Configuration Roadmap
The configuration roadmap is as follows:
1. Configure static routes between LSRs to ensure network connectivity.
2. Enable MPLS and MPLS LDP in the system view and interface view.
3. Configure synchronization between LDP and static routes and verify the configuration.
Data Preparation
To complete the configuration, you need the following data:
l IP addresses of all interfaces
l MPLS LSR IDs of LSRs
l Value of the Hold-down timer
Procedure
Step 1 Configure an IP address for each interface.
# Configure IP addresses for interfaces according to Figure 2-15. The configuration details are
not provided here.
