One of the OSPF on FR: NBMA mode

Experiment topological diagram

Experimental purposes

Debug OSPF configuration in Frame Relay environment, NBMA network mode

Experimental configuration

(i) Configure IP addresses

(ii) running OSPF and informing the network

(iii) View R1 's neighbors and interface status

Through the view, found that three routers did not establish a neighbor relationship

Each router treats itself as a multiple access link to the DR
