CARP - Multiple CARP addresses or IP Aliases?
Ok so I have our main carp setup working in a beautiful fashion. Very nice stuff this!.
Now comes the time where I need to add more IPs to our public interface. We have a /22 from the ISP and the carp setup is using /22 correctly.
So, I've been advised to use IP Aliases to add the rest of the IPs, and not setup seperate carp records for them as each carp record uses broadcast/multicast to advertise itself.
Is this correct, I should use IP Aliases?
Can you monitor the status of the IP Alias the same way you can monitor which box a CARP address is on?

It's a brand new option that works fine.
To get it working, on ip alias gui select your working carp interface instead of wan,lan,etc.
If you have two systems setup, all your VIPs must be CARP. IP aliases are only on the primary, can't have them on two systems as they cannot be shared.
