I'm preparing for my CCNA exam and just found two different answers from a question below, could you please tell me what is the correct one...
Q- A network with 15 hosts has one connection to the internet through the R1 route. What routing are recommended in the R1 and ISP router?
From two different books I got the answer
1. A default route on R1 and static route on the ISP router
2.A default route on both routers.
Please can you advise what is the correct one?
First is the correct answer becoz ISP may be connected to different locations other than R1 ...so Statis route must be configured on ISP router.
R1 dosen't know about the networks or destinations to reach within or beyond the ISP ...so a default route pointing towards serial ip of ISP is needed on R1 router.
deafult route---> <---static route
I accept to Mohammed Mahmoud answers. Answer "1" is the Correct.
Sorry, i mis-understood the question.
Default Route from R1 to pass all traffic to ISP Network
Static Route from ISP side to R1 for routing back the return Packets.
Pls Rate if Helps
