113Suppose the affinity of an MPLS TE tunnel is 0xFFFFFFFF and the mask is 0x0000FFFF. For a link to beused by the tunnel, the leftmost 16 bits of its administrative group attribute can be 0s or 1s, but at leastone of the rest bits must be 1.The affinity of an MPLS TE tunnel is configured at the first node on the tunnel and then signaled to the restnodes through RSVP-TE.NOTE:The associations between administrative groups and affinities may vary by vendor. To ensure thesuccessful establishment of a tunnel between two devices from different vendors, correctly configure theirrespective administrative groups and affinities.To configure the administrative group and affinity attribute:Step Command Remarks1. Enter system view. system-view N/A2. Enter interface view of MPLSTE link.interface interface-typeinterface-number N/A3.

If abetter route is found for an existing CR-LSP, a new CR-LSP is established to replace the old one, andservices are switched to the new CR-LSP.To configure CR-LSP reoptimization:Step Command Remarks1.
