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:
To do...
Enter system view
Enter MPLS TE tunnel interface
view
Enable reoptimization for the
MPLS TE tunnel
Submit current tunnel
configuration
Exit to user view
Perform reoptimization on all
MPLS TE tunnels with
reoptimization enabled
This section only covers the configuration tasks for tuning MPLS TE tunnel setup.
The configurations described in this section need to be used together with the
dynamic signaling protocol CR-LDP or RSVP-TE.
Before performing them, be aware of each configuration objective and its impact
on your system.
Tuning MPLS TE tunnel setup involves these tasks:
