displays route entries starting from the one specified by the regular expression.
exclude: Displays route entries not matching the regular expression.
include: Displays route entries matching the regular expression.
regular-expression: Regular expression, a string of 1 to 256 case-sensitive characters used for
specifying routing entries.
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 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.

1-2
This command displays detailed information about all active and inactive routes, including the statistics
of the entire routing table and information for each route.

Field Description
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
Normally, among routes to a destination, the route with the highest
priority 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
State
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
