To update this thread, for the most part the design of using 2 NICs with 2 Default Gateways is working fine. Like Denny said, we cannot have clients in the same VLAN as the CORE NIC. We created a new VLAN to keep the CORE NICs and that took care of the routing issues. From Windows point of view, I bound only the CORE NIC for any Microsoft Specific Netbios, Domain and File and Print Services. Also from within IIS, we bound all of the websites to the IP Addresses on the F5 NIC, so the application traffic always originates and terminates at F5 NIC.
In spite of all of this, I still have one issue where some of the websites make web service calls to themselves and these web services URLs are using the alias that points to the VIP. Its a scenario, where a pool member is trying to access its own VIP from the same box. For now, I am working around this problem but making a hosts file entry on the pool members to point to the local F5 NIC's IP instead of going to the DNS and resolving to VIP. This seems to be working fine, except its an additional step and dependency.
