Configuring CR-LSP reoptimization
Dynamic CR-LSP optimization involves periodic calculation of paths that traffic trunks should traverse.
If a better route is found for an existing CR-LSP, a new CR-LSP will be established to replace the old
one, and services will be switched to the new CR-LSP.
Follow these steps to configure CR-LSP reoptimization:
