Policy-based routing commands

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 ] { ip-address [ direct ] [ track track-entry-number ] [ service-chain path-id service-path-id [ path-index service-path-index ] ] }&<1-2>

undo apply default-next-hop [ [ vpn-instance vpn-instance-name ] ip-address&<1-2> ]

Default

No default next hops are set.

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. The specified VPN instance must already exist.

ip-address: Specifies the IP address of the default next hop. If you do not specify the vpn-instance vpn-instance-name option, 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.

service-chain path-id service-path-id: Specifies a service chain by its path ID. A path ID uniquely identifies a service chain, and its value range is 1 to 16777215.

path-index service-path-index: Specifies a node in the service chain as a default next hop by its index in the range of 1 to 255.

&<1-2>: Indicates that you can repeat the previous group of parameters to configure up to two default next hops.

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.

To set multiple default next hops and specify their service chain parameters (service chain path ID and node index), follow these guidelines:

· If the next hops are used in different service chains, use the apply default-next-hop command to specify the service chain parameters.

· If the next hops are used in the same service chain, use the apply service-chain command to specify the service chain parameters as a best practice.

· On a policy node, you cannot configure both the apply default-next-hop command with the service chain parameters and the apply service-chain command.

Examples

# Set a directly-connected default next hop of 1.1.1.1.

<Sysname> system-view

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

[Sysname-pbr-aa-11] apply default-next-hop 1.1.1.1 direct

Related commands

apply loadshare

apply service-chain

apply loadshare

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

Use undo apply loadshare to restore the default.

Syntax

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

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

Default

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

Views

Policy node view

Predefined user roles

network-admin

Parameters

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

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

Usage guidelines

Multiple next hop or default next hop options operate in either primary/backup or load sharing mode.

· 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] policy-based-route aa permit node 11

[Sysname-pbr-aa-11] apply next-hop 1.1.1.1 2.2.2.2

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

# Enable load sharing among multiple default next hops.

<Sysname> system-view

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

[Sysname-pbr-aa-11] apply default-next-hop 1.1.1.1 2.2.2.2

apply mirror-to-destination

Use apply mirror-to-destination to set a mirroring action that mirrors packets to the specified destination IP address.

Use undo apply mirror-to-destination to restore the default.

Syntax

apply mirror-to-destination [ vpn-instance vpn-instance-name ] destination-ip-address [ source-ip source-ip-address ] [ dscp dscp-value ]

undo apply mirror-to-destination [ vpn-instance vpn-instance-name ] destination-ip-address

Default

The mirroring action is not set.

Views

Policy node view

Predefined user roles

network-admin

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the destination IP address belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. The specified VPN instance must already exist. If the destination IP address belongs to the public network, do not specify this option.

destination-ip-address: Specifies the destination IP address encapsulated in the outer header of mirrored packets.

source-ip source-ip-address: Specifies the source IP address encapsulated in the outer header of mirrored packets. If you do not specify this option, the primary IP address for the output interface of the mirrored packets is encapsulated.

dscp dscp-value: Specifies the DSCP value encapsulated in the outer header of mirrored packets. The value range for the dscp-value argument is 0 to 63, and the default value is 63.

Usage guidelines

This command enables the device to mirror packets to a specific destination device through a tunnel (for example, a GRE tunnel) for packet analysis and monitoring. The device will encapsulate the parameters set for this command in the outer header of the mirrored packets.

This apply clause is always executed for packets matching the policy node in either permit or deny mode.

Examples

# Set a mirroring action by specifying source IP address 2.2.2.2 and destination IP address 1.1.1.1 in the outer header of mirrored packets.

<Sysname> system-view

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

[Sysname-pbr-aa-11] apply mirror-to-destination 1.1.1.1 source-ip 2.2.2.2

apply next-hop

Use apply next-hop to set next hops.

Use undo apply next-hop to remove next hops.

Syntax

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

service-chain path-id service-path-id: Specifies a service chain by its path ID. A path ID uniquely identifies a service chain, and its value range is 1 to 16777215.

path-index service-path-index: Specifies a node in the service chain as a next hop by its index in the range of 1 to 255.

&<1-8>: Indicates that you can repeat the previous group of parameters to configure up to eight 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.

