Refer to the exhibit.
A customer currently has a large EIGRP based network with several remote sites attached. All remote sites connect to the two Corporate data centers, depicted as 10.1.1.0 and 10.1.2.O. The customer has experienced several network wide failures where neighbours were stuck in active and had other network stabilitty issues due to some links flapping.
Which two redesign options increase network stability and reduce the load on the remote site routers, while still maintaining optimal routing between remote sites and the two data centers? (Choose two)
A . Perform summarization at the remote sites, selectively leaking route’s sent to the data centers
B . Set the hello interval timer to be larger than the hold interval
C . Set the data center routers as stub routers
D . Perform summarization at the data centers, selectively leaking routes sent to the remote sites
E . Increase the hold interval to accommodate lost hello packets on error prone links
