Cisco ASA 5510 Route Problems

I am trying to accomplish the following and keep getting the error "Cannot add route, connected route exists"

I have 2 Inside Interfaces labeled (inside, inside_2)
I have 2 dual ISP WAN Interfaces (CCCharterWAN, CCTelepacificWAN)

I am trying to have "inside" go out the "CCCharterWAN"
and
"inside_2" go out "CCTelepacifiicWAN"

What am I missing??

Unfortunately the asa does not support the setup you are describing. The asa only supports dual ISP failover not load balancing. Take a look at the link below for a clear explanation and possible alternatives;

I don't need load balancing. I need each inside and inside_2 interface go out separate WAN interfaces.

You could do this with 2 contexts which makes the firewall behave as 2 different firewalls.

In single context mode, there is 1 routing table. You will then only have 1 default route out which all traffic will go.

The 5510 supports 2 different contexts without additional purchase. In multiple context mode, you have a routing table per context, BUT you will then loose a load of other features. See the below taken from the 9.1 configuration guide.

Multiple context mode does not support the following features:
• RIP
• OSPFv3. (OSPFv2 is supported.)
• Multicast routing
• Threat Detection
• Unified Communications
• QoS
• Remote access VPN. (Site-to-site VPN is supported.)
