Capability vrf-lite

Hi,

I am trying to understand the concept of "capability vrf-lite" but couldn't
simply get it. I was reading on the internet and everywhere they are talking
about DOWN bit and stuff

Can anybody explain why is it needed? Suppose we have CE1-PE1-PE2-CE2
connectivity with PE-CE protocol as OSPF with same process-ID and MP-iBGP in
the core. Technically speaking if process-IDs are same then domain-IDs are
equal, therefore intra-area and inter-area routes should appear as
inter-area routes on the remote CE, while external routes will show up as
external on the other side.

So again, where and why this feature is required?

Thanks,
Malik
