Predefined user roles

network-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.

Are you sure?[Y/N]:y

Parameters

nib-id: Specifies a NIB by its ID, a hexadecimal string in the range of 1 to ffffffff.

verbose: Displays detailed IPv6 static route next hop information. If you do not specify this keyword, the command displays brief IPv6 static route next hop information.

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 (for example, an NBMA interface or broadcast interface), the next hop address must be specified.

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

recursive-lookup longest-match: Specifies the longest match principle for static route recursion.

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

control-packet: Specifies the BFD control packet mode.

echo-packet: Specifies the BFD echo packet mode.

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

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 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 (?).

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.

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 a source IPv6 address for BFD packets on the local device, you must specify that 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 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 keyword.

If you do not specify the recursive-lookup longest-match keyword, the device preferentially recurses the IPv6 static route to a direct route. If no matching direct route is found, the device performs IPv6 static route recursion based on the longest match principle. When recursing the IPv6 static route to a direct route, the device takes the next hop of the IPv6 static route as directly connected. In fact, the next hop might be incorrect and packets might fail to be forwarded based on the IPv6 static route.

If you specify the recursive-lookup longest-match keyword, the device performs IPv6 static route recursion based on the longest match principle to make sure that the next hop is correct.

Examples

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

Parameters

default-preference: 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.

echo-packet: Specifies the BFD echo packet mode.

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

public: Indicates the next hop is on the public network.

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.

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.

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.

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

·     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 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.

·     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.

·     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.

·     You cannot specify both the permanent and bfd keywords.
