Routing Protocol Simulators

[Daniel O Awduche <awduche () zonker ecs umass edu>]

I am in need of routing protocol simulators, and would be
most appreciative if information can be provided on 
available packages (commercial and/or public domain).
In particular, packages that can provide realistic
simulation of the ISIS and/or OSPF protocols would be
most ideal.

Thank you for your time.

Daniel Awduche.
