I’m in final preparation for my second attempt and I have been doing a lot of troubleshooting scenarios lately. I created a MPLS topology in GNS3 and sent it to my friend Darren for testing. He is taking his lab very soon and he performed well on this lab. The lab contains multiple faults but I won’t say how many since that would spoil some of the surprise.
The assignment is to make sure CE1 can ping CE2 loopback 188.8.131.52.
Post in comments what you did to make it work or if you need a hint to get you going in the right direction. You need to edit the .net file to use your own working dir and IOS image. You need IOS images for 3725 and 7200. Start with the configurations provided by importing the configs or simply pasting them in whatever you prefer but you should not look at the startup config before starting.
Download the .net and config files here.
This is what the topology looks like.
