display ip routing-table ip-address Syntax display ip routing-table ip-address [ mask-length | mask ] [ longer-match ] [ verbose ] display ip routing-table ip-address1 { mask-length | mask } ip-address2 { mask-length | mask } [ verbose ]

View Any view

Default level 1: Monitor level

Parameters ip-address: Specifies the destination IP address, in dotted decimal format. mask-length: Specifies the IP address mask length in the range 0 to 32. mask: Specifies the IP address mask in dotted decimal format. longer-match: Displays the route with the longest mask. verbose: Displays detailed routing table information, including both active and inactive routes. With this argument absent, the command displays only brief information about active routes.

Description Use the display ip routing-table ip-address command to display information about routes to a specified destination address. 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 corresponding 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

15

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 corresponding 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.

Static routing configuration commands

The term “router” in this document refers to a router in a generic sense or a Layer 3 switch.

delete static-routes all Syntax delete static-routes all

View System view

Default level 2: System level

Parameters None

Description Use the delete static-routes all command to delete all static routes. When you use this command to delete static routes, the system will prompt you to confirm the operation before deleting all the static routes. Related commands: ip route-static and display ip routing-table in IP Routing Basics Commands.

Examples Delete all static routes on the router. system-view [Sysname] delete static-routes all This will erase all ipv4 static routes and their configurations, you must reconf igure all static routes Are you sure?[Y/N]:Y

ip route-static Syntax ip route-static dest-address { mask | mask-length } { next-hop-address | interface-type interfacenumber next-hop-address } [ preference preference-value ] [ description description-text ] undo ip route-static dest-address { mask | mask-length } [ next-hop-address | interface-type interfacenumber [ next-hop-address ] ] [ preference preference-value ] 21

View System view

Default level 2: System level

Parameters dest-address: Specifies the destination IP address of the static route, in dotted decimal notation. mask: Specifies the mask of the IP address, in dotted decimal notation. mask-length: Specifies the mask length, in the range 0 to 32. next-hop-address: Specifies the IP address of the next hop, in dotted decimal notation. interface-type interface-number: Specifies the output interface by its type and number. If the output interface is a broadcast interface, such as an Ethernet interface, a virtual template, or a VLAN interface, the next hop address must be specified. preference preference-value : Specifies the preference of the static route, which is in the range 1 to 255 and defaults to 60. description description-text: Configures a description for the static route, which consists of 1 to 60 characters, including special characters like space, but excluding ? (question mark).

Description Use the ip route-static command to configure a unicast static route. Use the undo ip route-static command to delete a unicast static route. When configuring a unicast static route, note the following:

•

If the destination IP address and the mask are both 0.0.0.0, the configured route is a default route. If routing table searching fails, the router will use the default route for packet forwarding.

•

Different route management policies can be implemented for different route preference configurations. For example, specifying the same preference for different routes to the same destination address enables load sharing, while specifying different preferences for these routes enables route backup.

•

When configuring a static route, you can specify the output interface or the next hop address based on the actual requirement. The next hop address must not be the IP address of the local interface; otherwise, the route configuration will not take effect. For interfaces that support network address to link layer address resolution or point-to-point interfaces, you can specify the output interface or next hop address. When specifying the output interface, note the following:

○ For a Null 0 interface, if the output interface has already been configured, there is no need to configure the next hop address.

○ If you specify a broadcast interface (such as a VLAN interface) as the output interface, you must specify the corresponding next hop of the interface at the same time.

Related commands: ip route-static default-preference and display ip routing-table in IP Routing Basics Commands.

22

• The static route does not take effect if you specify its next hop address first and then configure the address as the IP address of a local interface, such as VLAN interface. • To configure track monitoring for an existing static route, simply associate the static route with a track entry. For a non-existent static route, configure it, and associate it with a track entry. • If a static route needs route recursion, the associated track entry must monitor the nexthop of the recursive route instead of that of the static route; otherwise, a valid route may be mistakenly considered invalid.

Examples Configure a static route whose destination address is 1.1.1.1/24, next hop address is 2.2.2.2, and description information is for internet & intranet. system-view [Sysname] ip route-static 1.1.1.1 24 2.2.2.2 description for internet & intranet

ip route-static default-preference Syntax ip route-static default-preference default-preference-value undo ip route-static default-preference

View System view

Default level 2: System level

Parameters default-preference-value: Specifies the default preference for static routes, which is in the range 1 to 255.

Description Use the ip route-static default-preference command to configure the default preference for static routes. Use the undo ip route-static default-preference command to restore the default. By default, the default preference of static routes is 60. Note the following:

•

If no preference is specified when configuring a static route, the default preference is used.

•

When the default preference is re-configured, it applies only to newly added static routes.

Related commands: ip route-static and display ip routing-table in IP Routing Basics Commands.

23

Examples Set the default preference of static routes to 120. system-view [Sysname] ip route-static default-preference 120
