The mpls te auto-frr attributes affinity command configures an affinity for a bypass tunnel.
The undo mpls te auto-frr attributes affinity command deletes an affinity for a bypass tunnel.
By default, no affinity is configured for a bypass tunnel.

| Parameter | Description | Value |
|---|---|---|
| bandwidth bandwidth |
Specifies the bandwidth value for a bypass tunnel. |
The value is an integer ranging from 0 to 4000000000, and the actual maximum value is the maximum reservable bandwidth of a primary tunnel, in kbit/s. After bandwidth protection is enabled, the default bypass tunnel bandwidth is equal to the primary tunnel bandwidth. |
| priority setup-priority |
Specifies the setup priority. |
The value is an integer ranging from 0 to 7. The smaller the value, the higher the priority. The default setup priority is 7. |
| hold-priority |
Specifies the holding priority. |
The value is an integer ranging from 0 to 7. The smaller the value, the higher the priority. The default holding priority is 7. |
| hop-limit hop-limit-value |
Specifies the hop limit value. |
The value is an integer ranging from 1 to 32. |
| affinity |
Specify affinity parameters. |
- |
| property properties |
Specifies the affinity value of a bypass tunnel. |
The value ranges from 0x0 to 0xffffffff, in hexadecimal notation. The default value is 0x0. |
| mask mask-value |
Specifies the mask for an affinity, which is used to determine which link attributes to be checked during path selection for a tunnel. |
The 32-bit value ranges from 0x0 to 0xFFFFFFFF, each bit in which represents a property. The default value is 0x0. |
| include-all |
Allows CSPF to include a link when calculating a path, only if each link administrative group bit has the same name as each affinity bit. |
- |
| include-any |
Allows CSPF to include a link when calculating a path, if at least one link administrative group bit has the same name as an affinity bit. |
- |
| exclude |
Allows CSPF to exclude a link when calculating a path, if any link administrative group bit has the same name as an affinity bit. |
- |
| bit-name |
Specifies the referenced affinity names. |
The value is a string of 1 to 31 case-sensitive characters, spaces not supported. |

Usage Scenario
If an affinity of an automatic bypass tunnel is changed, a node starts the make-before-break mechanism to reestablish the primary tunnel and checks the binding between the primary and automatic bypass tunnels.
Prerequisites
MPLS and MPLS TE have been enabled using the mpls and mpls te commands, respectively.
Configuration Impact
If an affinity of an automatic bypass tunnel is changed, a node starts the make-before-break mechanism to reestablish the primary tunnel and checks the binding between the primary and automatic bypass tunnels.
Precautions
The mpls te auto-frr attributes command is configured on the interface of the primary tunnel; the mpls te auto-frr attributes affinity command is configured on the interface of the bypass tunnel.
With an affinity configured, if an automatic bypass tunnel that satisfies the specified affinity cannot be established, a node will bind a manual bypass tunnel satisfying the affinity to the primary tunnel.
