nexthop

Use nexthop to add or modify a node in an explicit path, and configure the attributes of the node.

Use undo nexthop to delete a node in an explicit path.

Syntax

nexthop [ index index-number ] ip-address [ exclude | include [ loose | strict ] ]

undo nexthop index index-number

Default

An explicit path does not include any nodes.

Views

Explicit path view

Predefined user roles

network-admin

Parameters

index index-number: Specifies an index for the node in the explicit path, in the range of 1 to 65535. If you do not specify an index, MPLS TE automatically calculates an index for the node, the value of which is the current maximum index value plus 100.

ip-address: Specifies a node by its IP address in dotted decimal notation.

exclude: Excludes the specified node from the explicit path.

include: Includes the specified node on the explicit path.

loose: Specifies the node as a loose node, which means the specified node and its previous hop can be indirectly connected.

strict: Specifies the node as a strict node, which means the node and its previous hop must be directly connected.

Usage guidelines

The IP address specified in this command can be one of the following:

The address of a strict node must be a link IP address. The address of a loose node can be a link IP address or the device LSR ID.

CSPF excludes the links or devices specified by exclude from path calculation, and uses the links specified by include in ascending order of indexes to establish a CRLSP.

When you execute the nexthop command, follow these guidelines:

Examples

# Exclude IP address 10.0.0.125 from MPLS TE explicit path path1.

<Sysname> system-view
[Sysname] explicit-path path1
[Sysname-explicit-path-path1] next-hop 10.0.0.125 exclude
