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 you do not specify the next-hop-address argument following this option, the device searches for the output interface in the specified destination VPN instance for packets matching the static route. If you specify the next-hop-address argument and this option, the device searches for the output interface in the specified destination VPN instance based on the specified next hop address for packets matching the static route.

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 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.

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. For more information about BFD, see High Availability Configuration Guide.

control-packet: Specifies the BFD control packet 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 packet mode.

static session-name: Associates the static route with a static BFD session. The session-name argument represents the static BFD session name, a case-sensitive string of 1 to 64 characters. If you specify a nonexistent static BFD session, you must create the static BFD session to have the association take effect.

permanent: Specifies the route as a permanent static route. After you specify this keyword, the static route will always be active, even if the output interface is down.

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.

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

remote-sid remote-sid locator-prefix-len: Enables the static route to forward packets in SRv6 BE mode. The remote-sid argument specifies the SRv6 SID of the SRv6 BE destination node. The locator-prefix-len argument specifies the locator length for the SRv6 SID. The remote-sid and locator-prefix-len arguments uniquely identifies a locator. The device will perform SRv6 encapsulation for packets and forward the packets according to the IGP routes associated with the locator.

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 endpoint. Packets forwarded through the SRv6 TE policy will be further forwarded based on the 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.

no-advertise: Disables advertisement for the static route. With this keyword, the static route can be imported to the IGP or BGP routing table, but cannot be advertised to neighbors. If multiple next hops are configured for the same static route prefix, the device flushes only the optimal static routes to the IP routing table. If the optimal static routes are imported to the IGP or BGP routing table, you must specify this keyword for each optimal static route. If you do not specify this keyword for an optimal static route, the device still can advertise that route to neighbors.

description text: Configures a description of 1 to 150 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 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 BFD for a static route:

· To use a static BFD session to detect next hop reachability for a static route, you must perform the following tasks:

¡ Specify the IP address of the output interface of the static route as the source address of the static BFD session.

¡ Specify the IP address of the next hop of the static route as the peer address of the static BFD session.

· Enabling BFD for a flapping route could worsen the route flapping situation. Therefore, use it with caution.

Follow these guidelines when you associate a static route with a track entry:

· 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 the 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.

To specify the recursive-lookup host-route keyword, you must enable ARP direct route advertisement to advertise 32-bit host routes on the output interface corresponding to the next hop. To enable ARP direct route advertisement, use the arp route-direct advertise command.

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.

If you specify both the remote-sid remote-sid locator-prefix-len option and srv6-policy keyword, the static route is preferentially recursed to the SRv6 TE policy. When the SRv6 TE policy becomes unavailable, the static route will forward packets in SRv6 BE mode.

The remote-sid and sid keywords are mutually exclusive. You cannot specify both of them.

prefix

ip route-static bfd

Use ip route-static bfd to configure BFD session parameters for a static route.

Use undo ip route-static bfd to restore the default.

Syntax

BFD control packet mode for single-hop detection and BFD echo packet mode:

ip route-static bfd interface-type interface-number next-hop-address { detect-multiplier detect-multiplier | min-echo-receive-interval min-echo-receive-interval | min-receive-interval min-receive-interval | min-transmit-interval min-transmit-interval } *

undo ip route-static bfd [ vpn-instance d-vpn-instance-name ] next-hop-address

Default

No BFD session parameters are specifically configured for a static route. The static route uses the session parameters configured for the BFD module (common BFD session parameters).

Parameters

interface-type interface-number: Specifies an output interface by its type and number.

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 the next hop of the static route belongs to the public network, do not specify this option.

next-hop-address: Specifies the IP address of the next hop, in dotted decimal notation.

source-ip ip-address: Specifies a source IPv4 address for BFD packets, in dotted decimal notation.

detect-multiplier detect-multiplier: Sets the BFD detection time multiplier. The value range for the detect-multiplier argument is 3 to 50. The default value is 5.

min-echo-receive-interval min-echo-receive-interval: Sets the minimum interval for receiving BFD echo packets, in milliseconds. The value range for the min-echo-receive-interval argument is 3 to 10000.

min-receive-interval min-receive-interval: Sets the minimum interval for receiving BFD control packets, in milliseconds. The value range for the min-receive-interval argument is 3 to 10000.

min-transmit-interval min-transmit-interval: Sets the minimum interval for transmitting BFD control packets, in milliseconds. The value range for the min-transmit-interval argument is 3 to 10000.

Usage guidelines

Use this command to configure BFD session parameters for a static route, including parameters that determine the BFD detection time. The BFD detection time = detect-multiplier × max (min-echo-receive-interval, min-receive-interval, min-transmit-interval). For more information about the calculation method of BFD detection time, see BFD in High Availability Command Reference.

If you specify the output interface when executing this command, support for the BFD session parameters varies by BFD session mode.

· Echo-mode BFD sessions support only the min-echo-receive-interval and detect-multiplier parameters.

· Control-mode BFD sessions for single-hop detection support only the min-receive-interval, min-transmit-interval, and detect-multiplier parameters.

To apply the configured BFD session parameters, use one of the following combinations of parameters to specify a static route:

· In control packet mode for single-hop detection and in echo packet mode, use the output interface and next hop address.

