Hi Sandeep,
In IOS versions where WCCP is VRF aware, such as 15.0M and 15.1T, the use of GRE redirection will result in some new tunnel interfaces appearing. On the ASR platform these tunnel interfaces are also present from IOS XE release 2.5 onwards (although VRF support within WCCP on the ASR platform is not present until IOS XE release 3.1).
So what you see is perfectly normal and you cannot do anything to change this, unless you want to change the WCCP redirection mode, or disable WCCP completely.
