Exhibit:

There is no direct physical connectivity between Domain 3 and Domain 5. The Transit AS 65102 is only running partial-meshed IBGP between Domain 3 and Domain 5 and is using OSPF as its IGP. Both Domain 3 and Domain 5 are using the next-hop-self options. The external BGP routes are not being redistributed into OSPF. BGP synchronization is disabled.
What happens to the packet from AS 65101 to AS 65103?

A.
Packets will be black-holed because it will be dropped by Domain 4.

B.
Packets will be black-holed because it will be dropped by Domain 5.

C.
Packets will be black-holed because it will be dropped by Domain 6.

D.
Packets can be transported via the Transit AS 65102 without any problems.

Explanation:
Even with synchronization off testing 6 does not know how to route the packet because OSPF does not know about the route that BGP knows about. Synchronization being off assumes that there is a full mesh of BGP routers.
