This paper describes the different IP fast rerouting schemes using backup topology. This paper describes the scheme which comes under complete IPFRR frame work as according to IETF (Internet Engineering Task Force).The first section gives the basic idea about the IPFRR used for the rerouting purpose. The second section deals about the different methods used under IPFRR with concepts and examples. The third section describes the basic three configuration scenario for IPFRR. The fourth section gives the conclusion on the basis of the comparative theoretical studies made in the above sections and tries to find the best for rerouting.
