Hi
We have 2 local controllers at 1 of our sites. The master controller is located at another site. I am trying to set up local/local redundancy. There are 2 VRRP Ids each set up on local controllers.
On controller 1 the VRRP config is
vrrp 161
priority 110
ip address 10.x.x.9
description "Initial-Primary"
vlan 19
no shutdown
!
vrrp 162
ip address 10.x.x.8
description "Initial-Standby"
vlan 19
no shutdown
On controller 2 the VRRP config is
vrrp 161
ip address 10.x.x.9
description "Initial-Standby"
vlan 19
no shutdown
!
vrrp 162
priority 110
ip address 10.x.x.8
description "Initial-Primary"
vlan 19
no shutdown
The scenario is that we want to split the APs 50/50 across the 2 local controllers so in the event of a controller failure, the APs will failover to the other controller. When we test this, initially the AP will failover, but as soon as the failed controller comes back up the AP will fail back to the original controller. We do not want this to happen. If the failed controller keeps bouncing, the APs will just keep failing between controllers. We want the APs to failover but stay on the second controller so we can then manually move them back when the controller is fully operational again.
I assumed that not enabling router pre-emption in the virtual router config would mean the AP would failover, remaining on the the new controller until some sort of manual intervention.
Does anyone have any ideas how to achieve what we want?
Thanks
Roy
