Router R1 directly connects to subnet 10.1.1.0/24 with its Fa0/0 interface. R1 can ping four
other working OSPF routers in that subnet. R1 is neither the designated router (DR) nor
backup DR (BDR). OSPF is working correctly on all five routers. Which of the following is
true on R1? (Choose two.)
A.
The show ip ospf neighbors command lists two neighbors off Fa0/0.
B.
The show ip ospf neighbors command lists four neighbors off Fa0/0.
C.
The show ip ospf neighbors command lists two neighbors off Fa0/0 in the FULL state.
D.
The show ip ospf neighbors command lists two neighbors off Fa0/0 in the DISCO state.
Explanation:
On a LAN, the non-DR routers form fully adjacent neighborships with only
the DR and BDR, giving R1 two neighbors in the FULL state. The other two neighbors
settle into the 2WAY state.
