I observed that packets from AS2 to 8.8.8.8 failed after reaching 10.0.2.1 (AS1). I verified the routing table, firewall rules, interface states, and neighbor table on AS2, all of which appeared correct. A ping test to AS1 was successful, confirming basic connectivity. I decided to provide detailed information to AS1, including the routing table and traceroute results, to facilitate further investigation. This was done because the issue seemed to lie with AS1 or the path beyond it, and coordination with AS1 was necessary to resolve the problem.
