The DR may be elected based on the lowest OSPF Router ID.
- D.
The DR may be elected based on the highest OSPF Router ID.
- E.
The DR attempts to become fully adjacent with every other neighbor on the subnet.

- 9.OSPF routers R1, R2, and R3 attach to the same VLAN. R2 has been configured with the ip ospf authentication message-digest interface subcommand on the LAN interface connected to the common VLAN. The show ip ospf neighbor command lists R1 and R3 as neighbors, in an Init and Full state, respectively. Which of the following are true?
- A.
R3 must have an ip ospf authentication message-digest interface subcommand configured.
- B.
R3 must have an ip ospf authentication message-digest-key interface subcommand configured.
- C.
R1's failure must be because of having configured an incorrect OSPF authentication type.
- D.
R1's failure may or may not be related to authentication.
