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.

You have console access on R1, R2 and R3 devices. Use only show commands to troubleshoot the issues.
