Click the Exhibit.
The router with the configuration shown in the exhibit has two interfaces, both of which are operational and can pass traffic. These interfaces are connected to two different routers, both of which are configured for OSPF area 0.0.0.1. The router has received LSAs and can now send traffic into the backbone area.
Which two statements are correct? (Choose two.)
The router is an ASBR (Autonomous System Boundary Router) because it is importing external routes into OSPF, as indicated by the policy statement that accepts routes from protocol direct and rejects specific static routes. This fits the definition of an ASBR. The router has only a single OSPF adjacency because one of the interfaces is configured as passive, which means it cannot form an adjacency, leaving just one interface to form an OSPF adjacency.
The correct ones are A and B. "A" becuase the router is importing external routes into OSPF, that is the definiton of ASBR. B Because, as it is possible to see in the config of ospf, it have just one area configured
why C? I think AB
The correct ones are A and B. "A" because the router is importing external routes into OSPF, that is the definiton of ASBR. "B" Because it has 2 interfaces configured for OSPF and 1 of them is in passive mode
Its neither ABR nor ASBR. Both routers connect to same OSPF area as per question. Area border router (ABR): An OSPF router with links in two areas, the ABR is responsible for connecting OSPF areas to the backbone. It transmits network information between the backbone and other areas Area border router (ABR): An OSPF router with links in two areas, the ABR is responsible for connecting OSPF areas to the backbone. It transmits network information between the backbone and other areas
Options B & C are correct. - The router is an ABR router because it links two OSPF areas and connect area 0.0.0.1 to the backbone. Already it's mentioned that the 2 interfaces are in area 0.0.0.1. - The interface configured as a passive interface makes it not qualified to participate in OSPF adjacency formation, hence, just a single adjacency is formed.
C because we can see that the question said that they are configured for OPSF Area 0.0.0.1. so it means that they are connected to the backbone with a configuration of Area 0.0.0.1. that's why they can be called as ABR. they can also send traffic to the backbone.
A and B are correct answer
ABR because we are importing static routes. one neighbor because of the key word passive.
One most important thing to note about an ABR is that, it must have at least one link in the Area 0. In the question, the router has not link in area 0 and so answers are A and B.
