+This test verifies connectivity in face of dynamic configuration and Onos failures using SegmentRouting
+
+It consists of
+
+1) Configure and Install ONOS
+2) Start Mininet and check flow state
+3) Connectivity test
+4) Add Hosts dynamically
+5) Connectivity test
+6) Onos Failure
+7) Remove host configuration
+
+Requirements
+
+ - An updated version of the CPQD switch has to be running to make sure it supports group chaining.
+
+The test is executed using the netcfg subsystem:
+    1) APPS=openflow-base,netcfghostprovider,netcfglinksprovider
+The test runs for different topologies:
+ - 2x2 Leaf-Spine and 3-node ONOS cluster
+ - 4x4 Leaf-Spine and 3-node ONOS cluster
+ - Single switch and 3-node ONOS cluster
