NAME

       vde_l3 - Virtual Distributed Ethernet 'Layer 3' Switch.

SYNOPSIS

       vde_l3  -v  vde_plug:ipaddress/netmask  [-v...]   [-r  target_network/netmask:gateway] [-G
       default_gw] [-M mgmt_socket]

DESCRIPTION

       A vde_l3 connects to one or more vde_switches, performing ip forwarding among its  virtual
       interfaces.  A  new  interface  is  created at startup for each -v option given at command
       line. Static routes to target networks can be defined using the -r option.

       vde_l3 -v /var/run/s1.ctl:192.168.0.1/24

       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.

       vde_l3 \

       -v /var/run/s1.ctl:192.168.0.1/24 \

       -v /var/run/s2.ctl:10.0.0.254/255.255.0.0

       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  vde_l3  as
       their gateway to reach the other one.

OPTIONS

       -v vde_plug:ipaddress/netmask
              Creates  a virtual network interfaces on the vde_l3 box, with address ipaddress and
              netmask netmask. 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.

       -r target_network/netmask:gateway
              Specify a static route through  gateway  to  reach  hosts  in  target_network  with
              netmask netmask.  One can define as many routes as she wants.

       -G default_gw
              Specify  a  default  gateway,  to be used whenever no static route is defined for a
              target host.

       -M mgmt_socket
              the unix socket where the parameters (interfaces addresses, routes,  etc.)  can  be
              checked  and  changed  runtime.  unixterm(1)  can  be used as a remote terminal for
              wirefilter.
