Configuring Cr-Lsp Reoptimization; Tuning Mpls Te Tunnel Setup - HP HSR6800 Configuration Manual

The associations between administrative groups and affinities might 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.
To configure the administrative group and affinity attribute:
Step
1. Enter system view.
2. Enter interface view of MPLS
TE link.
3. Assign the link to a link
administrative group.
4. Exit to system view.
5. Enter MPLS TE tunnel
interface view.
6. Configure the affinity
attribute of the MPLS TE
tunnel.
7. Submit current tunnel
configuration.

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:
Step
1. Enter system view.
2. Enter MPLS TE tunnel interface view.
3. Enable reoptimization for the MPLS
TE tunnel.
4. Submit current tunnel configuration.
5. Return to user view.
6. Perform reoptimization on all MPLS
TE tunnels with reoptimization
enabled.

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.
