Around 10% packet loss when I ping inside a VRF but 0 loss when I ping in the global routing table

Hi,

Subject covers the issues but here is me pinging from a CE > PE and PE > CE. Thought it was an MTU issue but I still get the same amount of loss (around 10%) in the VRF whether MTU is default or 128 and 0 loss from the non-VRF P2P address range. Any advice?

Both routers are LDP speaker.

CE uplink:

interface GigabitEthernet0/0 mtu 1524 ip address 10.255.255.254 255.255.255.252 no ip redirects no ip unreachables no ip proxy-arp ip mtu 1500 ip ospf authentication ip ospf authentication-key 123 ip ospf network point-to-point ip ospf dead-interval 5 ip ospf hello-interval 2 ip ospf mtu-ignore ip ospf cost 5000 duplex auto speed auto mpls mtu 1500 mpls label protocol ldp mpls ip end 

PE downlink:

interface GigabitEthernet0/0/0.104 encapsulation dot1Q 104 ip address 10.255.255.253 255.255.255.252 no ip redirects no ip unreachables no ip proxy-arp ip mtu 1552 ip ospf authentication ip ospf authentication-key 123 ip ospf network point-to-point ip ospf dead-interval 5 ip ospf hello-interval 2 ip ospf mtu-ignore ip ospf cost 5000 mpls mtu 1552 mpls label protocol ldp mpls ip end 

NB: Actually using public IPs for the P2P just changed to 10.255.255.x for obvious reasons.
