Which two design recommendations are most appropriate when EIGRP is the data center core
routing protocol? (Choose two.)
A.
Summarize data center subnets.
B.
Advertise a default route into the data center core from the aggregation layer.
C.
Tune the EIGRP timers to enable EIGRP to achieve quicker convergence.
D.
Adjust the default bandwidth value to ensure proper bandwidth on all links.

Here are some recommendations on EIGRP design for the data center core layer:
■ Advertise a default summary route into the data center access layer with the ip
summary-address eigrp interface command on the aggregation layer.
■ If other default routes exist in the network, such as from the Internet edge, you
might need to filter them using distribute lists.
■ Summarize the data center access layer subnets with the ip summary-address eigrp
interface command from the aggregation layer.
■ Use the passive-interface default command, and advertise only on the links that need
to participate in the routing process using the no passive-interface interface command
