Table 2 Command output

Field

Description

Destination

Destination address/mask length.

Protocol

Protocol that installed the route.

Preference

Preference of the route.

Cost

Cost of the route.

IpPrecedence

IP precedence.

QosLcId

Local QoS ID.

NextHop

Next hop address of the route.

Interface

Output interface for packets to be forwarded along the route.

RelyNextHop

Next hop address obtained through routing recursion.

Neighbor

Neighboring address determined by the routing protocol.

BKTunnel ID

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 routing protocols, such as RIP, to avoid the propagation of incorrect routes. It distributes a Holddown route during a period regardless of whether a new route to the same destination is found. For more information, refer to 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.

·     NotInstallThe route with the highest priority among the routes to a destination 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 are dropped. The router sends ICMP unreachable messages to the sources of the dropped packets. The Reject routes are typically 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.

 

display ip routing-table ip-address

Use display ip routing-table ip-address to display information about routes to a specific destination address.

Use display ip routing-table ip-address1 { mask-length | mask } ip-address2 { mask-length | mask } to display information about active routes whose destinations and masks fall into the specified address range.

Syntax

display ip routing-table ip-address [ mask | mask-length ] [ longer-match ] [ verbose ] [ | { begin | exclude | include } regular-expression ]

display ip routing-table ip-address1 { mask | mask-length } ip-address2 { mask | mask-length } [ verbose ] [ | { begin | exclude | include } regular-expression ]

Views

Default command level

1: Monitor level

Parameters

ip-address: Specifies a destination IP address, in dotted decimal notation.

mask: Specifies the mask length, in dotted decimal notation.

mask-length: Specifies the mask length, an integer in the range of 0 to 32.

longer-match: Displays the route with the longest mask.

verbose: Displays detailed information about all routes. Without this argument, the command displays only brief information about active routes.

|: Filters command output by specifying a regular expression. For more information about regular expressions, see 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, a case-sensitive string of 1 to 256 characters.

Usage guidelines

Executing the command with different parameters yields the following results:

·     display ip routing-table ip-address:

¡     The system ANDs the input destination IP address with the subnet mask in each route entry.

¡     The system 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, the entry is displayed.

·     display ip routing-table ip-address mask:

¡     The system ANDs the input destination IP address with the input subnet mask.

¡     The system 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.

·     display ip routing-table ip-address longer-match:

¡     The system ANDs the input destination IP address with the subnet mask in each route entry.

¡     The system 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 entry with the 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.

¡     The system 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 entry that is active with the longest mask length is displayed.
