Hello,
You can have a configured and running network inside a single linux machine,
only one script command is enough. After the start of all the machine, a
graphical representation of your topology helps your interactions with
the network. This virtual network can be downloaded at http://clownix.net,
I must warn you, it is a 350mega bz2 file-system that needs 4 giga on
the host.
Very usefull for networking development in kernel as proved by bug 8895
that has been found with the above tool:
The uncorrected bug 8895:
file: /usr/src/linux-2.6.24.2/net/ipv6/ip6_fib.c line 796:

atomic_inc(&rt->rt6i_ref);

err = fib6_add_rt2node(fn, rt, info); <-**- return -EEXIST

(Here err was not null)

dst_free(&rt->u.dst); <--**-- Actually rt is still in
tree (fn->leaf = rt /* see above */)
