Subject: Re: two gateways with one NIC

Well, I found that with CentOS/Fedora/RHEL, I could use their standard
network-scripts to create VLAN devices.

I got VLAN devices running OK, but then ended up in the same boat as
before.

Also, it might be nice if keepalived/LVS had the option of entering a
VLAN device in keepalived.conf? (might come handy for someone one day?)
I just did a bit of a fudge while testing.

My only option, seems only to create a single sided 'active/passive'
KeepAliveD/LVS cluster.

Thanks all for your help :)
