static-cr-lsp transit
Function
The static-cr-lsp transit command configures a static CR-LSP on a transit LSR.
The undo static-cr-lsp transit command deletes a static CR-LSP from the transit LSR.
By default, no static CR-LSP on a transit LSR is configured.
Format
static-cr-lsp transit lsp-name [ incoming-interface interface-type interface-number ] in-label in-label { nexthop next-hop-address | outgoing-interface interface-type interface-number } * out-label out-label [ bandwidth [ ct0 | ct1 ] bandwidth ] [ description description ]
undo static-cr-lsp transit lsp-name
Parameters
| Parameter | Description | Value |
|---|---|---|
| lsp-name | Specifies the CR-LSP name. | The value is a string of 1 to 19 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
| incoming-interface interface-type interface-number | Specifies the incoming interface of the CR-LSP.
|
- |
| in-label in-label | Specifies the value of an incoming label. | The value is an integer that ranges from 16 to 1023. |
| nexthop next-hop-address | Specifies the next-hop address. | The value is in dotted decimal notation. |
| outgoing-interface interface-type interface-number | Specifies the name of an outgoing interface. | - |
| out-label out-label | Specifies the value of an outgoing label. | The value is an integer that ranges from 16 to 1048575. |
| bandwidth [ ct0 | ct1 ] bandwidth | Specifies the bandwidth values of CR-LSPs of CT0 to CT1. |
The value is an integer ranges from 0 to 4000000000, in kbit/s. The default value is 0. |
| description description | Specifies the description information. | The value is a string of 1 to 63 case-sensitive characters with spaces. |
Usage Guidelines
Before setting up an MPLS TE tunnel through a static CR-LSP, configure a static route or an IGP to ensure connectivity between LSRs, and enable basic MPLS and MPLS TE functions. After setting up a static CR-LSP, you can run the display mpls static-cr-lsp command to ensure that the static CR-LSP is established successfully.
To modify parameters including incoming-interface interface-type interface-number, in-label in-label, nexthop next-hop-address, outgoing-interface interface-type interface-number, and out-label out-label, run the static-cr-lsp transit command to set a new value for each parameter. There is no need to run the undo static-cr-lsp transit command before modifying a value.
The configured bandwidth takes effect only during tunnel establishment and protocol negotiation, and does not limit the bandwidth for traffic forwarding. (S5720-HI does not have this restriction.)
Example
# Configure the static CR-LSP named tunnel39 with the incoming interface being VLANIF100, the incoming label being 123, the outgoing interface being VLANIF200, the outgoing label as 253.
