pls help in a routing question

RTA# show ip route ospf

O IA [110/65] via, 00:00:28, Serial2/1/0

O* E2 [110/1] via, 00:00:16, Serial2/1/0

Refer to the exhibit. On the basis of the information presented, which statement is true?

A - A default route is configured on the local router.

B - Network was learned from an OSPF neighbor within the area.

C - OSPF router is an ABR.

D - The default route is learned from an OSPF neighbor.

Answer: B


I didn't got the idea of the answer, so anyone can help?


Re: pls help in a routing question


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

HTH, please do rate all helpful replies,

Re: pls help in a routing question

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 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.

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.
