COST value 1. Topology: 2. Configuration and Description: 1. Configure the IP address and ospf protocol of each interface. I used an R0 router to configure a frame relay switch. This helps us better understand frame relay. Note: When R1 and R4 use the FR interface, you can define the interface type ip ospf network broadcast or manually specify the neighbors of the two interfaces. Otherwise, the neighbors may fail. 2. Then we can manually specify the
