Refer to the exhibit. In a redundant hub-and-spoke deployment using EIGRP, what feature can be used to ensure that routers C through F are not used as transit routers for data traveling from router B to network 10.1.1.0?
Select the best response.
A.
Use address summarization at routers C, D, E, and F.
B.
Use the EIGRP Stub feature on routers C, D, E, and F.
C.
Use passive-interface on the spoke links in routers A and B.
D.
Change the administrative distance in routers A and B for routes learned from routers C, D, E, and F.
Answer: B
Explanation
By configuring “stub” feature on routers C D E and F, routers A and B will not try to transit traffic through these routers. For example, if the network connecting from routers A and B is down, router B will not send to network 10.1.1.0/24 from router B -> routerC/D/E/F -> router A -> network 10.1.1.0/24.
