Static routing commands

delete static-routes all

Use delete static-routes all to delete all static routes.

Syntax

delete static-routes all

Views

network-admin

Usage guidelines

When you use this command, the system will prompt you to confirm the operation before deleting all the static routes.

To delete one static route, use the undo ip route-static command. To delete all static routes, including the default route, use the delete static-routes all command.

Examples

# Delete all static routes.

<Sysname> system-view

[Sysname] delete static-routes all

This will erase all IPv4 static routes and their configurations, you must reconfigure all static routes.

Are you sure?[Y/N]:y

Syntax

ip route-static { dest-address { mask-length | mask } | group group-name } interface-type interface-number [ next-hop-address ] [ backup-interface interface-type interface-number [ backup-nexthop backup-nexthop-address ] [ permanent ] | permanent | track track-entry-number ] [ preference preference ] [ tag tag-value ] [ description text ]

undo ip route-static { dest-address { mask-length | mask } | group group-name } [ interface-type interface-number [ next-hop-address ] | next-hop-address ] [ preference preference ]

Default

Parameters

dest-address: Specifies the destination IP address of the static route, in dotted decimal notation.

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

mask: Specifies the subnet mask in dotted decimal notation.

group group-name: Specifies a static route group by its name, a case-sensitive string of 1 to 31 characters.

interface-type interface-number: Specifies an output interface by its type and number. For more information, see Layer 3—IP Routing Configuration Guide.

next-hop-address: Specifies the IP address of the next hop, in dotted decimal notation. For more information, see Layer 3—IP Routing Configuration Guide.

backup-interface interface-type interface-number: Specifies a backup output interface by its type and number. If the backup output interface is an NBMA interface or broadcast interface and not a P2P interface, you must specify the backup next hop address.

backup-nexthop backup-nexthop-address: Specifies a backup next hop address.

permanent: Specifies the route as a permanent static route. If the output interface is down, the permanent static route is still active.

track track-entry-number: Associates the static route with a track entry specified by its number in the range of 1 to 1024. For more information about Track, see High Availability Configuration Guide.

preference preference: Specifies a preference for the static route, in the range of 1 to 255. The default is 60.

tag tag-value: Sets a tag value for marking the static route, in the range of 1 to 4294967295. The default is 0. Tags of routes are used for route control in routing policies.

description text: Configures a description of 1 to 60 characters for the static route. The description can include special characters, such as the space, except the question mark (?).

Usage guidelines

If the destination IP address and the mask are both 0.0.0.0 (or 0), the configured route is a default route. The default route is used for forwarding a packet matching no entry in the routing table.

Implement different routing policies to configure different route preferences. For example, to enable load sharing for multiple routes to the same destination, assign the same preference to the routes. To enable the routes to back up one another, assign different preferences to them. Only the WX2540E and WX2540H access controllers support load sharing and route backup.

Follow these guidelines when you specify the output interface or the next hop address of the static route:

·     If the output interface is a Null 0 interface, no next hop address is required.

·     If the output interface is a point-to-point interface, you can specify only the output interface. You do not need to change the configuration of the route even if the peer address is changed.

·     Multiple next hops might exist if the output interface is a broadcast interface (for example, an Ethernet interface or VLAN interface). You must specify both the output interface and next hop IP address for the static route.

If you specify a static route group, all prefixes in the static route group will be assigned the next hop and output interface specified by using this command.

Examples

# Configure a static route, whose destination address is 1.1.1.1/24, next hop address is 2.2.2.2, tag value is 45, and description information is for internet.

<Sysname> system-view

[Sysname] ip route-static 1.1.1.1 24 2.2.2.2 tag 45 description for internet

Parameters

default-preference: Specifies a default preference for static routes, in the range of 1 to 255.

Usage guidelines

If no preference is specified for a static route, the default preference applies.

# Set a default preference of 120 for static routes.

<Sysname> system-view

[Sysname] ip route-static default-preference 120

prefix

Use prefix to add a static route prefix to a static route group.

Use undo prefix to delete a static route prefix from a static route group.

Syntax

prefix dest-address { mask-length | mask }

undo prefix dest-address { mask-length | mask }

Default

No static route prefix is added to a static route group.

Parameters

dest-address: Specifies the destination IP address of the static route, in dotted decimal notation.

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

mask: Specifies the subnet mask in dotted decimal notation.

Usage guidelines

Execute this command repeatedly to add multiple static route prefixes to a static route group.

After you add static route prefixes to a static route group, you can specify that group in the ip route-static group command to configure static routes with the prefixes. To configure more static routes, you only need to add new static route prefixes to the group.

Examples

# Add static route prefix 1.1.1.1/32 to static route group test.

<Sysname> system-view

[Sysname] ip route-static-group test

[Sysname-route-static-group-test] prefix 1.1.1.1 32
