Do you have a configuration for a mpls tunnel between two routers secured by IPSEC possibly with vrfs? Thank you.

Can you please elaborate on the setup and what you are trying to achieve? Are you refering to MPLS VPN or MPLS TE tunnel. If MPLS VPN, are you configuring your two routers as PE devices? For securing MPLS VPN traffic, IPSec is usually configured on CE devices and the IPSec header will go behind the MPLS header.

Here are the configs for the two PE routers with the mpls tunnel. The traffic in wireshark shows the mpls label but is not encrypted. I would like to do the IPSEC VTI on the PE routers as well as the mpls with the layer 2 tunnel on the Gig 0/1 interfaces. I was hoping there is a way of making a point to point tunnel similar to an encrypted VPLS with the CE routers able to be in the same subnet with no encryption or routing. Thank you.

I do not recall ever coming across configuration that allows you to encrypt MPLS traffic from PE to PE unless you do GRE over IPsec then run MPLS on top of that. Traffic encryption is usually the client responsibility and there is technologies like GETVPN for that.
