We have a provider that has informed us they configured a MPLS circuit and we need to connect the networks via L2. I am at a loss as how I would need to accomplish this.
Ideally I would like only specific traffic to be passed through the connection as indicated in the diagram.
I would also like traffic to fallback to the VPN in the event the MPLS circuit is interrupted. (this is a nice to have not a need)

There is 2 options you can do as i think of now.
Option1 :
Since you have VLAN 10 over lap each side, is this possible to change any side VLAN 10 LVAN 20,
if yes you can create a L2 trunk to pass VLAN 10 and Vlan 20.
Option2 :
Use different VLAN 30 to extend the Link and create a L3 interface both the side, and run IGP and distribute the network.
(you can also do the Static for the same).
On both the case you can use IPSLA to track the link and fail over to VPN. if L2 MPLS Link Fails.

I have never connected 2 separate networks in this manner. It seems the static route would be the best for our size. How would you recommend accomplishing this?

If you choose to have static routes, you still need IP SLA to track the link and fail over if one it fails.

Hello
just to confirm that topology you posted is or isn’t a true reflection of your actual network?
Is it how you would like to see it or is it how it is currently?
Do you mean L2 vpls?
Whcih is basically extending your l2 vlan domain over two sites so you would have the same vlan subnets being used on each site carrying vlan traffic via this extended L2 connection.
