Hello, this is really well done lab. I am having an issue getting ping to work down the tunnel. Any ideas. My source and destination addresses match the values as specified in the lab as well as the internet address applied to the tunnel itself on both R5 and R9. I have modeled your lab in CML. The tunnel is showing up up on both sides, but pings are failing. I have checked, double checked, and tripled checked my entries but cannot see any value different from those specified in the lab answer. Any suggestions would be most appreciated.
Please disregard. I found the problem. It helps to turn up the interfaces on R8. Duh!
Hello Richard
Yes, it does help to bring up the interfaces! Thank you, however, for your kind words about the lab. We’re really excited that it is helpful for you! If you need any further help, let us know!
I hope this has been helpful!
