| |
| − | | |
| − | [http://www.nsf.gov/ NFS] (National Science Foundation) is the US Research and Education Network (NREN). Although there are several incarnations of the NFS net, here we consider the one described in the [http://www.ikr.uni-stuttgart.de/Content/Publications/Archive/Ko_ITGPhotNetze04_36322.pdf |following document] (also shown in the figure below) is composed of 14 network nodes connected through 21 point-to-point links (each one a /30 network).

| − | A VNUML scenario implementing the NSF topology is shown in this example. However, note that given that the scenario does not include routing configuration (by the moment), neither static nor dynamic, only directly connected nodes are reachable each other. However, it could be possible to run some dynamic routing process (eg., OSFP) in the nodes in order to get global connectivity.

| − | '''Thing to do'''. If you want to help us to improve this example (please, [mailto:vnuml-at-dit.upm.es tell us about] :), the following enhancements could be done:
| |
| − | | |
| − | * A IPv6 version of the scenario (using the [[Reference#<ipv6>|<ipv6>]] tags)
| |
| − | * To implement OSPF-based routing to get global connectivity (consider, for example, to adapt the [[Example-OSPF|OSFP example]] to the NSF scenario)
