Scenario
This example shows the VNUML implementation of a networking laboratory for OSPF dymanic routing protocol tests. It is a virtual implementation of the real-based network laboratory testbed of the Telematic Networks and Services Laboratory (in Spanish) last exercise at DIT-UPM grade course. This environment was used at ITHET'04 in order to illustrate VNUML application for high educational purposes.The laboratory tries to resemble to the network of a distributed organization. The core of the network is a backbone (routers RB1, RB2, RB3 and RB4) that interconnects several regional headquarters (from A to F) to the central organization headquarters. Each regional headquarters provides connectivity for two sites (from 1 to 12).
The network layout is shown in the picture. Click here to see a high resolution copy of the map.
- Each site is composed of a computer (PCx) and an outbound router. The computer is configured with a default route to the outbound router.
- Each regional headquarters is composed of a server (SRx), an inbound router (RRx2) and an outbound router (RRx1). The server is configured with a default route to the outbound router.
- The central headquarters of several internals routers (RC1, RC2, RC3 and RC4) and a server (SC). All them are configured with default routes to the backbone. All the routers in the simulation (except for the ones in the central headquarters) 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. You'll need to download the [ospf_lab_conf.tar.gz configuration for ospfd daemons] and unpacked it in the examples directory:
cd /usr/share/vnuml/examples tar xfvz ospf_lab_conf.tar.gz
Note that this is a very big VNUML simulation, involving 51 virtual machines and 45 virtual networks. So, be aware that the hosting machine could get stressed (or even worse!). You can use the -w switch to increase the boot timeout (see User Manual for details). For example:
vnumlparser.pl -t ospf_lab.xml -v -w 120
(However, if your simulation is too big for your host, try to use a tiner version of the VNUML specification. For example, try to remove some of the regional headquarters and/or sites. There is a [ospf_lab_tiny.xml tiny version of ospf_lab.xml] with regional headquarters C, D and E; sites 2, 3 and 11; and servers SRA, RFB and SRF commented out in the XML)

You can download the simulation file from [ospf_lab.xml here].
The example could be improved in several ways. For example:
- The simulation is too big and this has a significative impact when building topology. A solution could be to split the simulation in several pieces, and building only desired parts for each testing case. Read more about this in the [../../user/index.html#concurrent_simulations VNUML User Manual].
- The provided configuration for ospfd daemons is quite simple: all the routers uses OSPF in all their directly connected networks and a single area is use. A multiarea configuration could be more desirable. In addition, some networks (specially PPP-like links between some routers) shouldn't be globally advertised.
