Abstract
MPLS-VPN technology is introduced to provide secure transmission with minimum propagation delay. This paper presents a comparative analysis of unicast routing protocols for MPLSVPN enabled networks. The motive behind this analysis is to observe the consequence of unicast routing protocols on the performance of MPLS-VPN enabled networks and to choose most suitable routing protocol for such type of networks. To conduct the analysis, a test bed is established in GNS3 simulator. Three main unicast routing protocols i.e. Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF) and Routing Information Protocol (RIP) has been considered in this work. Round-Trip-Time, Jitter and Administrative-distance are used as performance measure metrics. The experimental analysis indicates that EIGRP is the most suitable protocol among the aforementioned protocols for MPLS-VPN.
