Hello Ivan,
You could use a topology like this:
In that example, I have redundant P and PE routers but I didn’t use MPLS there. What you need for MPLS VPN is:
- The P routers only run an IGP and MPLS on the interfaces so that’s straight-forward.
- The PE routers require a full mesh of iBGP for the VPN routes but you could also use a route-reflector instead. Both interfaces that connect to the customer are in the same VRF.
If you can configure a MPLS VPN topology without redundancy then it’s easy to add redundancy, there are no extra commands. If you have trouble with this, let me know and I’ll share the configs when I get back from my holiday (next Wednesday)
