4000 Router Series MPLS Command Reference

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

connected indirectly.

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:

• Link IP address—IP address of an interface on the device, identifying a link.

• Device LSR ID—Identifies the device.

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, note the following guidelines:

• If you specify an existing index, the command modifies the IP address or attribute of the node

identified by that index.

• If you specify neither include nor exclude, the include keyword is used by default.

• If you specify neither loose nor strict, the strict keyword is used by default.

Examples

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

<Sysname> system-view

[Sysname] explicit-path path1

[Sysname-explicit-path-path1] next-hop 10.0.0.125 exclude

path-metric-type

Use path-metric-type to specify the link metric type to be used for path selection when a metric type is not

explicitly specified for a tunnel.

Use undo path-metric-type to restore the default.
