Vlan issue - main interface keeps getting an IP address
I just setup vlans on my main server as I want to be able to bridge VMs to various vlans.
For some reason the main interface keeps getting the same IP as the main vlan (the one that is used to access the host). See here:

On a side note how do I disable the other interfaces from getting an ipv6 IP? I don't want them to be routable in any way shape or form, they are strictly there so I can bridge VMs to them (have not tested this yet but going to home/assume this works the way I think).
Here is the config for eth0:
ifcfg-eth0
Quote:
# Intel Corporation 82566DC-2 Gigabit Network Connection
DEVICE=eth0
BOOTPROTO=none
#BROADCAST=10.1.1.255
HWADDR=00:1c:c0:41:8f:97
#IPADDR=10.1.1.10
#NETMASK=255.255.0.0
#NETWORK=10.1.0.0
#GATEWAY=10.1.1.1
ONBOOT=yes
#NM_CONTROLLED=no
TYPE=Ethernet
|
Here is the config for eth0.2 (main vlan where server "resides" and is managed/accessed from)
ifcfg-eth0.2
Quote:
VLAN=yes
DEVICE=eth0.2
BOOTPROTO=static
ONBOOT=yes
TYPE=Ethernet
IPADDR=10.1.1.10
NETMASK=255.255.0.0
GATEWAY=10.1.1.1
|
If I change the IP of eth0.2 eth0 gets that IP. If I turn off eth0 it turns off all the vlans.. guessing this is normal behavior though. |
