IPv6 policy-based routing commands

apply access-vpn vpn-instance

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

Use undo apply access-vpn vpn-instance to remove VPN instances.

Syntax

apply access-vpn vpn-instance vpn-instance-name&<1-n>

undo apply access-vpn vpn-instance [ vpn-instance-name&<1-n> ]

Default

No VPN instances are specified for a node.

network-admin

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.

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

Usage guidelines

You can specify a maximum of n VPN instances for a node. The matching packets are forwarded according to the forwarding table of the first available VPN instance.

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 remark-vpn

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.

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 access-vpn vpn-instance

¡     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, packets cannot be forwarded in the specified VPN instance, 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 [ vpn-instance vpn-instance-name | inbound-vpn ] { ipv6-address [ direct ] [ track track-entry-number ] }&<1-n>

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

Default

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 instance must already exist.

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

ipv6-address: Specifies the IPv6 address of the default 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 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 the argument before it can be entered up to n 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-n>

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

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-n>: Indicates that the argument before it can be entered up to n 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 GigabitEthernet 0/0/1 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 gigabitethernet 0/0/1

apply loadshare

apply default-srv6-policy

Use apply default-srv6-policy to set default SRv6 TE policies.

Use undo apply default-srv6-policy to remove default SRv6 TE policies.

Syntax

apply default-srv6-policy { endpoint color [ { sid | vpnsid } sid ] }&<1-2>

undo apply default-srv6-policy [ { endpoint color }&<1-2> ]

Default

No default SRv6 TE policies are set.

Parameters

endpoint: Specifies a default SRv6 TE policy by its endpoint IPv6 address.

color: Specifies a default SRv6 TE policy by its color attribute value in the range of 0 to 4294967295.

sid: Indicates that the SRv6 SID of the destination node is a public network SID.

vpnsid: Indicates that the SRv6 SID of the destination node is a VPN SID.

sid: Specifies the SRv6 SID of the destination node in IPv6 address format.

&<1-2>: Indicates that you can specify up to two default SRv6 TE policies.

Usage guidelines

You can specify multiple default SRv6 TE policies for backup in one command line or by executing this command multiple times. The first available default SRv6 TE policy selected according to configuration order will be used to forward matching packets.

Without any default SRv6 TE policy specified, the undo apply default-srv6-policy command removes all default SRv6 TE policies.

Use the { sid | vpnsid } sid option on the source node to specify the SRv6 SID of the destination node and its attribute information (public network SID or VPN SID). The attribute information is not encapsulated in packets and does not affect packet forwarding.

When encapsulating packets matching the default SRv6 TE policy, the source node adds the SRv6 SID of the destination node to the SRH header of the packets. The SRv6 SID is added after the SID list of the default SRv6 TE policy. Upon receiving the packets forwarded based on the default SRv6 TE policy, the destination node uses the specified SRv6 SID to perform an SRv6 local SID forwarding table lookup to forward the packets.

Examples

# Specify a default SRv6 TE policy with destination node IPv6 address 1000::1, color attribute value 10, and destination node SRv6 SID 2000::2.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 1

[Sysname-pbr6-aa-1] apply default-srv6-policy 1000::1 10 sid 2000::2

apply loadshare

Use apply loadshare to enable load sharing among multiple next hops, SRv6 TE policies, default SRv6 TE policies, 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 | default-srv6-policy | next-hop | output-interface | srv6-policy }

undo apply loadshare { default-next-hop | default-output-interface | default-srv6-policy | next-hop | output-interface | srv6-policy }

Default

Multiple next hops, output interfaces, default next hops, SRv6 TE policies, default SRv6 TE policies, 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.

default-srv6-policy: Enables load sharing among multiple default SRv6 TE policies.

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

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

srv6-policy: Enables load sharing among multiple SRv6 TE policies.

Usage guidelines

Multiple next hop, output interface, SRv6 TE policy, default next hop, default output interface, or default SRv6 TE policy 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.

Predefined user roles

network-admin

Usage guidelines

VPN remark action marks the matching packets as belonging to the VPN instance to which they are forwarded based on the apply access-vpn vpn-instance command. All subsequent service modules of IPv6 PBR handle the packets as belonging to the re-marked VPN instance.

