EIGRP OTP (Over The Top)

Hello Aysar

Since the command is unavailable on that particular IOS version, I would assume that the feature is unsupported. Indeed, looking at this Cisco command reference for the command, the command was introduced in Cisco’s IOS XE release 3.10S, and it was actually incorporated into IOS release 15.3(3)S, which is actually a later version than the one you are using. So it would seem that your particular version does not support it.

Take a look at Cisco’s Feature Navigator for a more concise picture of available features on particular IOS versions and platforms.

I hope this has been helpful!
