Hello list,
Here I am today, setting up CARP interfaces on our backup firewalls, and
I'm wondering something...
Let's take the following scenario:
Datacenter PRIM, firewall PRIM:
- carp13 has public IPs X and Y and is master (advskew 100)
Datacenter PRIM, firewall BACK:
- carp13 has public IPs X and Y and is backup (advskew 150)
Datacenter BACK, firewall PRIM:
- carp13 has public IPs X, Y, W and Z (advskew 230, down)
Datacenter BACK, firewall BACK:
- carp13 has public IPs X, Y, W and Z (advskew 250, down)
If I bring up my carp13 interfaces on the backup datacenter, will they
become master because the carp interfaces on the primary datacenter is
lacking 2 public IPs ?
That would be a problem...
Has anyone faced this situation before ?
Also, adding IPs W and Z on my primary datacenter is not an option at
the moment.
