Traffic stuck at Route Reflector

[emurray]

I am studying for the CCNP Service Provider and I am trying to understand the Route Reflector design and configuration regarding MPLS LDP.  I have read that the Route Reflector does not need MPLS with LDP since is not part of the forwarding plane. But if you have the Route Reflector in the middle, the traffic will have to pass through the Route Reflector.

In that case, the RR should have MPLS LDP configured?

In my lab, I configured the RR without MPLS, and the traffic is stuck at the route reflector. In the picture submitted, if do a trace from PE01 Loopback on the left to PE02 Loopback on the right. I can't get past P1. 

Does that mean I would need to configure MPLS LDP in the RR in my design or do I have a design or config error?

Any help is welcome

Hi @emurray ,

Yes you need to configure LDP on the route reflector if it is in the forwarding path. In production networks, the RR is normally not in the forwarding path, hence no need to configure LDP on it.

Thanks for the clarification. I was almost sure that was the case.
