IPv6 static routing commands
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
Views
System view
Default level
2: System level
Parameters
vpn-instance vpn-instance-name: Specifies a VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify this option, the command deletes all IPv6 static routes for the public network.
Usage guidelines
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.

ipv6 route-static ipv6-address prefix-length { interface-type interface-number [ next-hop-address ] [ bfd { control-packet | echo-packet } | permanent ] | next-hop-address [ bfd control-packet bfd-source ipv6-address | permanent ] | vpn-instance d-vpn-instance-name next-hop-address [ bfd control-packet bfd-source ipv6-address | permanent ] } [ preference preference-value ] [ tag tag-value ] [ description description-text ]

Default

Default level
2: System level
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. Broadcast interfaces include Ethernet interfaces and VLAN interfaces.
next-hop-address: Specifies the next hop IPv6 address.
bfd: Enables BFD to detect reachability of the static route's next hop.
control-packet: Specifies the BFD control mode.
bfd-source ipv6-address: Specifies the source IPv6 address of BFD packets. As a best practice, specify the loopback interface address.
echo-packet: Specifies the BFD echo mode.
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.
public: Indicates the next hop is on the public network.
vpn-instance d-vpn-instance-name: Specifies a destination VPN 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-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.
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 (?).
vpn-instance s-vpn-instance-name: Specifies a source VPN 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.
If the output interface of an IPv6 static route is a broadcast interface, you must specify the next hop address. Broadcast interfaces include Ethernet interfaces and VLAN interfaces.
Follow these guidelines when you configure an IPv6 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.
· The next hop IPv6 address of echo packets must be a global unicast address.
· Do not specify the permanent keyword together with the bfd or track keyword.
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 configure 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.

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] ipv6 route-static default-preference 120
