I have two different locations that are connected by a VPN link.
I want both locations to work even if the other side goes down.
I'm unsure what should I do?
# Publisher + Subscriber?
Will subscriber authenticate users when publisher is down?
Will OnGuard work? (requires health to be written to db?)
Will [Machine Authenticated] work for new machines? (requires role to be written to db?)
# Publisher + Standby Publisher?
if the link goes down, both Publishers will become active. What happens when the link goes up again?
Can I do automatic failback so that after the link comes up the promoted publisher gets back to standby?
Another related question:
Will data that I insert to the database using appexternal also get replicated from Publisher to Subscribers?
- Is it possible to have centralized accounting on the Publisher?
This interests me too. We have two separate locations too so can't have virtual IP for Clearpass servers.
Wondering also if I should relay DHCP to both servers or will it mess up the profiling?
Please take a read of the following document.
