The mpls te auto-frr command enables the Auto FRR function in the interface view.
The undo mpls te auto-frr command disables the Auto FRR function in the interface view.
By default, the interface uses the configuration of the Auto FRR function in the MPLS view.
| Parameter | Description | Value |
|---|---|---|
| default |
Indicates that the interface uses the default configuration of the Auto FRR function in the MPLS view. |
- |
| link |
Indicates that only link protection is provided. |
- |
| node |
Indicates that only node protection is provided. |
- |
| self-adapting |
Enables the dynamic adaptation in Auto FRR. |
- |
| block |
Disables the Auto FRR function on the current interface. |

Usage Scenario
The mpls te auto-frr command is used to allow a device to automatically establish a bypass tunnel to protect a primary tunnel.
To establish a bypass tunnel manually, run the mpls te bypass-tunnel and mpls te protected-interface commands. NOTE: Auto FRR configured on an interface takes precedence over global Auto FRR. To enable an automatic bypass tunnel to dynamically select the node protection or link protection based on network conditions, configure self-adapting.Prerequisites
MPLS TE has been enabled globally and on the interface.
