You want to create an OSPF area that only contains intra-area route information in the form of Type 1 and Type 2 LSAs.
In this scenario, which area is needed to accomplish this task?
You want to create an OSPF area that only contains intra-area route information in the form of Type 1 and Type 2 LSAs.
In this scenario, which area is needed to accomplish this task?
To create an OSPF area that only contains intra-area route information in the form of Type 1 and Type 2 LSAs, you need a totally stubby area. A totally stubby area limits the types of LSAs allowed within it to only intra-area routes and a default route, effectively excluding Type 3, 4, and 5 LSAs, thus achieving the requirement stated in the question.
A totally stubby area (TSA) is a stub area in which summary link-state advertisement (type 3 LSAs) are not sent. A default summary LSA, with a prefix of 0.0. 0.0/0 is originated into the stub area by an ABR, so that devices in the area can forward all traffic for which a specific route is not known, via ABR.
