OpenVPN + quagga OSPF how to?

[elementalwindx]

I'm not new to OpenVPN but I am new to Quagga. Can someone help direct me in a how-to manner in setting up Quagga?

I've got Quagga installed on both pfsense boxes.

The scenario: 2 offices

Office A (Server):
WAN - Cable internet
DSLGW - DSL internet

Office B (Client):
WAN - Cable internet

I have setup OpenVPN server on Office A with 1194, TCP, TUN, shared key, listening on localhost.
I have setup OpenVPN client on Office B with same settings except advanced settings filled in: remote my.ip.address.here 1194 tcp-client

I want to make it so that when a internet connection goes down at the server, the client can still connect.

How do I go about doing this?

Thanks!

edit

After much reading it looks like OSPF is not something you'd use in this scenario but rather only if both Offices had 2 WAN connections. Am I correct? If so, then what do you use to make transitions from down'd connections smoother?
