Usage guidelines

This command takes effect only when the mode of the node is permit.

This command applies when either of the following conditions exist:

·     None of the following clauses is configured for packet forwarding:

¡     apply next-hop

¡     apply output-interface

¡     apply default-next-hop

¡     apply default-output-interface

·     A clause listed above is configured, but it has become invalid. Then, a routing table lookup also fails for the matching packet.

‌

NOTE: A clause might become invalid because the specified next hop is unreachable or the specified output interface is down.

‌

Examples

# Compare with the next policy node upon failure on the current node.

<Sysname> system-view

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

[Sysname-pbr6-aa-11] apply continue

apply default-next-hop

Use apply default-next-hop to set default next hops.

Use undo apply default-next-hop to remove default next hops.

Syntax

apply default-next-hop { ipv6-address [ direct ] [ track track-entry-number ] }&<1-4>

undo apply default-next-hop [ ipv6-address&<1-4> ]

Default

No default next hops are set.

Parameters

ipv6-address: Specifies the IPv6 address of the default next hop.

direct: Specifies a directly connected default next hop.

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

&<1-4>: Indicates that the argument before it can be entered up to four times.

Usage guidelines

You can specify multiple default next hops for backup or load sharing in one command line or by executing this command multiple times.

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

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

Examples

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

<Sysname> system-view

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

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

apply loadshare

apply default-output-interface

Use apply default-output-interface to set default output interfaces.

Use undo apply default-output-interface to remove default output interfaces.

Syntax

apply default-output-interface { interface-type interface-number [ track track-entry-number ] }&<1-4>

undo apply default-output-interface [ { interface-type interface-number }&<1-4> ]

Default

No default output interfaces are set.

Parameters

interface-type interface-number: Specifies an interface by its type and number.

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

&<1-4>: Indicates that the argument before it can be entered up to four times.

Usage guidelines

You can specify multiple default output interfaces for backup or load sharing in one command line or by executing this command multiple times.

The default output interface must be P2P type. Using a non-P2P default output interface can result in forwarding failures when the interface has multiple next hops. Non-P2P interfaces include broadcast and non-broadcast multi-access (NBMA) interfaces such as Ethernet and virtual-template interfaces. In NBMA networks, packets are sent in unicast.

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

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

Examples

# Specify VLAN-interface 2 as the default output interface for IPv6 packets.

<Sysname> system-view

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

[Sysname-pbr6-aa-11] apply default-output-interface vlan-interface 2

Related commands

apply loadshare

apply loadshare

Use apply loadshare to enable load sharing among multiple next hops, output interfaces, default next hops, or default output interfaces.

Use undo apply loadshare to restore the default.

Syntax

apply loadshare { default-next-hop | default-output-interface | next-hop | output-interface }

undo apply loadshare { default-next-hop | default-output-interface | next-hop | output-interface }

Default

Multiple next hops, output interfaces, default next hops, or default output interfaces operate in primary/backup mode.

Parameters

default-next-hop: Enables load sharing among multiple default next hops.

default-output-interface: Enables load sharing among multiple default output interfaces.

next-hop: Enables load sharing among multiple next hops.

output-interface: Enables load sharing among multiple output interfaces.

Usage guidelines

Multiple next hop, output interface, default next hop, or default output interface options operate in either primary/backup or load sharing mode. The following description uses multiple next hops as an example:

·     Primary/backup mode—A next hop is selected from all next hops in configuration order for packet forwarding, with all remaining next hops as backups. When the selected next hop fails, the next available next hop takes over.

·     Load sharing mode—Matching traffic is distributed across the available next hops. If the traffic does not match any fast forwarding entries, per-packet load sharing is performed. If the traffic matches a fast forwarding entry, per-flow load sharing is performed.

Examples

# Enable load sharing among multiple next hops.

<Sysname> system-view

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

[Sysname-pbr6-aa-11] apply next-hop 1::1 2::2

Parameters

ipv6-address: Specifies the IPv6 address of the next hop.

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.

weight weight-value: Specifies a load sharing weight for the next hop, in the range of 1 to 100. The default is 10. If you specify weights 1, 1, and 2 for three next hops, they share 1/4, 1/4, and 1/2 of the whole traffic, respectively.

&<1-4>: Indicates that you can repeat the previous group of parameters to configure up to four next hops.

Usage guidelines

You can specify multiple next hops for backup or load sharing in one command line or by executing this command multiple times.

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.

Parameters

min-len: Specifies the minimum IPv6 packet length in the range of 1 to 65535 bytes.

max-len: Specifies the maximum IP packet length in the range of 1 to 65535 bytes. The maximum length must be no less than the minimum length.

