+            Enable this flag for the ability to create multiple service chains
+            to the same remote network based on traffic. E.g. http traffic
+            takes one service chain, https traffic takes a different chain.
+
+            The limitation with such networks is that for all service chains
+            that this network participates in,
+            1. If it is the left network, it cannot be extended to the SDN
+               gateway or beyond i.e. all source lie within the DC.
+
+            2. If it is the right network, it cannot be extended to the SDN
+               gateway or beyond unless the last service in the chain is a NAT
+               service. This ensures that return traffic from outside the DC
+               will always go back to the correct service chain.
