-# Equivalent to (using auto-indexing):
-# internal_networks:
-# left:
-# segmentation_id: 2000
-# physical_network: phys_sriov0
-# right:
-# segmentation_id: 2010
-# physical_network: phys_sriov1
+# - mpls_transport_labels is used only when MPLS encapsulation is enabled (mpls: true)
+# this parameter doesn't support auto-indexing because this is not a typical scenario
+# expected the list of values in a range 256-1048575, one value per chain is expected
+#
+# In the bellow configuration example 'segmentation_id; contains the inner MPLS label for each chain
+# and 'mpls_transport_labels' contains the outer transport MPLS label for each chain
+# Example of 2-chain MPLS configuration:
+# internal_networks:
+# left:
+# network_type: mpls
+# segmentation_id: [2000, 2001]
+# mpls_transport_labels: [10000, 10000]
+# physical_network: phys_sriov0
+# right:
+# network_type: mpls
+# segmentation_id: [2010, 2011]
+# mpls_transport_labels: [11000, 11000]
+# physical_network: phys_sriov1
