Use cEdge as Gateway between MPLS and public internet

Is it possible for the following to work? Basically I'd like to see if its possible to use a cEdge as an internet gateway for the underlay.

 

Topology

Internet---DMZ---cEdge-----MPLS network ----- multiple vEdges

 

Ideally, the internet facing cEdge interface should be in a service VPN and be used to get production VPN traffic along with underlay MPLS traffic to the DMZ.

For now, my only idea is to leak the default from the service VPN into VPN0 and advertise the default on the MPLS network but it isn't working. Any idea on how to make this work or alternate suggestions?

Hello,

 

What version of CSR100V are you using? I think is a version issue. I solved it by using the supported version 16.12:

Best regards,

Feel like I'm close. To making this work. Any advice?

 

I went down the path of using a loopback for the connections and binding it to a physical interface using the below config but I get the following error with the below config.

 

interface GigabitEthernet1

   no shutdown

   ip address dhcp  i

interface Loopback0

   ip address 192.168.0.1 255.255.255.255

interface Tunnel0

   no shutdown

   ip unnumbered Loopback0

   tunnel source Loopback0

   tunnel mode sdwan

sdwan

   interface Loopback0

    tunnel-interface

     encapsulation ipsec weight 1

     bind GigabitEthernet1

 

tunnel-interface bind': The bind interface GigabitEthernet1 must be a valid physical interface
