Multi-protocol Label switching is the evolving technique which is used in providing high speed networking and traffic engineering efficiently in the networks. This paper is very potent than the IP routing as it uses the Label switching technique. Label assignment is critical for the accurate delivery of data sent by the user. However the protocols for label distribution are not secure. Thus, if an intruder compromises a node by intercepting and modifying, or more simply injecting false labels into the LIB (Label Information Base) were the labels are stored, the propagation of improperly labelled data flows could create instability in the entire network.
