MPLS loop

Hi,

I'm studying for the JNCIS-SP and have set up a home lab. I'm currently stuck trying to configure a l3vpn and would appreciate any help.

My core uses OSPF for its IGP. Full iBGP mesh. RSVP LSPs.

My CE routers connect to PE using eBGP.

VRFs and MP-BGP is all up and running and my CEs are receiving and accepting routes advertised from remote CE.

So where I am stuck is getting traffic to pass from one CE to the other via LSP.
I currently have only 1 LSP in each direction between my PEs.

I'm not totally clear on the method to ensure the traffic from CE-CE uses the LSPs, so I used the install prefix on each PE LSP to install destination prefix.

I can't ping from CE-CE.

When I try traceroute MPLS <LSP-name> detail I appear to get a loop.

There is no equivalent loop when using IGP to ping between PEs.
I am using CSPF.
Have tried strict hop EROs and verified that the LSPs are using the correct path.

Can anyone help?
