Jeff-
We have done exactly that. We have some services (various ports of
course) using the same VIP. However, we have also set up other
services that need to run on the same ports using a second VIP. One
issue we ran into, though- was that the VIP's configured as aliases
needed to be in the same network block as the RIP on the physical
device (eth0). We found that
in order to add a VIP in a different network block, we needed to
assign another RIP to a physical device, and then alias that second
device for services. Hopefully the example below will make that
clearer:
First set of services:
eth0: 192.168.1.50 <----RIP
eth0:0 192.168.1.100 <--VIP
eth0:1 192.168.1.101 <--VIP
eth0:2 172.30.1.100 <-- VIP ** This would not work
correctly, therefore we configure the second set below-
Second set of services:
eth1: 172.30.1.50 <--RIP
eth1:0 172.30.1.100 <--VIP
eth1:1 172.30.1.101 <--VIP
Then, just reference your VIP's in the config for your software. We
use ldirectord for this.
There are probably different/better ways to do this- setting up static
routes, etc but this solution works for us.
Good luck.
