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.
To configure CR-LSP reoptimization:

Tuning MPLS TE tunnel setup
This section only covers the configuration tasks for tuning MPLS TE tunnel setup.
The configurations described in this section must be used together with a dynamic signaling protocol
(such as RSVP-TE).
Before performing them, be aware of each configuration objective and its impact on your system.
