'''
Description: Validate Ping between 2 VMs in the same VN, 2 VMs in different VN
subnets.
Test steps:
1. Create 1 IPAM's.
2. Create 1 VN with 2 subnets and launch 2 VMs in them.
3. Ping between the VMs in the same VN should go thru fine.
4. Ping to the subnet broadcast and all-broadcast address.
Pass criteria: VM in the same subnet will respond to both the pings, while the VM in a different VN should respond only to the
all-broadcast address.
