Hi there,
I have a couple of questions regarding HA fast failover in the following scenario.
2 x 7205 controllers deployed in different datacentres (no stretched VLANs).
First controller configured as Master and 'Active' in HA group.
Second controller configured as Local and 'Standby' in HA group.
As I understand, only one LMS IP is configured (HA active address) and when the AP connects it establishes a tunnel to the secondary controller as well.
What happens if, following failure of the master controller, an AP reboots - it won't be able to communicate with the Master to get LMS IP address? Or does it cache the information about the secondary controller?
Also, in an HA fast failover scenario, will all clients be disconnected when the AP's start to use their standby tunnel? (Egress tunnel is different L3 subnet at each datacentre).
TIA!
