In this scenario (which is admittedly a lab environment) you cannot disable
synchronization. A, B or C cannot advertise any transit routes to their
respective EBGP peers unless those routes are installed in the IGP as well.
The idea behind synchronization is that if a transit network's interior
routers can use the transit networks its advertises, then there should be no
"black holes".
