UTI is generally less popular than GRE, as GRE is standards based and UTI is prestandards based. In a new deployment, GRE would be the way to go due to QoS features alone.

Thanks for yr valuable input. Please suggest what interface on ingress/egress & backbone side required for 7500 to enable UTI, I find Cisco document ref avout engine 0, engine 1 , engine 2, I am not sure whether 7500 does has these engines(7200 & 12000 I am aware), please share yr input on the same.

I also observe that UTI would be helpful to carry Frame-Relay over IP in a transparent manner(maintaining end DLCI un-altered) where as GRE does not, so I see this as one of the advantage, correct me if I am wrong.
