[jira] [Commented] (CLOUDSTACK-6430) [SDN] CS asks for vlan range
even we create physical network with GRE isolation and uses those ranges as
GRE keys in creating tunnels

Murali Reddy commented on CLOUDSTACK-6430:
------------------------------------------
Movie it out of 4.5 to future. This is more of enhancement for above mentioned reason.

> [SDN] CS asks for vlan range even-though we create physical network with GRE isolation and uses those ranges as GRE keys in creating tunnels
> Steps to reproduce:
> ================
> 1.Install CS with latest build from 4.4
> 2.During zone creation choose GRE as the isolation method and proceed further
> 3.Zone creation wizard asks to specify vlan range so give some range there
> 4.Proceed to complete zone creation
> 5.Create an isolated network with stretched-l2 service.
> 6.Deploy guest vms in the network and make sure that vms in that network are spanned across the hosts in the cluster
> Observations:
> ===========
> When the vms are created on more than one host in the cluster CS programs GRE ports on the ovsswitch on all the hypervisors on which the vms are running and it uses the one of the vlan from the vlan range given during zone creation.
> Expected Result:
> ==============
> 1.When physical network is created based on GRE isolation CS should not ask for the vlan range
> 2.GRE key should be picked up randomly so that user does not have to provide any range even for the GRE keys.
> In my setup I had provided vlan range as 981-1000 and the following are the GRE tunnels info from the hypervisor:
> Bridge "xapi3"
> fail_mode: standalone
> Port "t983-1-5"
> Interface "t983-1-5"
> type: gre
> options: {key="983", remote_ip="10.147.40.31"}
> Port "vif5.0"
> Interface "vif5.0"
> Port "t983-1-4"
> Interface "t983-1-4"
> type: gre
> options: {key="983", remote_ip="10.147.40.14"}
> Port "xapi3"
> Interface "xapi3"
> type: internal
> ovs_version: "1.4.6"
