The affinity of an MPLS TE tunnel is configured at the first node on the tunnel and then signaled to the rest
nodes through RSVP-TE.
NOTE:
The associations between administrative groups and affinities may vary by vendor. To ensure the
successful establishment of a tunnel between two devices from different vendors, correctly configure their
respective administrative groups and affinities.
Follow these steps to configure the administrative group and affinity attribute:
To do… Use the command... Remarks
Enter system view system-view ––
Enter interface view of MPLS TE link

Configuring CR-LSP reoptimization
Dynamic CR-LSP optimization involves the periodic calculation of paths that traffic trunks traverse. If a
better route is found for an existing CR-LSP, a new CR-LSP is established to replace the old one, and
services are switched to the new CR-LSP.
Follow these steps to configure CR-LSP reoptimization:
To do… Use the command... Remarks
Enter system view system-view ––
Enter MPLS TE tunnel interface view interface tunnel tunnel-number ––
Enable reoptimization for the MPLS TE
