Adjusting the Path of a CR-LSP
CSPF uses the TEDB and constraints to calculate appropriate paths and establishes CR-LSPs through the signaling protocol. MPLS TE provides many methods to affect CSPF computation to adjust the CR-LSP path.
Pre-configuration Tasks
Before adjusting the path of a CR-LSP, complete the following task:
- Configure a dynamic MPLS TE tunnel. For details, see Configuring a Dynamic MPLS TE Tunnel.
- Configuring Tie-Breaking of CSPF
- Configuring Metrics for Path Calculation
- Configuring CR-LSP Hop Limit
- Configuring Route Pinning
- Configuring Administrative Group and Affinity Property
- Configuring SRLG
- Associating CR-LSP Establishment with the Overload Setting
- Configuring Failed Link Timer
- Configuring Flooding Threshold
- Verifying the Configuration of Adjusting the Path of a CR-LSP
