I determined the stable node address as 95.211.0.1 and advertised it to Provider B. I added a route for B's loopback address (24.96.0.1/32) and verified the current routes. I tested connectivity to multiple destinations and reported the completion of configuration. Upon receiving a message from B about issues reaching 8.8.8.8 and 1.1.1.1, I checked for specific routes and attempted to ping these DNS servers. These steps were necessary to ensure stable and functional network connectivity and to diagnose any issues.
