when should we enable mpls ip on loopback interface?

Hi all,

 

I need some clarification on enabling mpls ip on lo interfaces. 

1- should we enable mpls ip on lo if the ldp router id is that lo?

2-should we enable mpls ip on lo if all the bgp neighborship is configured over lo? (including P and PE)

3- or should we enable mpls ip under only PE routers?

 

Thanks!
