hi,

Answer B is correct as the "O IA" means Inter Area OSPF route --> route learned within the same area.

Hi Mahmoud,

AFAIK O IA are inter area routes which are originated from other areas and O are intra area routes which are generated from within area.

I believe answer B is correct because 6.0.0.0/8 is learned from neighbor which is within the area and I believe its learned via 5.x.x.x which may be its neighbor and may be in same area.

Ankur

Hi Ankur,

You are absolutely right "O IA" means Inter Area not Intra Area, i truly apologies for this newbie mistake :), and i think that your explaination is definitely right.

HTH,

Hi Ankur,

thanks a lot for your answer.any way, it seems that B is the correct answer even though it not clear that 5.x.x.x is within the area.
