GMPLS (Generalized Multiprotocol Label Switching Architecture) is a new Frame-work of protocols which is not only an extended version of MPLS. Instead of that It is a specialized group of protocols to discover neighbors, discover link state infor-mation, topology management, route management, load balancing, centralized control, bandwidth on demand management and man-agement of VPNs (Virtual private networks) in physical-optical level through the use of adequate optical de-vices. In this paper are evaluated the results of a simulation for autodiscovery mechanism for a layer one VPN using the OSPF-TE and BGP protocols and com-paring them. This paper pre-tends to give a vision to the reader of the potential of GMPLS framework and analyze the advantages and disadvantages to use OSPF-TE instead BGP for autodiscovery purposes in a layer one virtual private network for an specific network scenario.
