Anthony Xu resolved CLOUDSTACK-4282.
------------------------------------
Resolution: Fixed
> [SharedNetworks] Unable to create multiple shared networks with different
> VLAN but with same CIDR
> -------------------------------------------------------------------------------------------------
>
> Key: CLOUDSTACK-4282
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4282
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Network Controller
> Affects Versions: 4.2.0
> Environment: commit id # e6d03f2322822aee331a1a2aa60190c4c755c402
> Reporter: venkata swamybabu budumuru
> Assignee: Anthony Xu
> Priority: Critical
> Fix For: 4.2.0
>
> Attachments: logs.tgz
>
>
> Steps to reproduce:
> 1. Have latest CloudStack setup with at least 1 advanced zone.
> 2. Create a shared network with the following details using the
> defaultSharedNetworkOffering
> VLAN : 1200
> gateway : 1.1.1.1
> startip : 1.1.1.100
> endip : 1.1.1.110
> 3. Create another shared network with different VLAN but with same above
> subnet
> VLAN : 2361
> gateway : 1.1.1.1
> startip : 1.1.1.100
> endip : 1.1.1.110
> Observations:
> (i) It fails with the following error
> The IP range with tag: 1200 in zone zone1 has overlapped with the subnet.
> Please specify a different gateway/netmask.
> (ii) Ideally, it should let admin create multiple shared networks with same
> subnet when the corresponding VLAN ids are different.
> Attaching all the required logs along with db dump to the bug.
> *** Marvin tests for shared networks are failing due to the above issue.
> Here is one such test failure
> integration.component.test_shared_networks.TestSharedNetworks.test_createSharedNetwork_usedVlan2
> (from nosetests)
> Failing for the past 2 builds (Since Unstable#133 )
> Took 0.25 sec.
> Error Message
> Execute cmd: createnetwork failed, due to: errorCode: 431, errorText:The IP
> range with tag: 1200 in zone Adv-KVM-Zone1 has overlapped with the subnet.
> Please specify a different gateway/netmask.
