Description

1. advance zone. Create guest network with VLAN with different subnets:

VLAN 1250

gateway start IP end IP subnet mask
------------------------------------------------------------------------------------------------------------
10.223.125.1 10.223.125.10 10.223.125.13 255.255.255.192
10.223.125.65 10.223.125.66 10.223.125.68 255.255.255.192

2. Create 3 VMs in this guest network. The 3 VMSs and Virtual Router exhausted the 4 IPs
3. Create 4th VM failed. It should have succeeded with IP in the second IP range.

4. Delete second IP range. Add new IP range to first subnet:

gateway start IP end IP subnet mask
------------------------------------------------------------------------------------------------------------
10.223.125.1 10.223.125.10 10.223.125.13 255.255.255.192
10.223.125.1 10.223.125.15 10.223.125.16 255.255.255.192

5. Create 5th VM succeeds with IP allocated in second IP range.

6. Delete 5th VM. Delete second IP range.
Add second IP range with different subnets:

gateway start IP end IP subnet mask
------------------------------------------------------------------------------------------------------------
10.223.125.1 10.223.125.10 10.223.125.13 255.255.255.192
10.223.125.129 10.223.125.130 10.223.125.133 255.255.255.192

7. Create 6th VM Failed.
