Subject [jira] [Resolved] (CLOUDSTACK-4282) [SharedNetworks] Unable to create multiple shared networks with different VLAN but with same CIDR
Date Tue, 13 Aug 2013 17:31:48 GMT

     [ https://issues.apache.org/jira/browse/CLOUDSTACK-4282?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Anthony Xu resolved CLOUDSTACK-4282.
------------------------------------

    Resolution: Not A Problem

shared networks can access each other in CS, the sub-net associated with different VLAN should
not overrides.

>             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

> 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.
