-----------------------------------------------

             Summary: Ipv6 - Guest Vms are not able to get Ipaddress when executing dhclient
command when using "/96" network.
                 Key: CLOUDSTACK-1232
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1232
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Management Server
    Affects Versions: 4.1.0
         Environment: Latest build from network refactor branch.
            Reporter: Sangeetha Hariharan
            Assignee: Sheng Yang
             Fix For: 4.1.0


Steps to reproduce the problem:

Create a IPV6 network using “/96” CIDR.
Deploy a Vm in this network.

Router assigns an Ipaddress to this VM.
root@r-51-VM:~# cat  /etc/dhcphosts.txt
id:00:03:00:01:06:ce:88:00:00:3c,[fc00:3:1380::9fe5:5d25],vm-1380-1,infinite

But  guest Vms are not able to get the ipaddress.

I see the following in the router logs when , dhclient request is made from the guest.
