CE-6 is behind PE5, 1.1.1.1 and 192.168.12.0/28 are behind PE2.
These two routes go from CE1 to CE6 over MPLS, should they be IA or E2 ?
The above is from my lab, but the video I am watching showing IA.
thanks !!

it should be IA routes since they belong to same Customer.
High level - Why you have different OSPF processes running? Do you run the same OSPF process on both the side - correct and test

I found I missed the following points:

if you like to have different OSPF processes - you can also use domain option on the PE side, so they will be announced the same LSA.
use case like if 2 companies merge and like to keep the existing config on the PE side.
