Refer to the exhibit. An architect is designing a hierarchical ISIS solution for a customer with these requirements: - Routers will double in all areas within the next 24 months. - Link flaps within areas 20 and 30 must not impact the backbone area. - Traffic originating from A201 and A302 routers must connect to application servers in the backbone. Which design must the architect select?
Correct Answer: A
An L2 router is similar to an OSPF backbone router. A router that has both Level 1 and 2 routes is similar to an OSPF area border router (ABR). IS-IS does not define a backbone area like OSPF's area 0, but you can consider the IS-IS backbone a continuous path of adjacencies among Level 2 ISs.
