Subject [jira] [Commented] (CLOUDSTACK-9639) Unable to create shared network with vLan isolation
Date Wed, 21 Dec 2016 10:32:58 GMT


ASF GitHub Bot commented on CLOUDSTACK-9639:

Github user murali-reddy commented on the issue:
    a small side note. User can create a guest VM with nic's in two networks with same CIDR
but different VLAN isolations and mess-up routing.

> Create shared network fails with error While creating a shared network it fails to create
with Error "The new IP range you have specified has overlapped with the guest network in the
zone: XYZ. Please specify a different gateway/netmask"
> Steps to Reproduce:
> ===============
> Create an isolated network with a subnet eg:
> Create a shared network with the same subnet but different VLAN, we should observe this
> ===================
> It shouldn't restrict the creation of guest network's with same subnet as long as they
are segmented by VLAN.
> ================
> It doesn't allow the creation of shared guest networks if there is any isolated guest
network using the same subnet although it allows using the same subnet in multiple shared
