An OSPF neighbor adjacency is not formed between R3 in the main office and R6 in the Branch3 office. What is causing the problem?
| A. |
There is an area ID mismatch. | |
| B. |
There is a PPP authentication issue; the username is not configured on R3 and R6. | |
| C. |
There is an OSPF hello and dead interval mismatch. | |
| D. |
The R3 router ID is configured on R6. |
Using the show running-config command we see that R6 has been incorrectly configured with the same router ID as R3 under the router OSPF process.
