I could give that a try and I will if I do net get a resolution but I have 15 - 20 of these tunnels and i would like to keep them standard.

Hi Mike,

Two suggestions:

1.) Try to create a completely new Tunnel interface (Tunnel100 for example) and use the tunnel mode eon as the very first command on that interface. Only then try to add the remaining commands.

2.) I noticed that the IOS running on your 3825 is IP Base. Honestly, I am not sure if the EON encapsulation is available in the IP Base feature set. I have been using Advanced IP Services for my experiment.

Best regards,

Peter

I tried 1 early on to no effect but I had noticed that it was running IPBASE as well and have just upgraded to ENTBASE and it now accepts the command, Thanks for your help

Mike

Mike,

You are welcome. And thanks for asking - this has been my first "exposure" to the EON type of tunnels. Thanks to you I've learned something new.

Best regards,

Peter
