In a redesign of a multiple-area network, it is recommended that summarization is to be implemented. For redundancy requirements, summarization is done at multiple locations for each summary. Some customers now complain of higher latency and performance issues for a server hosted in the summarized area. What design issues should be considered when creating the summarization?
A) Summarization adds CPU overhead on the routers sourcing the summarized advertisement.
B) Summarization prevents the visibility of the metric to the component subnets.
C) Summarization creates routing loops.
D) Summarization causes packet loss when RPF is enabled.
