I will ask you something here to explain 
R1-R2 
in R1 and R2 there are many same VRF, and there is one link between R1 and R2, how we config this Link??

Hi @MHM Cisco World,

as i think we can do it after making subinterfaces on the physical interfaces..

[MHM Cisco World]

if we have 100 VRF ? how many subinterface?

[MHM Cisco World]

if you not use VRF-lite you need 100 subinterface each one have it IP 
with VRF-lite 
you need one interface IP and you can add 100 VRF to this link with one IP. 

that is the different.

Yes, the "lite" version often does not have the "capacity" or all the "features" of the non-lite version.  For example, lite might not support as many VRF instances and/or might not support VRF using MPLS.

good difference here :

depends on use case you can configure on ISR
