The mpls te reverse-lsp command configures a reverse CR-LSP for a tunnel on a specified tunnel interface.
The undo mpls te reverse-lsp command tears down a reverse CR-LSP for a tunnel on a specified tunnel interface.
By default, no reverse CR-LSP is specified in a tunnel interface view.
| Parameter | Description | Value |
|---|---|---|
| ingress-lsr-id ingress-lsr-id |
Specifies the ingress LSR ID of a reverse CR-LSP. |
The value is in dotted decimal notation. |
| tunnel-id tunnel-id |
Specifies the tunnel ID of a reverse CR-LSP. |
The value is an integer ranging from 1 to 65535. |
| protocol |
Reverse LSP protocol. |
- |
| static |
Indicates that the protocol type is set to static for a reverse CR-LSP on a specified tunnel interface. |
- |
| lsp-name lsp-name |
Specifies the name of a reverse CR-LSP. |
The value is a string of 1 to 35 case-insensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
| rsvp-te |
Indicates the type of a protocol based on which the reverse CR-LSP is established. |
- |
Usage Scenario
The tunnel-id must be configured before committing the tunnel configuration, or it will fail to create tunnel.
Precautions
When the label to be advertised is explicit-null and implicit-null, run the mpls te reverse-lsp command to specify a reverse RSVP-TE LSP function fails. After the undo mpls te reverse-lsp command is run, the reverse LSP in a bidirectional co-routed LSP in a protection tunnel group is torn down. As a result, the protection tunnel group becomes unavailable.
