Site to Site VPN with MPLS as Primary Connection

I followed the documentation setting up the connection but the MPLS connection on WAN 2 of the MX doesn't ever say connected.  Configuring Site-to-site VPN over MPLS - Cisco Meraki

 

Design

Data Center at HQ has a core switch with a VLAN 700,701 each have an assigned IP address on those interfaces.  Have one port on this switch configured as a TRUNK port that connects to our ISP for our MPLS. Both remote sites are using this one port with 2 different vlans. 

 

Remote Sites - First remote site has a MX and with an internet connection that is working over the Site to site VPN - WAN 1 connecting back to a VPN concentrator at HQ.  On WAN2 I configured this port to have a static IP for VLAN 700.  This connection never comes up.  

 

I previously had a L3 switch at the remote site that had a trunk port with a native vlan set to 700 and an IP address assigned to the vlan 700 interface.  Default route back to the HQ vlan 700 interface IP.  

 

Am I required to still have a L3 switch on the remote side so the MX connects into a access port on the switch? Or can it connect into trunk port from the HQ going across the MPLS connection.

Little tough to follow without a diagram. But, in general if the MX WAN interface shows as down then it means it cannot reach dashboard. Does that interface have a proper route & NAT to reach internet/dashboard?

I assumed it did but after thinking about it a little hard that network that I created for the interconnect isn't allowed through the firewall.  I will be enabling this later today to and will report back my finding.
