Static LSP commands

static-lsp

Syntax

[no] static-lsp lsp-name

Context

config>router>mpls

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures a static LSP on the ingress router. The static LSP is a manually set up LSP where the next-hop IP address and the outgoing label (push) must be specified.

The LSP must be shut down first to delete it. If the LSP is not shut down, the no static-lsp lsp-name command does nothing except generate a warning message on the console indicating that the LSP is administratively up.

The no form of this command deletes this static LSP and associated information.

Parameters

lsp-name

Specifies the name that identifies the LSP, up to 32 alphanumeric characters.

push

Syntax

push label nexthop ip-address

no push label

Context

config>router>mpls>static-lsp

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command specifies the label to be pushed onto the label stack and the next-hop IP address for the static LSP.

The no form of this command removes the association of the label to push for the static LSP.

Parameters

label

Specifies the label to push on the label stack. Label values 16 through 1,048,575 are defined as follows.

  • Label values16 through 31 are reserved.

  • Label values 32 through 1023 are available for static assignment.

  • Label values 1024 through 2047 are reserved for future use.

  • Label values 2048 through 18431 are statically assigned for services.

  • Label values 28672 through 131071 are dynamically assigned for both MPLS and services.

  • Label values 131072 through 1048575 are reserved for future use.

Values

16 to 1048575

nexthop ip-address

Specifies the IP address of the next hop toward the LSP egress router. If an ARP entry for the next hop exists, the static LSP is marked operational. If an ARP entry does not exist, the software sets the operational status of the static LSP to down and continues to send an ARP request for the configured next hop at fixed intervals.

shutdown

Syntax

[no] shutdown

Context

config>router>mpls>static-lsp

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command administratively disables the static LSP.

The no form of this command administratively enables the static LSP.

Default

shutdown

to

Syntax

to ip-address

Context

config>router>mpls>static-lsp

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the system IP address of the egress router for the static LSP. This command is required when creating an LSP. For LSPs that are used as transport tunnels for services, the to IP address must be the system IP address.

Parameters

ip-address

Specifies the system IP address of the egress router.
