Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 240

Network operations report issues with receiving too many external routes, which caused CPU spike on routers with smaller memories. Which action resolves the issue?

Answer options

• A. Configure the area range command when redistributing on ASBR.
• B. Configure the summary-address command when redistributing on ABR.
• C. Configure the area range command when redistributing on ABR.
• D. Configure the summary-address command when redistributing on ASBR.

Correct answer: D

Explanation

The correct action is to configure the summary-address command when redistributing on ASBR, as it helps to reduce the number of external routes advertised, thus alleviating CPU strain. The other options either pertain to area range configurations, which do not address the issue of external route overload effectively, or apply to the wrong router type (ABR) for this specific scenario.