To set multiple next hops and specify their service chain parameters (service chain path ID and node index), follow these guidelines:

network-admin

Parameters

path-id service-path-id: Specifies a service chain by its path ID in the range of 1 to 16777215. The path ID uniquely identifies a service chain.

path-index service-path-index: Specifies a node in the service chain by its index to match packets sent from that node. The value range for path indexes is 1 to 255. Specify this option if the device might receive packets from different nodes in the service chain. If only one node in the service chain sends packets to the device, you do not need to specify this option.

Examples

# Set a service chain match criterion to match packets with service chain path ID 1 and node index 10.

Default

No policy is specified for 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

Global PBR guides the forwarding of packets on all interfaces of the device.

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

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

Examples

# Specify PBR policy aaa for global PBR.

<Sysname> system-view

[Sysname] ip global policy-based-route aaa

Use undo ip ignore policy-based-route dest-local enable to restore the default.

Syntax

ip ignore policy-based-route dest-local enable

undo ip ignore policy-based-route dest-local enable

Default

PBR does not ignore IPv4 packets destined to the local interface.

Views

Interface view

Predefined user roles

network-admin

Usage guidelines

If the device performs forwarding in hardware and a packet destined for it matches a PBR policy, PBR will execute the apply clauses in the policy, including the clause for forwarding. To prevent PBR from mistakenly forwarding the packet to another device, you can configure this command in interface view. Upon receiving a packet destined to any IPv4 addresses (main or secondary) of the interface, the device will ignore PBR settings and deliver the packet to the CPU.

Examples

# Enable PBR to ignore IPv4 packets destined to local interface VLAN-interface 2.

<Sysname> system-view

[Sysname] interface vlan-interface 2

[Sysname-Vlan-interface2] ip ignore policy-based-route dest-local enable

ip local policy-based-route

Use ip local policy-based-route to specify a policy for local PBR.

Use undo ip local policy-based-route to restore the default.

Syntax

ip local policy-based-route policy-name

undo ip local policy-based-route

Default

No policy is referenced for local PBR.

Views

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.

Usage guidelines

Local PBR guides the forwarding of locally generated packets, such as ICMP packets generated by using the ping command.

Local PBR might affect local services, such as ping and Telnet. When you use local PBR, make sure you fully understand its impact on local services of the device.

You can specify only one policy for local PBR and must make sure the specified policy already exists.

Before you apply a new policy, you must first remove the current policy.

Predefined user roles

network-admin

Usage guidelines

The PBR logging feature helps the administrator locate and fix faults. The feature logs PBR events and sends the logs to the information center. The information center processes the logs according to output rules. For more information about the information center, see System Management Configuration Guide.

Excessive PBR log messages degrade the performance of the device. To avoid this problem, disable the PBR logging feature.

Examples

# Enable the PBR logging feature.

<Sysname> system-view

[Sysname] ip policy-based-route-log enable

ip policy-based-route vxlan-mode enable

Use ip policy-based-route vxlan-mode enable to enable VXLAN-mode PBR.

Use undo ip policy-based-route vxlan-mode enable to disable VXLAN-mode PBR.

Syntax

ip policy-based-route vxlan-mode enable

undo ip policy-based-route vxlan-mode enable

Default

VXLAN-mode PBR is disabled.

Views

System view

Predefined user roles

network-admin

Usage guidelines

VXLAN-mode PBR enables you to guide packets from a site-facing interface on a VXLAN VTEP to a VXLAN tunnel by using a PBR policy. If VXLAN-mode PBR is not enabled, the PBR policy on a site-facing interface cannot guide packets to a VXLAN tunnel.

Execute this command before you apply a PBR policy to a site-facing interface. This command requires updating forwarding entries, which is time-consuming and might cause inadequate table entry resources.

Examples

# Enable VXLAN-mode PBR.

<Sysname> system-view

[Sysname] ip policy-based-route vxlan-mode enable

policy-based-route

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 a policy node by its number. A smaller number has a higher priority. The value range for the node-number argument is 0 to 65535. You can configure a maximum of 256 nodes for a single policy.

Usage guidelines

A policy that has been applied to an interface or locally cannot be deleted. To delete it, you must first cancel the application.

· If a policy node is specified, the undo 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 policy node or match mode is specified, the command deletes the whole policy.

# Create permit-mode of Node 10 for policy policy1 and enter its view.
