+This test verifies the segmentrouting application to be working correctly when changing the interface configuration at runtime.
+
+It consists of
+
+1) Configure and install ONOS cluster
+2) Start Mininet and check flow state
+3) Pingall
+4) Change the configuration of a certain interface
+5) Pingall
+
+<h3>Requirements</h3>
+ - Trellis leaf-spine fabric: please visit following URL to set up Trellis leaf-spine fabric
+ https://github.com/opennetworkinglab/routing/tree/master/trellis
+ - ONOS_APPS=drivers,openflow,segmentrouting,fpm,netcfghostprovider
+
+<h3>Topologies</h3>
+- 0x1 single ToR
+- 0x2 dual-homed ToR
+- 2x2 leaf-spine
+- 2x4 leaf-spine with dual-homed ToR and dual links to spines
+- 2x5 topology with spines S0 and S1, and leafs L0, L1, L2, L3, L4.
