How many pfSense can I apply CARP to
-
Hi all, I have this problem, I already have 2 pfSense in CARP with 4 interfaces each machine, but I need to apply CARP to other 4 pfSense with 3 interfaces each, but they are not phisically near the first 2. And these other 4 should be master as well. So the thing is there would be a cluster with 5 masters and 1 backup. All the masters would not be each one near the other, they would be in different cities, and through a fiber cable they get to the same switch but in different networks, where the first master and backup are plugged. So would I need more interfaces in the backup?? can I use a switch or router to connect these others masters? ty

CARP only supports one master for any one group (at this time), I think you can have multiple backups.
You probably want to look into OSPF for your setup.

If CARP interfaces don't match in same network segments it make no sense to "carp" over both networks ?
I can guess what you want - as our 2 office setup it would be nice to configure with 1 Master "configuration" machine both places with each master/slave failover.
But on the other hand it's better to have both places their own CARP regulation because you can have only up to 256 CARP addresses per Setup => on /24 and your finished ;)I've found here in forum some weeks ago a hint that there is a plan (sometimes in this century? ;)) to deploy a "cluster"-configuration tool for pfsense so that many pfsense clusters can managed at one place… that would be great ;)
