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

The LSP must be shut down 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.

Parameters

lsp-name

Specifies the name that identifies the LSP, up to 32 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 configures the label to be pushed on 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 values 16 through 31 are reserved for the system.

Label values 32 through 1,023 are available for static assignment.

Label values 1,024 through 2,047 are reserved for future use.

Label values 2,048 through 18,431 are statically assigned for services.

Label values 28,672 through 131,071 are dynamically assigned for both MPLS and services.

Label values 131,072 through 1,048,575 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 the ARP for the configured next hop. The Software continuously tries the ARP for the configured next hop at a fixed interval.

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 specifies the system IP address of the egress router for the static LSP. When creating an LSP, this command is required. 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.
