Hi everyone. I need some guidance here which I hope you can help with.

I am trying to configure a simple MPLS VPN "cloud" with IPSec VPN as a backup. There should only be a single CE router at each site to handle this.

Is anyone able to provide a simple sample config and network diagram to illustrate this?

TIA!

You need a VPN gateway in MPLS Core for tunnel creation (PE-CE).
Create tunnel (in GNS GRE should be OK, in real life IPSes protection is a must) in a usual way, CE routes all traffic via Tunnel interface, either via static route or any dynamic routing.
On MPLS core, put Tunnel interface in appropriate VRF and create proper RD - like you did with Eth/Serial interfaces.
It is nothing special, we just operate on virtual (TunnelXX) interfaces.

Hi abort, thanks for your response! I am still learning on VPNs so bear with me here.

Does the IPSec VPN traffic gets routed through the LSRs as well? I would really appreciate if there is a sample topology as I'm more of a "visual" guy.

Thanks!
