IPv6 static routing commands

Non-default vSystems do not support some of the IPv6 static routing commands. For information about vSystem support for a command, see the usage guidelines on that command. For information about vSystem, see Virtual Technologies Configuration Guide.

delete ipv6 static-routes all

Use delete ipv6 static-routes all to delete all IPv6 static routes.

Syntax

delete ipv6 [ vpn-instance vpn-instance-name ] static-routes all

Predefined user roles

network-admin

context-admin

vsys-admin

Parameters

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 IPv6 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 IPv6 static routes.

Examples

# Delete all IPv6 static routes.

<Sysname> system-view

[Sysname] delete ipv6 static-routes all

This will erase all IPv6 static routes and their configurations, you must reconfigure all static routes.

Parameters

ipv6-address prefix-length: Specifies the IPv6 address and prefix length.

interface-type interface-number: Specifies an output interface by its type and number. If the output interface is an NBMA interface or broadcast interface and not a point-to-point (P2P) interface, the next hop address must be specified.

next-hop-address: Specifies the next hop IPv6 address.

gateway: Specifies the next hop IPv6 address of the IPv6 static route as the gateway address obtained by the interface in IPv6 address autoconfiguration. When the gateway address changes, the device automatically updates the next hop IPv6 address of the IPv6 static route accordingly. For more information about IPv6 address autoconfiguration, see IPv6 basics and DHCPv6 in Layer 3—IP Services Configuration Guide.

bfd: Enables BFD to detect reachability of the static route's next hop.

control-packet: Specifies the BFD control packet mode.

bfd-source ipv6-address: Specifies the source IPv6 address of BFD packets.

echo-packet: Specifies the BFD echo packet mode.

static session-name: Associates a static BFD session with the IPv6 static route. The session-name argument specifies a static BFD session by its name, a case-sensitive string of 1 to 64 characters. If you specify a nonexistent static BFD session, the configuration takes effect after you create the static BFD session.

permanent: Specifies the IPv6 route as a permanent IPv6 static route. After you specify this keyword, the IPv6 static route will always be active, even if the output interface is down.

track track-entry-number: Associates the IPv6 static route with a track entry specified by its number in the range of 1 to 1024. For more information about Track, see Network Management and Monitoring Configuration Guide. Non-default vSystems do not support this parameter.

public: Indicates the following depending on the configuration view.

·     Default vSystem view—Indicates the next hop is on the public network.

¡     With this keyword specified, the system searches for an output interface for the IPv6 static route from the public network IPv6 routing table based on the specified next hop.

¡     Without this keyword and the destination VPN instance specified, the next hop of the IPv6 static route belongs to the source VPN instance. In this case, the system searches for an output interface for the IPv6 static route from the routing table of the source VPN instance based on the specified next hop.

·     Non-default vSystem view—Specifies the default vSystem where the destination IPv6 address of the IPv6 static route resides. If you specify this keyword, you do not need to specify a next hop IPv6 address.

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 is specified, packets will search for the output interface based on the specified next hop (IPv6 address) for the static route.

preference preference: Specifies a preference for IPv6 static routes, in the range of 1 to 255. The default is 60.

tag tag-value: Sets a tag 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 for the IPv6 static route, which consists of 1 to 60 characters, including special characters such as the space, but excluding the question mark (?).

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

Usage guidelines

An IPv6 static route that has the destination address configured as ::/0 (a prefix length of 0) is the default IPv6 route. If the destination address of an IPv6 packet does not match any entry in the routing table, this default route is used to forward the packet.

To realize intercommunication between the default vSystem and a non-default vSystem or between two non-default vSystems, use the following commands:

·     In the system view of the default vSystem, execute the ipv6 route-static ipv6-address prefix-length vpn-instance d-vpn-instance-name [ preference preference ] [ tag tag-value ] [ description text ] command. This command allows the default vSystem to access a non-default vSystem. The d-vpn-instance-name argument specifies the name of the VPN instance that has the same name as the non-default vSystem.

·     In the system view of the default vSystem, execute the ipv6 route-static vpn-instance s-vpn-instance-name ipv6-address prefix-length vpn-instance d-vpn-instance-name [ preference preference ] [ tag tag-value ] [ description text ] command. This command allows intercommunication between two non-default vSystems. The s-vpn-instance-name and d-vpn-instance-name arguments specify the names of the VPN instances that have the same names as the non-default vSystems.

·     In the system view of a non-default vSystem, execute the ipv6 route-static ipv6-address prefix-length public [ preference preference ] [ tag tag-value ] [ description text ] command. This command allows the non-default vSystem to access the default vSystem.

Follow these guidelines to configure the output interface, next hop address, or both for a static route:

·     If the output interface is a broadcast interface or an NBMA interface, the next hop address must be specified.

·     If the output interface is a P2P 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.

Follow these guidelines when you configure BFD for IPv6 static routes:

·     If you specify the source IPv6 address of BFD packets, you must specify the IPv6 address as the next hop IPv6 address on the peer device.

·     If you specify a non-P2P output interface and a direct next hop, specify the bfd-source ipv6-address option as a best practice. Make sure the source IPv6 address of BFD packets meets the following requirements:

¡     The address is the same as the IPv6 address of the output interface.

¡     The address is on the same network segment as the next hop IPv6 address of the same type.

For example, if the next hop IPv6 address is a link-local address, the source IPv6 address of BFD packets must also be a link-local 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 Network Management and Monitoring Configuration Guide.

·     The next hop IPv6 address of echo packets must be a global unicast address.

For IPv6 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 specified interface has not obtained the gateway address, the IPv6 static route with the gateway address as the next hop address does not take effect.

# Configure an IPv6 static route, with the destination address 1:1:2::/64 and next hop 1:1:3::1.
