# libvdeplug\_vxvde(1)

vdeplug module for vde\_switch based networks

## NAME

libvdeplug\_vxvde - vdeplug module for vde\_switch based networks

## SYNOPSIS

libvdeplug\_vxvde.so

## DESCRIPTION

This is the libvdeplug module to join vxvde networks. Vxvde is a distributed implementation of virtual networks. There is no need for extra processes like virtual switches.

This module of libvdeplug4 can be used in any program supporting vde like **vde\_plug**, **kvm**, **qemu**, **user-mode-linux** and **virtualbox**.

The vde\_plug\_url syntax of this module is the following:

**vxvde://**\[*multicast\_addr*\]\[**/***OPTION*\]\[**/***OPTION*\]

If *multicast\_addr* is omitted libvdeplug\_vxvde uses the default addresses: **239.0.0.1** for IPv4 and **ff05:56de::1** for IPv6.

## OPTIONS

- **v4**

  use IPv4

- **v6**

  use IPv6

- **port=***PORT*

  *define the multicast port (default value 14789)*

- **vni=***VNI*

  *define the virtual network identifier (default value 1).* *(a group name can be used as VNI, in that case the vni is the group id).*

- **ttl=***TTL*

  *define the time-to-live (default value 1).*

- **grp=***group\_name\_or\_number*

  *Set the VNI and the last three bytes of the IP address to the group id.*

- **hashsize=***HASHSIZE*

  *set the size of the hash table for packet switching*

- **expiretime=***EXPIRETIME*

  *set the maximum age in seconds of valid packet switching entries*

- **if=***INTERFACE*

  *set the (real) network interface to use.*

## EXAMPLES

**vxvde://239.0.0.1**\
 *This vde\_plug\_url refers to the vxvde network defined on the multicast address 239.0.0.1, vni=1.*

*Programs using*\
 **vxvde://ff15::3/port=12345/vni=42**\
 *join the same vxvde network defined by the multicast address ff15::1, port 12345, vni is 42.*

*Virtual Distributed Ethernet is not related in any way with* *www.vde.com ("Verband der Elektrotechnik, Elektronik und Informationstechnik"* *i.e. the German "Association for Electrical, Electronic & Information* *Technologies").*
