| Verify Single to Multi Point intents |
| NOTE:If main.hostsData is not defined, variables data should be passed in the |
| same order index wise. All devices in the list should have the same |

| eg. hostName = [ 'h1', 'h2' ,.. ] |

| Description: |
| Verify add-multi-to-single-intent |
| Steps: |
| - Get device ids | ports |
| - Add multi to single point intents |
| - Check intents |
| - Verify flows |
| - Ping hosts |
| - Reroute |
| - Link down |
| - Verify flows |
| - Check topology |
| - Ping hosts |
| - Link up |
| - 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: |
| onosNode - ONOS node to install the intents in main.CLIs[ ] |
| 0 by default so that it will always use the first |
| ONOS node |
| 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 |
