mpls ip in tunnel interface

Hi group,

Just wondering, what I know is that on an MPLS-TE tunnel interface between
two P routers you need to configure mpls ip because else you end up breaking
the end2end LSP. Are there any other scenarios where you would need to set
mpls ip on the tunnel interface? I am asking because I saw an example in a
forum somewhere, where there was LDP activated on the tunnel interface, but
this was between two PE routers. Only difference was that the tunnel
interface was bound to Lo1 instead of Lo0. But I labbed it and using Lo1 as
tunnel interface without configuring mpls ip on it works just fine when you
do ping <Lo0-PE2> source <Lo0-PE1>.

Cheers,
Florian
