[c-nsp] VASI NAT with MPLS

[Jason Lixfeld]

Hi,

I’m trying to find some documentation to help me understand if it’s possible to integrate VASI (IOS XE) NAT between two MPLS VPNs.  The examples that I have seen so far seem to imply that a physical interface on the left and right sides, each attached to separate VRFs are required, and my attempts to do this on MPLS interfaces on the left and right sides instead of VRF interfaces have so far been unsuccessful.  My hope is that I can use vasileft and vasiright to stitch together two VRFs, with vasileft being ip nat inside and vasiright being ip nat outside.

Has anyone seen any docs for deployments along these lines in their travels whose links they might be able to share?

Thanks in advance.

Full disclosure - I am testing this in VIRL using CSR1000v nodes because the physical hardware for this deployment will be IOS-XE ASR1002 boxes.  I am assuming the CSR1000v will be an appropriate virtual substitute.
