Exam 200-301 topic 1 question 403 discussion

By the way, the interfaces on both routers have the same IP address

D is correct

Not in the options but both IP of the interfaces are the same. Plus hello and dead timer are different.

What about IP addresses on both e0 interfaces of the 2 routers? Is it correct both be the same?

Both have same IP, both are DR, shame on cisco

D is right because the hello and dead interval needs to match in order to maintain neighbor adjacency

First of all both the routers have same IP address. As well as both belong to same area 0 yet both of them are DR. How come its possible? There are more than 1 reason for these two routers to form ospf neighborship, let alone adjacency. But since there are some parameters which are need to matched in order to form ospf neighborship and timers mismatch is one of them. Thus, option D is correct.

The hello timer, dead and wait time differs on both routers, thereby causing the adjacency not to form

The hello timer interval differs on both router which is the reason why the adjacency did form a relationship.

Anyone notice that before we even talk about OSPF, the two routers have the same IP address. Definitely an error there.

I also don't see a BDR. The output even says no backup Designated Router on this network?

Agreed- same IP address. This was the first thing I noticed as well, but of course did not see it as an answer option so had to move on to another possibility
