[CentOS] setup VLAN without primary LAN?

2009-06-25 Thread mcclnx mcc

we would like setup VLAN on CENTOS 5.X and 4.x.  Only VLAN will active, but 
primary LAN NOT active.  E.g eth0 inactive, but eth0.2 active.

I have been tried several ways, but never successful.  

Any ideal?

The primary interface has to be up, but it doesn't need to have an IP
address assigned.  If it does, it would be for the 'native' (untagged) vlan.

I have a host that is running IPv6 on a number of VLANs on eth1, as it 
is my RADVD server.  There is no addressing on the 'default' VLAN:

ifcfg-eth1:

# Intel Corporation 82557/8/9/0/1 Ethernet Pro 100
DEVICE=eth1
BOOTPROTO=none
HWADDR=00:50:8B:A5:17:0B
IPV6INIT=yes
IPV6_AUTOCONF=no
ONBOOT=yes
DHCP_HOSTNAME=xxx.htt-consult.com
VLAN=yes


Whereas  ifcfg-eth1.11:

# Intel Corporation 82557/8/9/0/1 Ethernet Pro 100
DEVICE=eth1.11
BOOTPROTO=none
IPV6INIT=yes
IPV6_AUTOCONF=no
ONBOOT=yes
VLAN=yes
IPV6ADDR=::3:0::180
