Site 1- Controller Site 2 - Controller
Guest Vlan x Guest Vlan x
Need help with setting up the above topology whereby we have two sites controllers and two Master/Backup controller separated by layer 3 network. The requirement is to tunnel (GRE) Guest VLAN from site 1 and 2 to active Master controller at DC1 and automatically failover to Master -Backup controller at DC2 in the event DC1 controller goes down. Is this possible. Help , highly appreciated. Thanks
