vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, the command deletes all static routes for the public network.

Usage guidelines

CAUTION:

This command might interrupt network communication and cause packet forwarding failure. Before executing the command, make sure you fully understand the potential impact on the network.

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.

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.

vpn-instance d-vpn-instance-name: Specifies a destination MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If a destination VPN instance is specified, packets will search for the output interface in the destination VPN instance based on the configured next hop address.

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.

recursive-lookup host-route: Specifies only host routes for static route recursion.

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

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

bfd: Enables BFD to detect reachability of the static route's next hop. When the next hop is unreachable, the system immediately switches to the backup route.

control-packet: Specifies the BFD control mode.

bfd-source ip-address: Specifies the source IP address of BFD packets. As a best practice, specify the loopback interface address.

echo-packet: Specifies the BFD echo mode.

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.

public: Indicates that the specified next hop address is on the public network.

srv6-policy name policy-name: Specifies an SRv6 TE policy by its name for static route recursion. The policy-name argument represents the SRv6 TE policy name, a case-sensitive string of 1 to 59 characters. For more information about SRv6 TE policies, see Segment Routing Configuration Guide.

srv6-policy color color-value end-point ipv6 ipv6-address: Specifies an SRv6 TE policy by its color and endpoint attributes for static route recursion. The color-value argument represents the color attribute value of the SRv6 TE policy, in the range of 0 to 4294967295. The ipv6-address argument represents the endpoint IPv6 address of the SRv6 TE policy.

sid sid: Specifies the SRv6 SID of the tail node. Packets forwarded by the specified SRv6 TE policy will continue to be forwarded based on the specified SRv6 SID.

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. For more information about routing policies, see Layer 3—IP Routing Configuration Guide.

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.

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.

· NBMA or P2MP interfaces need IP address-to-link layer address mappings for successful packet delivery. As a best practice, specify the next hop address for the route at the same time if the output interface is an NBMA or P2MP interface.

· If the output interface is a broadcast interface, the device uses the next hop IP address to obtain the MAC address of the next hop. Therefore, you must specify both the output interface and next hop IP address.

Follow these guidelines when you configure a static route:

· Enabling BFD for a flapping route could worsen the route flapping situation. Therefore, use it with caution. For more information about BFD, see High Availability Configuration Guide.

· For static routing-Track-NQA collaboration, you must configure the same VPN instance ID for the next hop to be detected and the NQA operation.

· If a static route needs route recursion, the associated track entry must monitor the next hop of the recursive route instead of that of the static route. Otherwise, a valid route might be mistakenly considered invalid.

· Do not specify the permanent keyword together with the bfd or track keyword.

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.

Use undo ip route-static arp-request to disable periodic sending of ARP requests to the next hops of static routes.

Syntax

Default

Periodic sending of ARP requests to the next hops of static routes is disabled.

Views

System view

Predefined user roles

network-admin

Parameters

interval: Specifies an ARP request sending interval in the range of 1 to 300 seconds. The default value is 5.

Usage guidelines

When the following conditions exist, a recursive static route becomes inactive:

· The static route uses a host route to reach its direct next hop.

· The host route is obtained by specifying the recursive-lookup host-route keyword in the ip route-static command or by routing policy-based recursive lookup.

· The host route is unavailable because the direct next hop cannot send gratuitous ARP messages and consequently no ARP entry exists for that host route on the device.

To resolve this issue, you can use this command to enable the device to periodically send ARP requests to the direct next hop. When the device receives an ARP response from the direct next hop, it stops sending ARP requests and activates the recursive static route.

This command applies only to a recursive static route that meets the following requirements:

· The static route has no output interface specified.

· The static route fails the next-hop recursion.

Examples

# Enable sending of ARP requests to the next hops of static routes and set the sending interval to 10 seconds.

backup-interface interface-type interface-number: Specifies a backup output interface by its type and number. If the backup output interface is a non-P2P interface (an NBMA interface or broadcast interface), you must specify the backup next hop address.

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

bfd: Enables BFD to detect reachability of the static route's next hop. When the next hop is unreachable, the system immediately switches to the backup route.

control-packet: Specifies the BFD control mode.

bfd-source ip-address: Specifies the source IP address of BFD packets. As a best practice, specify the loopback interface address.

echo-packet: Specifies the BFD echo mode.

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

public: Specifies the public network, which indicates that the specified next hop address is on the public network.

sid sid: Specifies the SRv6 SID of the tail node. Packets forwarded by the specified SRv6 TE policy will continue to be forwarded based on the specified SRv6 SID.

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

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.

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.

· If the output interface is a broadcast interface that might have multiple next hops, you must specify both the output interface and next hop IP address.

Follow these guidelines when you configure a static route:

· Enabling BFD for a flapping route could worsen the route flapping situation. Therefore, use it with caution. For more information about BFD, see High Availability Configuration Guide.

· For static routing-Track-NQA collaboration, you must configure the same VPN instance ID for the next hop to be detected and the NQA operation.

· If a static route needs route recursion, the associated track entry must monitor the next hop of the related route instead of that of the recursive static route. Otherwise, a valid route might be mistakenly considered invalid.

· You cannot specify the permanent keyword together with the bfd and track keywords.

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 in VPN instance vpn1, whose destination address is 1.1.1.1/24, next hop address is 2.2.2.2 in VPN instance vpn2, tag value is 45, and description information is for internet.

<Sysname> system-view

[Sysname] ip route-static vpn-instance vpn1 1.1.1.1 24 vpn-instance vpn2 2.2.2.2 tag 45 description for internet

prefix

ip route-static-group

Use ip route-static-group to create a static route group and enter its view, or enter the view of an existing static route group.

Use undo ip route-static-group to delete a static route group.

Syntax

ip route-static-group group-name

undo ip route-static-group group-name

Default

No static route groups exist.

Views

System view

Predefined user roles

network-admin

Parameters

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

Examples

# Create static route group test and enter its view.

<Sysname> system-view

[Sysname] ip route-static-group test

[Sysname-route-static-group-test]

Related commands

ip route-static

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.

Views

Static route group view

Predefined user roles

network-admin

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
