Exam 200-301 topic 1 question 357 discussion

Ospf processes can differ on each router and neighborship will form Ospf area must be the same to form adjacency Hello and dead timers must match to form adjacency Ospf Default hello timer is 10 and dead timer is 40 In This case R1 hello timer was modified to 5 seconds Timers was not changed on R2 hence using the default timers So C is correct

The given answer is correct, the default hello time is 10 seconds which causes a mismatch

C is correct

Keith Barker's acronym for OSPF neighborship: TAN - MAT These must match in OSPF. Timers Area number Network address MTU size Authentication Type (Network type: broadcast (with ethernet) or p2p)

C is correct

C is correct Hello and dead timer should much

Router ID can not be an issue. At least if the Areas were different but are all using area "0". The given answer "C" is correct, default hello time is 10 seconds and died time its times four of hello timer. In this case, the routers are using differ hello timer which results in fail of OSPF relationship

Process ID MUST BE Different. So the answer is correct

process IDs are not matching. A is the correct answer.

Router-Id and process OSPF son de importancia local; el valor default de los hello es de 10, por lo cual la respuesta es correcta. C.

Hey y`all how about the process ID? I think that should also be the answer
