Tuning Cr-Lsp Setup; Configuring Route Pinning; Configuring Administrative Group And Affinity Attribute - HP 10500 SERIES Configuration Manual

Step
3. Enable global RSVP hello
extension.
4. Enable MPLS RSVP-TE GR.
5. Set the RSVP-TE GR restart
timer.
6. Set the RSVP-TE GR recovery
timer.
7. Enter interface view of MPLS
TE link.
8. Enable RSVP hello extension
for the interface.

Tuning CR-LSP setup

A CR-LSP is established through the signaling protocol based on the path calculated by CSPF using TEDB
and constraints. MPLS TE can affect CSPF calculation in many ways to determine the path that a CR-LSP
can traverse.
The configuration tasks described in this section are about CSPF of MPLS TE. You must use them in
conjunction with CSPF and RSVP-TE. Before performing them, be aware of each configuration objective
and its impact on your system.

Configuring route pinning

You cannot use route pinning together with reoptimization.
To configure route pinning:
Step
1. Enter system view.
2. Enter MPLS TE tunnel interface
view.
3. Enable route pinning.
4. Submit
configuration.

Configuring administrative group and affinity attribute

The affinity attribute of an MPLS TE tunnel identifies the properties of the links that the tunnel can use.
Together with the link administrative group, it decides which links the MPLS TE tunnel can use. This is
done by ANDing the 32-bit affinity attribute with the 32-bit link administrative group attribute. When
doing that, a 32-bit mask is used. The affinity bits corresponding to the 1s in the mask are "do care" bits
which must be considered while those corresponding to the 0s in the mask are "don't care" bits.
For a link to be used by a TE tunnel, at least one considered affinity bit and its corresponding
administrative group bit must be set to 1.
