apply continue

Use apply continue to compare packets with the next policy node upon failure on the current node.

Use undo apply continue to restore the default.

Syntax

apply continue

undo apply continue

Default

IPv6 PBR does not compare packets with the next policy node upon failure on the current node.

Views

Predefined user roles

network-admin

Usage guidelines

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

This command applies when the following clauses are not configured or become invalid:

·     apply next-hop

·     apply output-interface

·     apply default-next-hop

·     apply default-output-interface

For example, the command applies when 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-n>

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

Default

No default next hop is set.

Views

Predefined user roles

network-admin

Parameters

ipv6-address: Specifies  the IPv6 address of a 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-n>: Indicates that you can specify up to n default next hops, each of which can be associated with a track entry. The value for n varies by device model.

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

Related commands

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-n>

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

Default

No default output interface is set.

Views

IPv6 policy node view

Predefined user roles

network-admin

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-n>: Indicates that you can specify up to n interfaces, each of which can be associated with a track entry. The value for n varies by device model.

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.

Views

IPv6 policy node view

Predefined user roles

network-admin

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 hops, output interfaces, default next hops, or default output interfaces operate in either primary/backup or load sharing mode. For example:

·     Primary/backup mode—The first configured output interface is used. When the primary output interface fails, the first configured backup output interface takes over.

·     Load sharing mode—Multiple output interfaces load share traffic on a per-packet basis in turn, according to the configuration order.

 

 

NOTE:

Multiple next hops load share traffic according to their weights. By default, all next hops have the same weight and traffic is load balanced among them.

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

[Sysname-pbr6-aa-11] apply loadshare next-hop

Table 3 Command output

Field

Description

Policy based routing information for interface XXXX(failed)

IPv6 PBR configuration and statistics on the interface.

This field displays failed in brackets if none of the nodes in the policy has been successfully issued to the driver. The failed status will persist even after the policy is successfully issued. To clear the failed status, you must remove the policy from the interface and then apply it on the interface again.

NOTE:

The failed status is available on a per-slot basis. To obtain this information, you must specify a slot number when you execute the command.

·     For a global interface (for example, a VLAN interface), which might have member physical interfaces on multiple slots, specify a slot that contains its member interfaces.

·     For a physical interface, specify its slot number.

node 0 deny(not support)

node 2 permit(no resource)

Match mode of the node, permit or deny.

If a node fails to be issued to the driver, the command displays the cause in brackets, which include:

·     not support—The device does not support the match criteria configured on the node.

·     no resource—No sufficient resources (for example, ACLs) are available for the node.

NOTE:

The cause is available only on a per-slot basis. To obtain this information, you must specify a slot number when you execute the command.

·     For a global interface (for example, a VLAN interface), which might have member physical interfaces on multiple slots, specify a slot that contains its member interfaces.

·     For a physical interface, specify its slot number.

if-match acl

Compares IPv6 packets with the IPv6 ACL.

apply next-hop

Specifies a next hop for permitted IPv6 packets.

apply output-interface  track 1 (down)

Specifies an output interface for permitted packets. The interface status includes the following:

·     up—The interface is up.

·     down—The interface is down at network layer.

·     inactive—The interface is not in position.

Matched: 0 (no statistics resource)

Number of successful matches on the node. If the device does not have sufficient resources to count matches, this field displays no statistics resource in brackets.

NOTE:

The statistics collection failure cause is available only on a per-slot basis. To obtain this information, you must specify a slot number when you execute the command.

·     For a global interface (for example, a VLAN interface), which might have member physical interfaces on multiple slots, specify a slot that contains its member interfaces.

·     For a physical interface, specify its slot number.

Total matched

Total number of successful matches on all nodes.

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.
