Scenario
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 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).
Figure 1: NSFNet topology (with 14 nodes)
A VNUML scenario implementing the NSF topology is shown in this example. All the routers in the simulation run ospfd, a daemon process from the Zebra Suite that implements OSPF protocol. This protocol allows each router to configure dynamic routes so, after a convergence time, global connectivity is achive once the simulation has been started. Since version 1.9 of VNUML, OSPF-based routing have been implemented using OSPFD plugin with this configuration file.
Once the scenario is up, start the routing daemons (which configuration files are automatically generated by the OSPF plugin) using the following command:
vnumlparser.pl -x start@nsf-14.xml -v
Some examples of test performed with this virtual scenario:
- Connectivity from WA to GA:
root@WA:~# traceroute 10.0.50.13 traceroute to 10.0.50.13 (10.0.50.13), 30 hops max, 38 byte packets 1 10.0.5.6 (10.0.5.6) 0.371 ms 0.579 ms 0.262 ms 2 10.0.5.22 (10.0.5.22) 0.472 ms 0.420 ms 0.426 ms 3 10.0.50.13 (10.0.50.13) 0.594 ms 0.586 ms 0.507 ms
- Connectivity from WA to NJ:
traceroute to 10.0.50.11 (10.0.50.11), 30 hops max, 38 byte packets 1 10.0.5.10 (10.0.5.10) 2.862 ms 0.279 ms 0.226 ms 2 10.0.5.46 (10.0.5.46) 0.421 ms 2.355 ms 0.414 ms 3 10.0.50.11 (10.0.50.11) 0.561 ms 0.476 ms 1.424 ms
- OSPF information from ospfd at WA:
