You are a junior network engineer for a financial company, and the main office network is experiencing network issues. Troubleshoot the network issues.
Router R1 connects the main office to the Internet, and routers R2 and R3 are internal routers.
NAT is enabled on router R1.
The routing protocol that is enabled between routers R1, R2 and R3 is RIPv2.
R1 sends the default route into RIPv2 for the internal routers to forward Internet traffic to R1.
You have console access on R1, R2 and R3 devices. Use only show commands to troubleshoot the issues.
Why applications that are installed on PCs in R2 LAN network 10.100.20.0/24 are unable to communicate with server1?
Click on the arrows to vote for the correct answerA. B. C. D.
We should check if we can ping from R1 to Server 1 or not:
The ping worked well so maybe R1 is good so we should check R2 first. We notice on R2 there is an access-list:
This access-list is applied to E0/2 interface with inbound direction. The purpose of this access-list is to block traffic with source IP address of 172.16.200.0/24 so it will block all traffic sent from Server 1 to us.
