This work presents an implementation carried out in Network Simulator that allows the user to simulate and to analyze in a MPLS network the dynamic rerouting of CR-LSPs, in conformity with RFC3214. The addition of the parameter “Actionflag” to the header of the message and the creation and alteration of functions allow the dynamic rerouting of LSPs, using the same identifier, and consequently, a better administration of the resources of the network.
