Configuration Roadmap

Configuration Roadmap

Use OSPF as an IGP to ensure that network-wide devices can be reached through routes and set up MPLS LDP and MPLS TE over OSPF routes. The configuration roadmap is as follows:

1. Add all devices to area 0 and advertise the directly connected network segment and the address of loopback interface 1.
2. Configure all interfaces that do not run OSPF as OSPF silent interfaces to disable the interfaces from sending or receiving OSPF packets. The configuration makes the OSPF network more adaptive and saves network resources.
3. Considering the impact of 31-bit subnet masks, configure the OSPF network type to point-to-point on the main interoperation interface.
4. Configure synchronization between OSPF and LDP to prevent traffic loss caused by switchovers of the primary and backup LSPs.
