A. B. C. D.A.
When configuring EIGRP on Data Center switches, there are several design considerations to take into account. Let's go through each answer option to see which one is correct:
A. Perform manual summarization on all Layer 3 interfaces to minimize the size of the routing table.
This option suggests that manual summarization should be performed on all Layer 3 interfaces to reduce the size of the routing table. While summarization can help reduce the size of the routing table, it should not be done on all interfaces. Summarization should be done only where it is necessary and appropriate. Over-summarization can result in suboptimal routing and can cause issues with reachability.
B. Prevent unnecessary EIGRP neighborships from forming across switch virtual interfaces.
This option suggests that unnecessary EIGRP neighborships should be prevented from forming across switch virtual interfaces. This is a valid design consideration, as forming EIGRP neighborships across switch virtual interfaces can result in excessive routing updates and increased network overhead. To prevent this from happening, you can use the passive-interface command on the switch virtual interface.
C. Lower EIGRP hello and hold timers to their minimum settings to ensure rapid route reconvergence.
This option suggests that the EIGRP hello and hold timers should be lowered to their minimum settings to ensure rapid route reconvergence. While lowering the hello and hold timers can result in faster route reconvergence, it can also increase the amount of EIGRP traffic on the network. This can result in increased network overhead and potential scalability issues. It is important to carefully consider the impact of changing the EIGRP hello and hold timers before making any modifications.
D. Configure multiple EIGRP autonomous systems to segment Data Center services and applications.
This option suggests that multiple EIGRP autonomous systems should be configured to segment Data Center services and applications. While this is a valid design consideration, it may not be necessary in all cases. Segmenting services and applications using multiple EIGRP autonomous systems can increase the complexity of the network and may require additional configuration and management overhead. It is important to carefully consider the benefits and drawbacks of this approach before implementing it.
In conclusion, the correct answer is B: prevent unnecessary EIGRP neighborships from forming across switch virtual interfaces. This is a valid design consideration when configuring EIGRP on Data Center switches, as it can help reduce network overhead and improve scalability.
