This attribute specifies the EGP autonomous system to which routes are
exported to as a result of matching this export policy.
If the attribute advertiseStatus is set to block, then the value of
outAutonomousSystem is ignored. The outAutonomousSystem value is
not used to select which routes to block or send but where to export the
routes.
A value of 0 indicates that the routes are exported to all EGP
autonomous systems of which the virtual router is a neighbor.
Otherwise, the value of this attribute must match the asId of an EGP
neighbor on the same virtual router.
