PFSense - Equal Cost Multi-Path Routing with Carp

[Daeta]

We're trying to build some fail over into our new co-location facility.  I was asked questions by the Data Center that had me for a loss.

Currently we are using just one PFSense box with a single WAN connection.

In our new facility we are going to have 2 WAN connections.  I was asked if we were going to have devices capable of doing "Equal Cost Multi Path Routing"  Can the PFSense do this. while utilizing 2 routers?

My thought was to have the 2 internet connections come into 2 switches which then feed into the 2 PFSense machines.  With one /27 Network for us.  But we will have 2 gateways.

I have uploaded the copy of the Visio doc they sent me.  (IP addresses changed to protect the innocent)

Is there a guide that you can point out that would assist me with this?

Thanks!
