The traceroute command will help identify a broken router between the local and the remote machine. The traceroute command sends a series of packets with increasing time-to-live (TTL) values to a destination and displays the routers that the packets pass through along the way. If a router is broken or unreachable, the traceroute command will show a * symbol or a timeout message. The traceroute command is part of the topic 109.1: Fundamentals of internet protocols, which is one of the objectives of the LPI Linux Administrator - 102 exam12. References: 1: https://learning.lpi.org/en/learning-materials/102-500/  2: https://www.lpi.org/our-certifications/exam-102-objectives/
