------------------------------------------------------
Summary: [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
Priority: Critical
Fix For: 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 : 1200
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.
