Use RevPi modules as a network switch

This application note is available in our GitHub repository as an Ansible playbook.

https://github.com/RevolutionPi/revpi-ansible-recipes/tree/master/roles/network-bridge

You can combine two ports into one bridge. The global functionality is explained here: https://wiki.debian.org/BridgeNetworkConnections#Configuring_bridging_in_.2Fetc.2Fnetwork.2Finterfaces.

An example has been done, and the configuration file located in /etc/network/interfaces has to be edited as below: Using our example names, make it look like this, and you’re set (if you want to use DHCP):

# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# allow-hotplug eth0
# allow-hotplug eth1

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

#This file describes the network interfaces available on your system

#and how to activate them. For more information, see interfaces(5).

#The loopback network interface
 auto lo
 iface lo inet loopback

#RJ45 - Ethernet Port A
 auto eth0
 iface eth0 inet manual
 pre-up ip link set eth0 up
 post-down ip link set eth0 down || true

#RJ45 - Ethernet Port B
 auto eth1
 iface eth1 inet manual
 pre-up ip link set eth1 up
 post-down ip link set eth1 down || true

#Bridge (brctl)
 auto br0
 iface br0 inet dhcp
 pre-up brctl addbr br0 && brctl addif br0 eth0 eth1
 post-down { brctl delif br0 eth0 eth1 && brctl delbr br0 } || true
