Usage guidelines

If you do not specify any parameters, this command displays information about all static prefix segments.

Table 2 Command output

Field

Description

Prefix Name

Name of the prefix segment.

Destination

Destination IP address of the prefix segment.

In-Label

Incoming label of the prefix segment.

Active

Status of the prefix segment:

·     Yes(count)—The prefix segment is active. The value of count represents the number of egresses in up status.

·     No—The prefix segment is inactive.

Out-Interface

Outgoing interface of the prefix segment.

Nexthop

Next hop of the prefix segment.

Out-Label

Outgoing label of the prefix segment.

Status

Status of the egress:

·     down—The egress is inactive. The cause is displayed in brackets, which can be No Route or No Mpls. No Route means that the device has no route to reach the destination IP address over the outgoing interface. No Mpls means that MPLS is disabled on the output interface.

·     up—The egress is active.

·     duplicate—An egress conflict has occurred because the output interface is already used by another prefix segment.

static-sr-mpls adjacency

Use static-sr-mpls adjacency to configure an adjacency segment for static MPLS SR.

Use undo static-sr-mpls adjacency to delete an adjacency segment.

Syntax

static-sr-mpls adjacency adjacency-path-name in-label label-value { nexthop ip-address | outgoing-interface interface-type interface-number }

undo static-sr-mpls adjacency adjacency-path-name

Default

No adjacency segments exist.

Parameters

adjacency-path-name: Specifies the adjacency segment name, a case-sensitive string of 1 to 15 characters.

in-label label-value: Specifies the incoming label, in the range of 16 to 1023.

nexthop ip-address: Specifies the next hop address.

outgoing-interface interface-type interface-number: Specifies an output interface by its type and number. The output interface must be a P2P interface.

Usage guidelines

Execute this command on all nodes of a static SRLSP.

If you specify the next hop address, make sure the following requirements are met:

·     The device has a route to reach the next hop address.

·     MPLS is enabled on the output interface of the route.

If you specify an output interface, make sure the following requirements are met:

·     The interface is up.

·     The interface can receive direct routes.

·     MPLS is enabled on the interface.

The incoming label specified by this command must be different than existing static LSPs and static PWs. If not, the configured adjacency segment is unavailable. The adjacency segment cannot become available even if you change the incoming label of the static LSP or static PW. To resolve this problem, you must delete the existing adjacency segment and configure a new one with a different incoming label.

Examples

# Configure an adjacency segment named adj1. Set the incoming label to 100 and the next hop address to 12.2.1.2.

<Sysname> system-view

[Sysname] static-sr-mpls adjacency adj1 in-label 100 nexthop 12.2.1.2

static-sr-mpls lsp

Use undo static-sr-mpls lsp to delete a static SRLSP.

Syntax

undo static-sr-mpls lsp lsp-name

Default

No static SRLSPs exist.

Parameters

lsp-name: Specifies the static SRLSP name, a case-sensitive string of 1 to 15 characters.

out-label out-label-value&<1-4>: Specifies a space-separated list of up to 4 outgoing labels, corresponding to the labels from top to bottom in the label stack. The value range for the out-label-value argument is 0, 3, and 16 to 1048575.

Usage guidelines

Execute this command only on the ingress node of a static SRLSP.

The outgoing labels represent an ordered list of labels allocated for the adjacencies or nodes that a static SRLSP traverses. The top label is the label that the ingress node allocates for the adjacency or destination prefix.

Examples

# Configure a static SRLSP named lsp1. Specify outgoing labels 100 and 200 for the SRLSP.

<Sysname> system-view

[Sysname] static-sr-mpls lsp lsp1 out-label 100 200

static-sr-mpls prefix

Parameters

prefix-path-name: Specifies the prefix segment name, a case-sensitive string of 1 to 15 characters.

destination ip-address: Specifies the destination IP address.

mask: Specifies the mask.

mask-length: Specifies the mask length, in the range of 0 to 32.

in-label label-value: Specifies the incoming label, in the range of 16000 to 24000.

nexthop ip-address: Specifies the next hop address.

outgoing-interface interface-type interface-number: Specifies an output interface by its type and number. The output interface must be a P2P interface.

out-label out-label-value: Specifies the outgoing label, in the range of 0, 3, and 16 to 1048575.

Usage guidelines

Execute this command on all nodes of a static SRLSP.

A prefix segment must use the next hop or output interface of the optimal route to the destination address of the prefix segment. You can configure multiple prefix segments to the destination address for load sharing if the optimal route has more than one next hops or output interfaces. To avoid configuration failure, make sure all prefix segments use the same prefix segment name, and incoming label.

If you specify only the prefix-path-name argument, the undo static-sr-mpls prefix command deletes all prefix segments with the specified name. If you specify all parameters, only the prefix segment that matches the specified name, destination IP address, and next hop or output interface is deleted.

Examples

# Configure a prefix segment named prefix1. Set the destination IP address, incoming label, outgoing label, and next hop to 2.2.2.2, 16000, 16001, and 10.0.0.2, respectively.

<Sysname> system-view

[Sysname] static-sr-mpls prefix prefix1 destination 2.2.2.2 32 in-label 16000 nexthop 10.0.0.2 out-label 16001
