+        format, either all the devices have its port or it doesn't.
+        eg. hostName = [ 'h1', 'h2' ,..  ]

+        Steps:
+            - Get device ids | ports
+            - Add single to multi point intents
+            - Check intents
+            - Verify flows
+            - Ping hosts
+            - Reroute
+                - Link down
+                - Verify flows
+                - Check topology

+                - Ping hosts
+            - Remove intents
+        Required:
+            name - Type of point intent to add eg. IPV4 | VLAN | Dualstack
+            hostNames - List of host names
+        Optional:
+            devices - List of device ids in the same order as the hosts
+                      in hostNames
+            ports - List of port numbers in the same order as the device in
+                    devices
+            ethType - Ethernet type eg. IPV4, IPV6
+            macs - List of hosts mac address in the same order as the hosts in
+                   hostNames
+            bandwidth - Bandwidth capacity
+            lambdaAlloc - Allocate lambda, defaults to False
+            ipProto - IP protocol
+            ipAddresses - IP addresses of host in the same order as the hosts in
+                          hostNames
+            tcp - TCP ports in the same order as the hosts in hostNames
+            sw1 - First switch to bring down & up for rerouting purpose
+            sw2 - Second switch to bring down & up for rerouting purpose
+            expectedLink - Expected link when the switches are down, it should
+                           be two links lower than the links before the two
+                           switches are down
