Question #: 144
Topic #: 1

Refer to the exhibit. A network engineer installed a new router (Router 3) at the regional hub running MPLS services for scalability. Router 3 is connected to the 10.44.4.0/24, 10.44.5.0/24, 10.44.6.0/24, and 10.44.7.0/24 subnets. The new router has been configured for OSPF Area 2, and it is advertising the four connected networks. The engineer noticed that the same networks are listed as interarea summary routes, and they are being flooded into each area on the area borders. Which action resolves the issue?

A. Under the OSPF configuration on Router 2, add area 2 range 10.44.4.0 255.255.252.0.
B. On Router 3, configure an access list to filter the networks.
C. Under the OSPF configuration on Router 3, add area 2 range 10.44.4.0 255.255.252.0.

Unclear what is the request here. Judging by the answers, probably summarization is expected (which is unrelated to 'interarea summary routes'), and in this case A is correct. Filtering doesn't seem to make sense here anyway.
