-        *   Install 198.51.100.0/24 to NextHopGroup containing one NextHop which
-            is a static route to the ATE LAG port containing ports 2-3, and
-            override the destination MAC to a specified value.
-
-        *   Forward packets between ATE port-1 and ATE LAG (destined to
-            198.51.100.0/24 i.e. packets with destination IP starting
-            198.51.100.1 up to 198.51.100.255) and determine that packets are
-            forwarded successfully.

-        *   Disable ATE port-2 and forward packets between ATE port-1 and ATE
-            LAG (destined to 198.51.100.0/24 ) and determine that packets are
-            forwarded successfully.

+            of the LAG.
+        *   The gRIBI NH entry uses 192.0.2.22 to select the LAG as the egress
+            interface.
