Scenario

A simple example scenario designed to show and experiment with the Olive based Juniper router emulation capabilities of VNX. The scenario is made of 6 virtual machines: three Olive routers (r1, r2, r3) interconected in a triangle topology; and three Linux (Ubuntu) hosts (h1, h2, h3), each connected to a LAN serviced by one of the routers (see figure below). The host has an interface on the scenario connected to one of the LANs.

Olive example scenario

To start the scenario just type:

cd /usr/share/vnx/examples/
vnx -f example_olive.xml -v --create

After that you will see the consoles of the 6 virtual machines created. To access the Ubuntu hosts just use the standard login/password (root/xxxx). To access the Olive routers use whatever you have configured (remember that we cannot distribute root-file-systems for Olive; you have to create it yourself and be aware of the legal restrictions).

At startup, the Olive routers load a configuration that is made of the configuration specified in the <conf> tag:


You can show the map of the scenario with:

vnx -f example_olive.xml -v --show-map
