Abstract
The effect of Network link failure is undesirable
which necessitated redundant links for reliability. This implies
that operations are switched between links in case of failure. In
the modern world where speed matters, it is important to
investigate how quickly different routing protocols, in this case,
Open Shortest Path First, OSPF and Routing Information
Protocol, RIP recovers in case of link failure in a mesh topology.
The research was simulated using OPNET. It was modelled after
the University of Salford main campus, using three of its
building, Newton, Peel and CW library. There were several links
in between the buildings. There network was configured for the
two routing protocols in different scenarios to test for their
performance in case of single and multiple link(s) failure and
recovery. It was observed that RIP converges faster (11.21s)
than OSPF (53.06s) at the initial stage of the network in all
cases. However, OSPF converges faster (Average of 5s – link
failure, Average of 15s – Link recovery) than RIP (Average of
18.57s- link failure, Average of 18.28s – link recovery) in both
single and multiple link(s) failure/recovery scenarios.Therefore,
based on the performance comparison, OSPF should be used in
a network prone to frequent link failure as it performs better in
this situation. However, RIP would be preferred
