LAYER 3 MULTI-PROTOCOL LABEL SWITCHING BASED ON VIRTUAL PRIVATE NETWORK
ABSTRACTThis research was devoted to the design of a Layer 3 Multi-protocol Label Switching based on Virtual Private Networks, which is one of the major key technology of Service Providers' Services for corporations who desire to use remote connectivity.
In spite of the complexity of the underlying architecture of Layer 3 Multi-Protocol Label Switching, it was easy to configure and maintain a Virtual Private Network with Layer 3 Multi-Protocol Label Switching as it is flexible and omnipresent in internet service provider`s network
To attain the objectives of this research, we used GNS3, a Graphical Network Simulation tool used by network structural engineering for simulating a real world scenario. A number of steps for configuring various routers and firewall were followed in order to come up with a simple Virtual Private Network structure consisting of two Provider Edge routers, two Provider routers, and four Customer Edge routers.
All configurations were accurate configure, including complete routing tables and end-to-end connectivity verification using the Ping command. The designed implementation is through the Internet Service Provider (ISP).
Therefore, the research would lead to lower costs of the network infrastructure while benefiting from the advantages of fiber optic connectivity among others.
