Multiprotocol Label Switching (MPLS) is an emerging technology which ensures the reliable delivery of the Internet services with high transmission speed and lower delays. The key feature of MPLS is the Layer 3 VPN service that can provide a secure connection to any enterprise between its sites around the world. GNS3 has been used to build a network topology of internet service provider (ISP) MPLS core network. Moreover, OPNET 17.5 modeler which is network simulation tool software has been used to compare the performance of three different routing protocols; Routing Information Protocol (RIP), Open Shortest Path First (OSPF) and Enhanced Interior Gateway Protocol (EIGRP) in order to show the most suitable routing protocol needed in the small ISP MPLS core network. The results shows that the RIP has the highest time average end to-end delay which is 0.19μs and the OSPF has the highest network convergence time which is 18.5 Seconds during the first minute of the all simulation period.
