Abstract Abstract
Routing with link state protocols in dense network topologies can Routing with link state protocols in dense network topologies can
result in sub-optimal convergence times due to the overhead result in sub-optimal convergence times due to the overhead
associated with flooding. This can be addressed by decreasing the associated with flooding. This can be addressed by decreasing the
flooding topology so that it is less dense. flooding topology so that it is less dense.