· In control packet mode for multihop detection, use the next hop address and BFD packet source address. If the next hop belongs to a VPN instance, use the destination VPN instance, next hop address, and BFD packet source address to specify the static route.

For an unspecified BFD session parameter, the static route uses the value of the corresponding common BFD session parameter.

Examples

# Configure BFD session parameters for the static route with output interface Ten-GigabitEthernet 3/1/1 and next hop 1.2.3.4. The BFD detection time multiplier is 20 and the minimum interval for receiving BFD echo packets is 1000 milliseconds.

When the default preference is reconfigured, it applies only to newly added static routes.

Examples

# Set a default preference of 120 for static routes.

<Sysname> system-view

[Sysname] ip route-static default-preference 120

undo ip route-static recursive-lookup segment-routing-ipv6

Default

Static routes are not allowed to inherit the SRv6 encapsulation information of the related routes obtained through route recursion.

Views

System view

Predefined user roles

network-admin

Usage guidelines

Route recursion is required if the next hop of a static route is not directly connected. By default, a static route does not inherit the SRv6 encapsulation information of the related route obtained through route recursion if the next hop of the static route is recursed to an SRv6 BE or SRv6 TE policy path. That is, the device does not add SRv6 encapsulation to the packets that match the static route. The packets are forwarded out of the output interface according to the recursion result.

To allow a static route to inherit the SRv6 encapsulation information of the related route obtained through route recursion when the next hop of the static route is recursed to an SRv6 BE or SRv6 TE policy path, use this command. With this command, the device adds SRv6 encapsulation to the packets that match the static route and forwards the encapsulated packets in SRv6 BE mode or through the matching SRv6 TE policy.

For more information about the SRv6 BE mode, see IP L3VPN over SRv6 configuration or public network IP over SRv6 configuration in Segment Routing Configuration Guide. For more information about SRv6 TE policies, see SRv6 TE policy configuration in Segment Routing Configuration Guide.

# Allow static routes to inherit the SRv6 encapsulation information of the related routes obtained through route recursion.

undo ip route-static recursive-lookup tunnel

Default

Static routes cannot recurse to LSP tunnels.

Views

System view

Predefined user roles

network-admin

Parameters

prefix-list ipv4-prefix-list-name: Specifies an IPv4 prefix list by its name, a case-sensitive string of 1 to 63 characters. Only static routes filtered by the specified IPv4 prefix list can recurse to LSP tunnels. If you do not specify an IPv4 prefix list, this command allows all static routes to recurse to LSP tunnels.

tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 126 characters. Static routes can recurse only to LSP tunnels that match the specified tunnel policy. If you do not specify a tunnel policy, this command allows static routes to recurse to any LSP tunnels.

Usage guidelines

By default, a static route can recurse only to output interfaces and next hops based on IP forwarding. This command allows the device to preferentially recurse static routes to LSP tunnels. If a static route cannot recurse to an LSP tunnel, the device recurses the static route to an output interface and next hop based on IP forwarding.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Enable the device to recurse static routes to LSP tunnels.

Parameters

s-vpn-instance-name: Specifies a source MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. Each VPN instance has its own routing table, and the configured static route is installed in the routing tables of the specified VPN instances.

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.

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 a non-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.

control-packet: Specifies the BFD control packet 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 packet mode.

permanent: Specifies the route as a permanent static route. After you specify this keyword, the static route will always be active, even if the output interface is down.

public: Specifies the public network. If you specify this keyword following the next-hop-address argument, the next hop is on the public network. The device searches for the output interface in the public network based on the next hop address for packets matching the static route. If you specify the next-hop-address argument without specifying the public keyword, the device searches for the output interface in the source VPN instance based on the next hop address for packets matching the static route. If you specify the public keyword without specifying the next-hop-address argument, the device searches for the output interface in the public network for packets matching the static route.

sid sid: Specifies the SRv6 SID of the endpoint. Packets forwarded through the SRv6 TE policy will be further forwarded based on the 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 150 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.

If you specify a destination VPN instance but do not specify a next hop address, the source and destination VPN instances cannot be the same one.

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 (for example, an Ethernet interface or VLAN 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 BFD for a static route:

· To use a static BFD session to detect next hop reachability for a static route, the static BFD session and the next hop of the static route must belong to the same VPN instance. In addition, you must perform the following tasks:

¡ Specify the IP address of the output interface of the static route as the source address of the static BFD session.

¡ Specify the IP address of the next hop of the static route as the peer address of the static BFD session.

· Enabling BFD for a flapping route could worsen the route flapping situation. Therefore, use it with caution.

Follow these guidelines when you associate a static route with a track entry:

· 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 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.

The remote-sid and sid keywords are mutually exclusive. You cannot specify both of them.

If a VPN instance has been specified as the destination VPN instance, you cannot specify the vpn-instance d-vpn-instance-name option when configuring a static route for the VPN instance by using this command.

A static route with a destination VPN instance specified supports only VXLAN tunnels.

If the action of a PBR node specifies only the default next hop and default SRv6 TE policy for packets, follow these restrictions and guidelines when executing this command:

¡ You cannot configure static routes for the VPN instance in the match criteria of the PBR node.

¡ The dest-address argument cannot specify the destination IP address in the match criteria of the PBR node.

For more information about PBR, see policy-based routing configuration in Layer 3—IP Routing Configuration Guide.

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.

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
