Policy-based routing commands

apply next-hop

Use apply next-hop to set next hops.

Use undo apply next-hop to remove next hops.

Syntax

apply next-hop [ vpn-instance vpn-instance-name ] { ip-address [ direct ] }&<1-4>

undo apply next-hop [ [ vpn-instance vpn-instance-name ] ip-address&<1-4> ]

Default

No next hops are set.

Views

Policy node view

Predefined user roles

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 next hop. If you do not specify the vpn-instance vpn-instance-name option or the inbound-vpn keyword, the next hop belongs to the public network.

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

&<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 1.1.1.1.

<Sysname> system-view

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

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

# Enable match counting on policy node 11.

<Sysname> system-view

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

[Sysname-pbr-aa-11] apply statistics

Table 3 Command output

Field	Description
Policy based routing information for interface XXXX	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. 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 node 2 permit	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 packets with the ACL.
apply next-hop	Specifies a next hop for permitted packets.
apply output-interface	Specifies an output interface and its associated track entry for permitted packets. This field displays the interface status in brackets. ·     up—The interface is up. ·     down—The interface is down at network layer. ·     inactive—The card that hosts the interface is not in position.
Matches	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. If the device does not support counting successful matches on a node, this field displays N/A. If match counting is disabled on the node, this field is not displayed. 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.
bytes	Number of matching bytes on the node. This field displays N/A if the device does not support counting matching bytes on a node. This field is not displayed if match counting is disabled on the node.
Total matches	Total number of successful matches on all nodes. This field displays N/A if the device does not support counting successful matches on a node. This field is not displayed if match counting is disabled on all nodes.
total bytes	Total number of matching bytes on all nodes. This field displays N/A if the device does not support counting matching bytes on a node. This field is not displayed if match counting is disabled on all nodes.

if-match acl

Use if-match acl to set an ACL match criterion.

Parameters

acl-number: Specifies an ACL by its number in the range of 2000 to 2999 for a basic ACL, and in the range of 3000 to 3999 for an advanced ACL.

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

If the vpn-instance keyword is specified for an ACL rule, the ACL does not take effect. If the vpn-instance keyword is not specified, the rule applies to both public and private network packets.

Examples

# Configure Node 11 of policy aa to permit the packets matching ACL 2011.

<Sysname> system-view

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

[Sysname-pbr-aa-11] if-match acl 2011

# Configure Node 11 of policy aa to permit the packets matching ACL aaa.

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

[Sysname-pbr-aa-11] if-match acl name aaa

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

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.

Examples

# Configure local PBR based on policy aaa.

<Sysname> system-view

[Sysname] ip local policy-based-route aaa

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

Parameters

policy-name: Specifies a policy by its 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 a policy node by its number. A smaller number has a higher priority. The value range for the node-number argument is 0 to 255.

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.
