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.
Configuration Prerequisites
The configuration tasks described in this section are about CSPF of MPLS TE. They must be used in
conjunction with CSPF and the dynamic signal protocol (CR-LDP or RSVP-TE). Before performing
them, be aware of each configuration objective and its impact on your system.
Configuration Procedure
Tuning CR-LSP setup involves these tasks:
z
Configuring route pinning
z
Configuring administrative group and affinity attribute
z
Configuring CR-LSP reoptimization
Configuring route pinning
Route pinning cannot be used together with reoptimization or automatic bandwidth adjustment.
Follow these steps to configure route pinning:
