The mpls te affinity property command configures the affinity property for an MPLS TE tunnel.
The undo mpls te affinity property command restores the default settings.
By default, both the affinity value and the affinity mask are 0x0 for an MPLS TE tunnel.

| Parameter | Description | Value |
|---|---|---|
| properties | Specifies the affinity property of links that carry a tunnel. | The value is in hexadecimal notation and is of 32 bits with each bit representing an attribute. The value ranges from 0x0 to 0xFFFFFFFF. The default value is 0x0. |
| mask mask-value | Specifies the link property to be checked. | The value is in hexadecimal notation and is of 32 bits with each bit representing an attribute. The value ranges from 0x0 to 0xFFFFFFFF. The default value is 0x0. |
| secondary | Indicates the affinity property of a backup CR-LSP. | - |
| best-effort | Indicates the affinity property of the best-effort path. | - |
Affinity property masks determine the link properties that should be checked by a device.
To ensure that a link can be used by a tunnel, for the bits that are 1 in a mask, it is required that at least one bit in the administrative group and the corresponding bit in the affinity property be 1. In addition, if the bits in the affinity property are 0, the corresponding bits in the administrative group cannot be 1.
After an affinity property for the MPLS TE tunnel is changed and the new configuration is committed, the established LSPs can be affected, and the path of the TE tunnel is recalculated.
