I observed the initial configuration and performed a ping test to A, confirming the link was up. I then requested a traceroute from A to 88.99.0.1 due to packet loss. After receiving A's feedback about 100% packet loss when pinging my loopback address, I re-ran the ping test from my side, which was successful. I coordinated further with A, who provided traceroute results showing a clear path. Finally, I executed a ping test to 88.99.0.1, which succeeded, and reported the resolution to A, verifying the routing table. This approach ensured the issue was diagnosed and resolved, confirming full connectivity.
