If this is the case, then stop what you are doing. 2921 router is not designed to push 100 Mbps.
To be able to push 1 Gbps you should be looking at an ASR 1002 with RP2 and ESP 5 as a minimum. Otherwise, you are just wasting money on your WAN when your router is unable to push that much amount of bandwidth.
It is not clear to me exactly what the requirements will be when you cluster your non Cisco firewalls and connect them to your router. Would I be correct in assuming that the requirements include: two physical interfaces on the router both in the same subnet and with a single IP address on the router? Perhaps the easiest way to achieve this would be to put a small switch module into the router, configure a vlan in the switch module assigning an IP address to the vlan interface, assign 2 of the switch ports to the vlan.
I am also not clear how the firewalls will connect to the router. Will each firewall have a direct physical connection to the router? Or is it possible that the firewalls will connect to a switch and the switch connects to the router? If the firewalls connect to a switch then perhaps you need only a single interface on the router?
