Virtual IP over bond (aggregated) Network?

Alzhy — Tue, 20 Apr 2010 13:51:59 GMT

I did this:

cp -p ifcfg-bond0 ifcfg-bond0:1
edited ifcfg-bond0:1 (to reflect the IP address)
plumbed up the VIP device:
ifconfig bond0:1 xxx.yy.pp.qq netmask 255.255.255.0

Is this correct?

TIA!

Shalom,

This is a legitimate and correct use. There is no reason why you can not have two IP addresses or more associated with a bond address.

I've done this in the past.

Don't test it on a production server, try it out first in the lab though. There are occasionally bugs with network bonding that can lead to unfortuneate results with certain kernel/hardware combinations.

Yes

What I meant was it must be right, that is how I did it.

In fact, you should:

cp -p ifcfg-bond0 ifcfg-bond0:1
edit ifcfg-bond0:1 (to reflect the IP address)
edit ifcfg-bond0:1 (to reflect the device DEVICE=bond0:1)
Run:
ifup bond0:1
