pinging loopback of other AS router :
ping 2.2.0.4 ------------ No reply.
ping 2.2.04 source lo0 ------ reply.
What would be the reason?

hi,
i might be wrong here but i think that 2.2.0.4 does not have a route back to the specific address you are pinging from .
if you do a "debug ip placket" on the router that is pinging 2.2.0.4, you should be able to see what interface you are using as a source ip.
rmy guess would be that 2.2.0.4 does not have a route back to that source ip.
also check if you have all the routes you see above in the routing table as well as the bgp table.
HTH , sorry if i am pointing out the obvious
How you are advertising these routes? Can you check the next-hop reachability?
HAPPY STUDY

pinging loopback of other AS router :
ping 2.2.0.4 ------------ No reply. (the router owning the interface 2.2.0.4 does not have a route back to the subnet where your pinging source interface belongs to)
ping 2.2.04 source lo0 ------ reply. (the router owning the interface 2.2.0.4 has a route back to your loopback)
If you are running BGP, then you may have advertised only your loopback and not your connected interfaces .... it all depends on your topology and your configuration
