hi guys,
I have a question regarding static routes and CEF, and I would be thankful I you help me with it.
How will a router handle static routing differently if Cisco Express Forwarding is disabled?
- It will not perform recursive lookups.
- Ethernet multiaccess interfaces will require fully specified static routes to avoid routing inconsistencies.
- Static routes that use an exit interface will be unnecessary.
- Serial point-to-point interfaces will require fully specified static routes to avoid routing inconsistencies.
Thanks
One moment to express my appreciation for this site/community.
I guess the correct answer is the second option. but I am struggling to understand this answer.
Yes, as you said the second option is the right answer. However, In most platforms running IOS 12.0 or later, Cisco Express Forwarding is enabled by default. Cisco Express Forwarding eliminates the need for the recursive lookup. If Cisco Express Forwarding is disabled, multiaccess network interfaces require fully specified static routes in order to avoid inconsistencies in their routing tables. Point-to-point interfaces do not have this problem, because multiple endpoints are not present. Thus, with or without Cisco Express Forwarding enabled, using an exit interface when configuring a static route is a viable option.
I hope it helps!
Hey Eleanor,
Try to understand the questions and answers instead of cramming. In addition, 200-301 practice tests are quite good, and I highly recommend them.
Besides, your answer is right, and thanks to Gianna who provide us with an explanation of it.
Hi Rowan,
First, wish you the best of luck in your exam. I just passed my exam in June 2022, these questions are very helpful and there are some of them in the exam however try to expose yourself to as much questions as possible because majority of the questions were new.
Thank you, Guys, for your help, feedback, and kind pieces of advice.
I appreciate your support as well as your time!
