Yeah everything is up / up
But I feel "vrf " is not allowing to send routes between areas..not sure..

hmm... vrf's, are you studying for R&S? :)
anyway, check if you have "ip vrf forwarding GIT" on all interfaces that you
are trying to advertise on R1 with these network commands:
> network 172.22.80.180 0.0.0.3 area 0
> network 192.168.1.17 0.0.0.0 area 0
> network 202.63.64.0 0.0.15.255 area 0 network 202.130.192.0
> 0.0.31.255 area 0 network 203.89.96.0 0.0.31.255 area 0
and are they all up/up?
