Use the ping command to confirm the destination can’t be reached. A traceroute would also reveal the closest router (or hop) that fails to respond as expected. In this case, the router would then send an Internet Control Message Protocol (ICMP) destination unreachable message back to the source. The next step is to investigate the routing table using the show ip route command. Look for missing or misconfigured routes. Incorrect static routes are a common cause of routing problems. 2.4 Chapter Summary Summary Explain the advantages and disadvantages of static routing. Explain the purpose of different types of static routes. Configure IPv4 and IPv6 static routes by specifying a next-hop address. Configure IPv4 and IPv6 default routes.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
