ipv6 route-static

Use ipv6 route-static to configure an IPv6 static route.

Use undo ipv6 route-static to remove an IPv6 static route.

Syntax

ipv6 route-static ipv6-address prefix-length { interface-type interface-number [ next-hop-address ] | next-hop-address [ permanent ] } [ preference preference-value ] [ tag tag-value ] [ description description-text ]

undo ipv6 route-static ipv6-address prefix-length [ interface-type interface-number [ next-hop-address ] | next-hop-address ] [ preference preference-value ]

Default

No IPv6 static route is configured.

Predefined user roles

network-admin

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 not a point-to-point (P2P) interface, the next hop address must be specified. Non-P2P interfaces include Ethernet interfaces and VLAN interfaces.

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

permanent: Specifies the IPv6 route as a permanent IPv6 static route. If the output interface is down, the permanent IPv6 static route is still active. Support for this keyword depends on the device model.

preference preference-value: 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.

description 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 (?).

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.

If the output interface is a broadcast interface, the next hop address must be specified. Broadcast interfaces include Ethernet interfaces and VLAN interfaces.

Examples

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

<Sysname> system-view

[Sysname] ipv6 route-static 1:1:2:: 64 1:1:3::1

ipv6 route-static default-preference

Use ipv6 route-static default-preference to set a default preference for IPv6 static routes.

Use undo ipv6 route-static default-preference to restore the default.

Syntax

ipv6 route-static default-preference default-preference-value

undo ipv6 route-static default-preference

Default

The default preference of IPv6 static routes is 60.

Views

System view

Predefined user roles

network-admin

Parameters

default-preference-value: Specifies a default preference for IPv6 static routes, in the range of 1 to 255.

Usage guidelines

If no preference is specified for an IPv6 static route, the default preference applies.

When the default preference is reconfigured, it applies only to newly added IPv6 static routes.

Examples

# Set a default preference of 120 for IPv6 static routes.

<Sysname> system-view

[Sysname] ipv6 route-static default-preference 120
