Issue

• How to create a bridge using a tagged vlan (8021.q) interface?

Resolution

• Create the VLAN interface (here using eth0)

# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
HWADDR=XX:XX:XX:XX:XX:XX
ONBOOT=yes
USERCTL=no

# vi /etc/sysconfig/network-scripts/ifcfg-eth0.# (Where # is the vlan ID)

DEVICE=eth0.#
ONPARENT=yes
TYPE=Ethernet
VLAN=yes
USERCTL=no
BRIDGE=br0

• If using DHCP,

# vi /etc/sysconfig/network-scripts/ifcfg-br0

DEVICE=br0
TYPE=Bridge
BOOTPROTO=dhcp
ONBOOT=yes
DELAY=0

• If not using DHCP,

# vi /etc/sysconfig/network-scripts/ifcfg-br0

DEVICE=br0
TYPE=Bridge
BOOTPROTO=static
ONBOOT=yes
IPADDR=<IP>
NETMASK=<SUBNET MASK>
DELAY=0

• After modifying these files a restart of the network service is needed.

# service network restart
