Abstract:
In today's real-world scenario, using multiple dynamic routing protocols for forwarding packets
has become a normal job for the network administrators. Therefore, the route redistribution is an
important issue in an enterprise network that has been configured by multiple different routing
protocols in its routers. In this study, we analyze the performance of the combination of three
routing protocols in each scenario and make a comparison among our scenarios. We have used
the OPNET 17.5 simulator to create the two scenarios in this paper by selecting three different
routing protocols from the distance vector and link state routing protocols in each scenario. In the
first scenario, we have configured the network routers with EIGRP, IGRP, and OSPF that is
named EIGRP_IGRP_OSPF in our simulation. Here EIGRP is used on the server side and OSPF
is used on the client side. The OSPF_IGRP_ISIS scenario is a mixed from EIGRP, IGRP, and
IS-IS protocols that is the second scenario and OSPF is used on the server side and ISIS is used
on the client side. The third scenario is OSPF_IGRP_EIGRP that is the route redistribution
among OSPF, IGRP, and IS-IS protocols and OSPF is used on the server side and EIGRP is used
on the client side. The simulation results showed that the performance of the EIGRP_IGRP_ISIS
scenario is better than the other scenarios in terms of network convergence time, throughput,
video packet delay variation, and FTP download response time. In contrast, the
OSPF_IGRP_ISIS has less voice packet delay variation, video conferencing and voice packet
end-to-end delays, and queuing delay as compared with the two other scenarios. On the other
hand, the performance of the OSPF_IGRP_EIGRP scenario has the better FTP upload response
time, and voice jitter.