Usage guidelines

The packet length range includes boundary values. For example, if you set the min-len and max-len arguments to 100 and 200, respectively, packets with lengths of 100 bytes and 200 bytes are also matched.

Examples

# Match packets with a length from 100 to 200 bytes.

<Sysname> system-view

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

[Sysname-pbr6-aa-11] if-match packet-length 100 200

ipv6 global policy-based-route

Use ipv6 global policy-based-route to specify a PBR policy as the IPv6 global PBR policy.

Use undo ipv6 global policy-based-route to restore the default.

Syntax

ipv6 global policy-based-route policy-name

undo ipv6 global policy-based-route

Default

No policy is specified for IPv6 global PBR.

Views

Predefined user roles

network-admin

Parameters

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

Usage guidelines

IPv6 global PBR guides the forwarding of packets on all interfaces of the device.

You can specify only one policy for IPv6 global PBR on the device. Before you apply a new policy, you must first remove the current policy.

IPv6 interface PBR takes precedence over IPv6 global PBR on an interface. When they are both configured and packets fail to match the IPv6 interface PBR policy, IPv6 global PBR applies.

Examples

# Specify PBR policy aaa for IPv6 global PBR.

<Sysname> system-view

[Sysname] ipv6 global policy-based-route aaa

Related commands

display ipv6 policy-based-route global

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 restore the default.

Syntax

ipv6 local policy-based-route policy-name

undo ipv6 local policy-based-route

Default

No policy is referenced for IPv6 local PBR.

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 except the packets destined for the sender. This feature might affect local services. 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

Related commands

display ipv6 policy-based-route local

ipv6 policy-based-route (interface view)

Use ipv6 policy-based-route to configure IPv6 interface PBR by applying an IPv6 policy to an interface.

Use undo ipv6 policy-based-route to restore the default.

Syntax

ipv6 policy-based-route policy-name

undo ipv6 policy-based-route

Default

No IPv6 is applied to an interface.

Parameters

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

Examples

# Apply policy aaa to VLAN-interface 2.

<Sysname> system-view

[Sysname] interface vlan-interface 2

[Sysname-Vlan-interface2] ipv6 policy-based-route aaa

ipv6 policy-based-route (system view)

Use ipv6 policy-based-route to create an IPv6 policy node and enter its view, or enter the view of an existing IPv6 policy node.

Use undo ipv6 policy-based-route to delete 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 ]

Default

No IPv6 policy nodes exist.

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. The value range for the node-number argument is 0 to 255.

Usage guidelines

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

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

Examples

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

<Sysname> system-view

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

[Sysname-pbr6-aaa-10]

Syntax

ipv6 policy-based-route policy-name apply vlan-interface interface-list &<1-8>

undo ipv6 policy-based-route policy-name apply [ vlan-interface interface-list &<1-8> ]

Default

No IPv6 policy is specified for the VLAN interfaces.

Parameters

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

vlan-interface interface-list: Specifies a space-separated list of up to eight VLAN interface items. Each item specifies a VLAN interface or a range of VLAN interfaces in the form of interface-type interface-number1 to interface-type interface-number2. The value for interface-number2 must be greater than or equal to the value for interface-number1. The interface type is VLAN interface.

Usage guidelines

You cannot specify different policies for a VLAN interface. You can use either of the following commands to specify a policy for a VLAN interface:

·     ipv6 policy-based-route apply

·     ipv6 policy-based-route (interface view)

To specify an IPv6 policy for multiple VLAN interfaces, you can use either of the following methods:

·     Method 1—Execute the ip policy-based-route apply command. The policy is issued to the driver for all interfaces at the same time. This method reduces hardware entries and saves system resources. You can use this method to specify an IPv6 policy for VLAN interfaces that do not exist.

·     Method 2—Use the interface range command to create an interface range, and specify a policy for the interface range. The policy is issued to the driver for each interface. The system creates a hardware entry for each interface.

Examples

# Specify IPv6 policy aaa for VLAN-interface 100 through VLAN-interface 200.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aaa apply vlan-interface 100 to 200

Usage guidelines

After you enable this feature, IPv6 PBR can generate notifications and send them to the SNMP module when the next hop becomes invalid. For the IPv6 PBR notifications to be sent correctly, you must also configure SNMP on the device. For more information about configuring SNMP, see the network management and monitoring configuration guide for the device.

Examples

# Enable SNMP notifications for IPv6 PBR.

<Sysname> system-view

[Sysname] snmp-agent trap enable ipv6 policy-based-route
