Vlan 15 - 20 -----192.168.x.1 / 24 onwards ( where x corresponds to the VLAN number)
Vlan 50 - 192.168.50.y / 24 (where y corresponds to end host IP address)
I want to place the ASA 5520 between Cisco 65xx & the servers, in Active - Active mode.
One of the requirement of Active/Active mode is the need to configure Multiple contexts in the firewall. For multiple context, each context typically uses a different subnet. You can use overlapping subnets, but your network topology requires router & Nat configuration to make it possible from a routing standpoint.
Is it possible configure transparent mode (active ? active failover) without multiple contexts within 192.168.50.y network? If yes, how & If not, what are the possible alternatives to implement the ASA between the Core 65xx switch (VLAN 50) & the servers (192.168.50.y), in active / active failover mode?
