Some More Troubleshooting Fun With EIGRP
Recently I got this request from a friend working on CCNP. He was looking for some troubleshooting labs. So I thought to help him out with couple of labs and to other people who are preparing for CCNP TS exam.
So to add some fun I created this small troubleshooting lab last night. Below is the topology :
R1 should be able to reach R4's loopback and vice versa. For verification point of view the command - R4#ping 220.127.116.11 so lo0 should have 100% success rate. Also R4 should be able to telnet R1 and get login prompt.
Here are the initial configuration files and GNS topology for you guys :
Also recently I saw a nice post from CCIE Anthony at blog.ipexpert.com which might help you along the way:
Again... Being a good network engineer, Avoid using "sh run" and instead try to find and fix the problem using other "show" commands.
