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.
