L3 MPLS issues - Juniper

I have no problems getting the equivalent working with Cisco but im having some issues transferring this to Juniper.

Anyone familiar with Juniper able to take a look at my config?

CE's have a route to each other (learnt via BGP from the PE, and PE has the route in its table for the relevant VRF)

The issue is with the PE config somewhere as that is as far it the trace gets.

CE1--PE1--P--PE2--CE2

PE1 config:

set version 12.1R1.9 set system root-authentication encrypted-password "$1$w5W3Qxul$hvWK6vFpzbsoC3hCmKEMN/" set system syslog user * any emergency set system syslog file messages any notice set system syslog file messages authorization info set system syslog file interactive-commands interactive-commands any set interfaces em0 unit 0 family inet address 192.168.12.2/24 set interfaces em1 unit 0 family inet address 192.168.23.2/24 set interfaces em1 unit 0 family mpls set interfaces lo0 unit 0 family inet address 2.2.2.2/32 set routing-options router-id 2.2.2.2 set routing-options autonomous-system 65000 set protocols mpls interface em1.0 set protocols bgp group pe type internal set protocols bgp group pe local-address 2.2.2.2 set protocols bgp group pe family inet-vpn any set protocols bgp group pe neighbor 4.4.4.4 set protocols ospf area 0.0.0.0 interface lo0.0 set protocols ospf area 0.0.0.0 interface em1.0 set protocols ldp interface em1.0 set routing-instances CustA instance-type vrf set routing-instances CustA interface em0.0 set routing-instances CustA route-distinguisher 2.2.2.2:1 set routing-instances CustA vrf-target target:65000:1 set routing-instances CustA protocols bgp group ce type external set routing-instances CustA protocols bgp group ce peer-as 65100 set routing-instances CustA protocols bgp group ce neighbor 192.168.12.1 

This is all in a lab environment right now via Olive's

Routing table of CE-1 (loopback of CE-2 is 5.5.5.5):
