Usage Guidelines

Usage Scenario

An affinity property is a 32-bit vector representing a tunnel link. You can name each affinity bit. After an affinity is configured for a tunnel, a device compares the affinity with the administrative group attribute during link selection to determine whether a link with specified attributes is selected or not. You can configure affinities for the primary CR-LSP, backup CR-LSP, and best-effort path in a tunnel.

Prerequisites

MPLS TE has been configured as a tunnel protocol using the tunnel-protocol mpls te command.

Mappings between names and bit values in an affinity have been configured using the attribute command.

Example

# Configure an affinity for the primary CR-LSP on a tunnel interface Tunnel1.
