Configuring Cr-Lsp Reoptimization - HP 10500 SERIES Configuration Manual

Suppose the affinity of an MPLS TE tunnel is 0xFFFFFFFF and the mask is 0x0000FFFF. For a link to be
used by the tunnel, the leftmost 16 bits of its administrative group attribute can be 0s or 1s, but at least
one of the rest bits must be 1.
The affinity of an MPLS TE tunnel is configured at the first node on the tunnel and then signaled to the rest
of the nodes through RSVP-TE.
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.
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
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.
