How to make bridge over VLAN?

Bridging over VLAN's :

By constructing a bridge between a "normal" and a "VLAN" ethernet interface, the Linux computer will add and remove the VLAN headers on behalf of any other device(s) plugged into the "normal" card.

How :

Okay, now for the tricky part. It takes a slight modification of the procedures above. For this example, let's presume we have an Ethernet interface eth0 connected to the network where a VLAN id 2 is present, and we have a device or devices on eth1 that need to be bridged into that VLAN 2.

Go ahead and first construct the VLAN interface like we did before (copy ifcfg-eth#, change DEVICE, add VLAN=yes), except also remove the BOOTPROTO, IPADDR, NETMASK, and GATEWAY lines if present. Add a line BRIDGE=br2 (or a different named bridge device of your choice).

1. vi /etc/sysconfig/network-scripts/ifcfg-eth0.2 (connected to VLAN2)

---
DEVICE=eth0.2
VLAN=yes
TYPE=Ethernet
HWADDR=##:##:##:##:##:##
ONBOOT=yes
BRIDGE=br2
----

2. vi /etc/sysconfig/network-scripts/ifcfg-eth1

--
DEVICE=eth1
TYPE=Ethernet
WADDR=##:##:##:##:##:##
ONBOOT=yes
BRIDGE=br2
---

3. vi /etc/sysconfig/network-scripts/ifcfg-br2

----
DEVICE=br2
TYPE=Bridge
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.2.24
NETMASK=255.255.255.0
GATEWAY=192.168.2.254
DELAY=0
STP=off
---

Note : IP address has in br2

4. service network restart. That's it.

Try :)
