In the network presented in the following exhibit, all routers are configured to perform EIGRP on all interfaces. All interface bandwidths are set to 1000, and the delays are configured as displayed. In the topology table at Router P4S-RC, you see only one path towards 10.1.1.0/24. Why Router P4S-RC only has one path in its topology table?

Router P4S-RB is not advertising 10.1.1.0/24 to Router P4S-RC due to split horizon.
Router P4S-RD is not advertising 10.1.1.0/24 to Router P4S-RC because Router P4S-RC is its feasible successor.
