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.

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: Applies the IPv6 policy in resource sharing mode. In this mode, all interfaces on an interface card with the same IPv6 policy applied share one hardware resource. If you do not specify this keyword, each interface occupies one independent hardware resource. You can apply only one ACL, QoS policy, or PBR policy with the share-mode keyword specified to one direction of an interface. For information about ACL and QoS policies, see ACL commands and QoS policy commands in ACL and QoS Command Reference.

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 on different interfaces of the card to use the same hardware resources.

You can apply only one policy to an interface. Before you apply a new policy, remove the current policy from the interface.

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.

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.