If the VPN remark action is not enabled, the forwarded matching packets are marked as belonging to the VPN instance or the public network from which they were received.

VPN remark action applies only to packets that have been successfully forwarded based on the apply access-vpn vpn-instance command.

Examples

# Forward packets that match ACL 3000 based on the forwarding table of VPN instance vpn1 and perform VPN remark action on the successfully forwarded packets.

<Sysname> system-view

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

[Sysname-pbr6-aaa-10] if-match acl 3000

Parameters

endpoint: Specifies an SRv6 TE policy by its endpoint IPv6 address.

color: Specifies an SRv6 TE policy by its color attribute value in the range of 0 to 4294967295.

sid: Indicates that the SRv6 SID of the destination node is a public network SID.

vpnsid: Indicates that the SRv6 SID of the destination node is a VPN SID.

sid: Specifies the SRv6 SID of the destination node in IPv6 address format.

&<1-2>: Indicates that you can specify up to two SRv6 TE policies.

Usage guidelines

You can specify multiple SRv6 TE policies for backup in one command line or by executing this command multiple times. The first available SRv6 TE policy selected according to configuration order will be used to forward matching packets.

Without any SRv6 TE policy specified, the undo apply srv6-policy command removes all SRv6 TE policies.

Use the { sid | vpnsid } sid option on the source node to specify the SRv6 SID of the destination node and its attribute information (public network SID or VPN SID). The attribute information is not encapsulated in packets and does not affect packet forwarding.

When encapsulating packets matching the SRv6 TE policy, the source node adds the SRv6 SID of the destination node to the SRH header of the packets. The SRv6 SID is added after the SID list of the SRv6 TE policy. Upon receiving the packets forwarded based on the SRv6 TE policy, the destination node uses the specified SRv6 SID to perform an SRv6 local SID forwarding table lookup to forward the packets.

Examples

# Specify an SRv6 TE policy with destination node IPv6 address 1000::1, color attribute value 10, and destination node SRv6 SID 2000::2.

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

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.

apply srv6-policy 1000::1 10 sid 2000::2(NID: 2150629377)

Views

IPv6 policy node view

Predefined user roles

network-admin

Parameters

ipv6-acl-number: Specifies an IPv6 ACL by its number in the range of 2000 to 3999. The value range of a basic ACL is 2000 to 2999 and that of an advanced ACL is 3000 to 3999.

name ipv6-acl-name: Specifies an IPv6 ACL by its name, a case-insensitive string of 1 to 63 characters starting with a letter. The ACL name cannot be all. For the command to take effect, make sure the specified IPv6 ACL is a basic or advanced ACL.

Usage guidelines

If the specified ACL does not exist or has no rules configured, no packets will match the ACL.

Examples

# Configure Node 10 of policy aa to permit the packets matching ACL 2000.

<Sysname> system-view

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

[Sysname-pbr6-aa-10] if-match acl 2000

# Configure Node 10 of policy aa to permit the packets matching ACL aaa.

network-admin

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 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

System view

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 policy-based-route

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.

Views

System view

Predefined user roles

network-admin

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

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

Syntax

ipv6 policy-based-route policy-name [ share-mode ]

undo ipv6 policy-based-route

Default

No IPv6 is applied to an interface.

Views

Interface view

Predefined user roles

network-admin

Parameters

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

share-mode: Sets the resource sharing mode for the policy. An IPv6 policy in this mode uses the same hardware resources on different interfaces of a card. If you do not specify this keyword, the policy uses different hardware resources.

Usage guidelines

Typically, an IPv6 policy on different interfaces of a card uses different hardware resources. To avoid resource usage overhead, you can set the resource sharing mode when applying the policy to each interface. This mode allows the policy to use the same hardware resources on different interfaces of the card.

You can set only one mode for the policy on an interface. Before you change the mode of the policy, you must first remove the current policy from the interface.

Examples

# Apply policy aaa to GigabitEthernet 0/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 0/0/1

[Sysname-GigabitEthernet0/0/1] ipv6 policy-based-route aaa

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.

Views

System view

Predefined user roles

network-admin

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 varies by device model.

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]
