apply access-vpn vpn-instance

Use apply access-vpn vpn-instance to set a VPN instances.

Use undo apply access-vpn vpn-instance to remove the specified VPN instance.

Syntax

apply access-vpn vpn-instance vpn-instance-name

undo apply access-vpn vpn-instance [ vpn-instance-name ]

Default

No VPN instance is specified for a node.

Parameters

vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. The specified VPN must already exist.

Usage guidelines

With a VPN instance specified, the undo apply access-vpn vpn-instance command removes the VPN instance.

Without any VPN instance specified, the undo apply access-vpn vpn-instance command removes all VPN instances.

Examples

# Set VPN 1 and VPN 2 for node 10. (VPN 1 and VPN 2 already exist.)

<Sysname> system-view

[Sysname] ipv6 policy-based-route policy1 permit node 10

[Sysname-pbr6-policy1-10] apply access-vpn vpn-instance vpn1 vpn2

apply next-hop

Use apply next-hop to set a next hop.

Use undo apply next-hop to remove the configuration.

Syntax

apply next-hop [ vpn-instance vpn-instance-name | inbound-vpn ] { ipv6-address [ direct ] [ track track-entry-number ] } &<1-2>

undo apply next-hop [ [ vpn-instance vpn-instance-name | inbound-vpn ] ipv6-address&<1-2> ]

Default

No next hop is set.

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. The specified VPN must already exist.

inbound-vpn: Specifies the VPN instance where the inbound interface belongs.

ipv6-address: Specifies the IPv6 address of the next hop. If you do not specify the vpn-instance vpn-instance-name option or the inbound-vpn keyword, the default next hop belongs to the public network.

direct: Specifies that the next hop must be directly connected to take effect.

track track-entry-number: Specifies a track entry by its number in the range of 1 to 1024.

&<1-2>: Indicates that the argument before it can be entered twice at most.

Usage guidelines

You can specify at most two next hops for backup in one command line or by executing this command twice. The first next hop configured is the active next hop and the second is the standby next hop.

With two next hops specified, only the active next hop takes effect. When the active next hop is not available, the standby next hop takes effect. When neither next hop is available, packets are forwarded according to the routing table.

With a next hop specified, the undo apply next-hop command removes the next hop.

Without any next hop specified, the undo apply next-hop command removes all next hops.

Examples

# Set a directly-connected next hop of 1::1.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 11

[Sysname-pbr6-aa-11] apply next-hop 1::1

apply output-interface

Use apply output-interface to set an output interface.

Use undo apply output-interface to remove the configuration.

Syntax

apply output-interface { interface-type interface-number [ track track-entry-number ] }

undo apply output-interface [ { interface-type interface-number } ]

Default

No output interface is set.

Parameters

interface-type interface-number: Specifies an interface by its type and number. Only null interfaces are supported.

track track-entry-number: Specifies a track entry by its number in the range of 1 to 1024.

Usage guidelines

With an output interface specified, the undo apply output-interface command removes the output interface.

Without any output interface specified, the undo apply output-interface command removes all output interfaces.

Examples

# Specify NULL 0 as the output interface for IPv6 packets.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 11

[Sysname-pbr6-aa-11] apply output-interface null 0

apply precedence

Use apply precedence to set a precedence for IPv6 packets.

Use undo apply precedence to restore the default.

Syntax

apply precedence { type | value }

undo apply precedence

Default

No precedence is set for IPv6 packets.

Table 3 Command output

Field	Description
Policy based routing information for interface Vlan-interface10(failed)	IPv6 PBR configuration and statistics on VLAN-interface 10. failed indicates the policy (including all its nodes) failed to be assigned to the driver. For a global interface (with only one-dimensional interface number, for example, VLAN-interface 10), failed can be displayed only when you specify the slot slot-number or chassis chassis-number slot slot-number option for the command.
node 0 deny(not support) node 2 permit(no resource)	Match mode of the node, permit or deny. not support means the device does not support the match criteria configured on the node. no resource means the device has insufficient ACL resources, and failed to assign ACL resources to the node. For a global interface (with only one-dimensional interface number, for example, VLAN-interface 10), not support and no resource can be displayed only when you specify the slot slot-number or chassis chassis-number slot slot-number option for the command.
if-match acl	Matches IPv6 packets against the IPv6 ACL.
apply next-hop	Specify a next hop for permitted IPv6 packets.
Matched: 0 (no statistics resource)	Number of successful matches on the node (no statistics resource indicates insufficient statistics resources). For a global interface (with only one-dimensional interface number, for example, VLAN-interface 10), no statistics resource can be displayed only when you specify the slot slot-number or chassis chassis-number slot slot-number option for the command.
Total matched	Total number of successful matches on all nodes.

ipv6 local policy-based-route

Use ipv6 local policy-based-route to configure IPv6 local PBR based on a specified policy.

Use undo ipv6 local policy-based-route to remove the configuration.

Parameters

policy-name: Specifies a policy by its name, a case-sensitive string of 1 to 19 characters. The specified IPv6 policy must already exist.

Usage guidelines

You can apply only one policy locally. Before you apply a new policy, you must first remove the current policy.

IPv6 local PBR is used to route locally generated packets. This feature might affect local services, such as ping and Telnet. Do not configure IPv6 local PBR unless doing so is required.

Examples

# Configure IPv6 local PBR based on policy aaa.

<Sysname> system-view

[Sysname] ipv6 local policy-based-route aaa

Parameters

policy-name: Specifies a policy by its name, a case-sensitive string of 1 to 19 characters. The specified policy must already exist.

Usage guidelines

You can apply only one policy to an interface. Before you apply a new policy, remove the current policy from the interface.

Examples

# Apply policy aaa to VLAN-interface 2.

[Sysname] vlan 2

[Sysname-Vlan2] interface vlan-interface 2

ipv6 policy-based-route (system view)

Use ipv6 policy-based-route to create an IPv6 policy or policy node and enter IPv6 policy node view. If the specified IPv6 policy node already exists, the command directly places you into IPv6 policy node view.

Use undo ipv6 policy-based-route to remove an IPv6 policy or IPv6 policy node.

Syntax

ipv6 policy-based-route policy-name [ deny | permit ] node node-number

undo ipv6 policy-based-route policy-name [ deny | node node-number | permit ]

Parameters

policy-name: Specifies a policy name, a case-sensitive string of 1 to 19 characters.

deny: Specifies the match mode for the policy node as deny.

permit: Specifies the match mode for the policy node as permit (default mode).

node node-number: Specifies the number of the IPv6 policy node. A smaller number has a higher priority.

Usage guidelines

To remove an IPv6 policy that has already applied to an interface, you must remove the policy from the interface first.

If a policy node is specified, the undo ipv6 policy-based-route command removes the specified policy node. If a match mode is specified, the command removes all nodes configured with the match mode. If no node is specified, the command removes the whole policy.

Examples

# Create permit-mode Node 10 for IPv6 policy aaa and enter IPv6 policy node view.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aaa permit node 10

[Sysname-pbr6-aaa-10]

Parameters

policy policy-name: Specifies a policy by its name, a case-sensitive string of 1 to 19 characters.

Usage guidelines
