Question 4

A router in AS 65100 receives two BGP routes. The first route is for 138.1.1.0/24 with an AS Path of 65200
65300, Local Preference of 100, MED of 100, and router ID 10.10.10.10. The second route is for 138.1.0.0/16 with an AS Path of 65500 65300, Local Preference of 150, MED of 100, and router ID 10.1.1.1. Assuming all other attributes are equal, which route would be used to forward an IP packet with destination IP address
138.1.1.1?
