apply next-hop

Use apply next-hop to set a next hop.

Use undo apply next-hop to remove the configuration.

Syntax

apply next-hop [ vpn-instance vpn-instance-name ] { ipv6-address [ direct ] [ track track-entry-number ] } &<1-2>

undo apply next-hop [ [ vpn-instance vpn-instance-name ] { ipv6-address }&<1-2> ]

Default

No next hop is set.

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN by its name, a case-sensitive string of 1 to 31 characters. The specified VPN must already exist. If no VPN is specified, the next hop belongs to the public network.

ipv6-address: Specifies the next-hop IPv6 address.

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

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

&<1-2>: Indicates that the argument before it can be entered twice at most.

Usage guidelines

To configure two next hops for a policy node, you can enter two next hops in one command line or execute the command twice. The first next hop configured is the active next hop and the second is the standby next hop. With two next hops specified, only the active next hop takes effect. When the active next hop is not available, the standby next hop takes effect. When neither next hop is available, packets are forwarded according to the routing table.

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.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 11

[Sysname-pbr6-aa-11] apply next-hop 1::1

Table 2 Command output

Field	Description
Policy based routing information for interface GigabitEthernet3/0/1(failed)	IPv6 PBR configuration and statistics on GigabitEthernet 3/0/1. failed indicates the policy (including all its nodes) failed to be assigned to the driver. For a global interface (with only one-dimensional interface number, for example, VLAN-interface 10), failed can be displayed only when you specify the slot slot-number or chassis chassis-number slot slot-number option for the command.
node 0 deny(not support) node 2 permit(no resource)	Match mode of the node, permit or deny. not support means the device does not support the match criteria configured on the node. no resource means the device has insufficient ACL resources, and failed to assign ACL resources to the node. For a global interface (with only one-dimensional interface number, for example, VLAN-interface 10), not support and no resource can be displayed only when you specify the slot slot-number or chassis chassis-number slot slot-number option for the command.
if-match acl	Matches IPv6 packets against the IPv6 ACL.
apply next-hop	Specify a next hop for permitted IPv6 packets.
Matched: 0 (no statistics resource)	Number of successful matches on the node (no statistics resource indicates insufficient statistics resources). For a global interface (with only one-dimensional interface number, for example, VLAN-interface 10), no statistics resource can be displayed only when you specify the slot slot-number or chassis chassis-number slot slot-number option for the command.
Total matched	Total number of successful matches on all nodes.

Parameters

acl-number: Specifies an 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.

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

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

Examples

# Apply policy aaa on VLAN-interface 2.

[Sysname] vlan 2

[Sysname-Vlan2] interface vlan-interface 2

ipv6 policy-based-route (system view)

Use ipv6 policy-based-route to create an IPv6 policy or policy node and enter IPv6 policy node view. If the specified IPv6 policy node already exists, the command directly places you into IPv6 policy node view.

Use undo ipv6 policy-based-route to remove 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 ]

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, in the range of 0 to 65535. A smaller number has a higher priority.

Usage guidelines

To remove an IPv6 policy that has already applied to an interface, you must remove the policy from the interface first.

If a policy node is specified, the undo ipv6 policy-based-route command removes the specified policy node. If a match mode is specified, the command removes all nodes configured with the match mode. If no node is specified, the command removes the whole policy.

Examples

# Create permit-mode Node 10 for IPv6 policy aaa and enter IPv6 policy node view.

<Sysname> system-view

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

[Sysname-pbr6-aaa-10]
