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 detailed information, see
relevant 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
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.
State
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.

5
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.

ip-address: Destination IP address, in dotted decimal format.
mask | mask-length: IP address mask, in dotted decimal format or represented by an integer in the range
0 to 32.
longer-match: Displays the route with the longest mask.

argument absent, the command displays only brief information about active routes.
|: Filters command output by specifying a regular expression. For more information about regular
expressions, see the Fundamentals Configuration Guide.
begin: Displays the first line that matches the specified regular expression and all lines that follow.
exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.
regular-expression: Specifies a regular expression, which is a case sensitive string of 1 to 256 characters.
Description
Use the display ip routing-table ip-address command to display information about routes to a specified
destination address.

6
Executing the command with different parameters yields different output:
•display ip routing-table ip-address
The system ANDs the input destination IP address with the subnet mask in each route entry; and ANDs
the destination IP address in each route entry with its own subnet mask.
If the two operations yield the same result for an entry and this entry is active, it is displayed.
•display ip routing-table ip-address mask
The system ANDs the input destination IP address with the input subnet mask; and ANDs the destination
IP address in each route entry with the input subnet mask.
If the two operations yield the same result for an entry and the entry is active with a subnet mask less than
or equal to the input subnet mask, the entry is displayed.
Only route entries that exactly match the input destination address and mask are displayed.
•display ip routing-table ip-address longer-match
The system ANDs the input destination IP address with the subnet mask in each route entry; and ANDs
the destination IP address in each route entry with its own subnet mask.
If the two operations yield the same result for multiple entries that are active, the one with longest mask
length is displayed.
•display ip routing-table ip-address mask longer-match
The system ANDs the input destination IP address with the input subnet mask; and ANDs the destination
IP address in each route entry with the input subnet mask.
If the two operations yield the same result for multiple entries with a mask less than or equal to the input
subnet mask, the one that is active with longest mask length is displayed.
Use the display ip routing-table ip-address1 { mask-length | mask } ip-address2 { mask-length | mask }
command to display route entries with destination addresses within a specified range.

or equal to the input prefix length, the entry is displayed.
Only route entries that exactly match the input destination address and prefix length are displayed.
•display ipv6 routing-table ipv6-address prefix-length longer-match
The system ANDs the input destination IPv6 address with the input prefix length; and ANDs the
destination IPv6 address in each route entry with the input prefix length.
If the two operations yield the same result for multiple entries with a prefix length less than or equal to the
input prefix length, the one that is active with the longest prefix length is displayed.

# Display brief information about the route matching the specified destination IPv6 address.
