<H2>DESCRIPTION</H2>

A
<B>vde_l3</B> 
connects to one or more vde_switches, performing ip forwarding among its virtual
interfaces. A new interface is created at startup for each <B>-v</B> option given at
command line. Static routes to target networks can be defined using the <B>-r</B> option.
<P>
<B>vde_l3 -v /var/run/s1.ctl:192.168.0.1/24</B>

<P>
connects to the vde sock at /var/run/s1.ctl with its virtual interface ve0, having
the address 192.168.0.1 and netmask 255.255.255.0.

<P>
<B>-v /var/run/s2.ctl:10.0.0.254/255.255.0.0 </B>

<P>
connects to the two vde socks, with its virtual interfaces ve0 and ve1, having addressess 192.168.1.0 and 10.0.0.254 respectively. Hosts in each network can specify the 
<B>vde_l3</B> as their gateway to reach the other one.

<H2>OPTIONS</H2>

<DL COMPACT>
<DT><B>-v</B><I> vde_plug:ipaddress/netmask</I>

<DD>
Creates a virtual network interfaces on the <B>vde_l3</B> box, with address <I>ipaddress</I> and netmask <I>netmask</I>. Please note that the netmask can be specified either in 
the 'classic' A.B.C.D mode, or just by giving the number of leading bits (f.e., /17 for 255.255.128.0).
One can define as many interfaces as she wants.
<P>
<DT><B>-r </B><I>target_network/netmask:gateway</I>

<DD>
Specify a static route through <I>gateway</I> to reach hosts in <I>target_network</I> with netmask <I>netmask</I>.
One can define as many routes as she wants.
<P>
<DT><B>-G </B><I>default_gw</I>

<DD>
Specify a default gateway, to be used whenever no static route 
is defined for a target host.
<P>
<DT><B>-M </B><I>mgmt_socket</I>

<DD>
the unix socket where the parameters (interfaces addresses, routes, etc.) can be checked and
changed runtime. <B><A HREF="/#/man/man1/unixterm.1.html">unixterm</A></B>(1) can be used as a remote terminal for wirefilter.
