def _get_network_instance(self):
return self.__network_instance<EOL>
Getter method for network_instance, mapped from YANG variable /network_instances/network_instance/policy_forwarding/policies/policy/rules/rule/action/config/network_instance (leafref)

    YANG Description: When this leaf is set, packets matching the match criteria
for the forwarding rule should be looked up in the
network-instance that is referenced rather than the
network-instance with which the interface is associated.
Such configuration allows policy-routing into multiple
sub-topologies from a single ingress access interface, or
different send and receive contexts for a particular
interface (sometimes referred to as half-duplex VRF).
