Vlan Tagging with bonding network interface on RHEL4

This is not a simple task, as there are few things which should actually happen for it to work.

First – the switch port should support vlan tagging (of course, right?)

I have used vlan2 for “external” network, and vlan3 for “internal” network.

My configuration looks like this:

ifcfg-eth0:

DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
ISALIAS=no

ifcfg-eth1:

DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
ISALIAS=no

ifcfg-bond0:

DEVICE=bond0
BOOTPROTO=none
ONBOOT=yes

ifcfg-bond0.2:

DEVICE=bond0.2
BOOTPROTO=static
IPADDR=1.2.3.4
NETMASK=255.255.255.0
ONBOOT=yes
VLAN=yes

ifcfg-bond0.3:

DEVICE=bond0.3
BOOTPROTO=static
IPADDR=192.168.0.1
NETMASK=255.255.255.0
ONBOOT=yes
VLAN=yes

I hope it helps anyone who is into vlan tagging over bonding interfaces.
