VCD networking

[ManivelR]

Hi Team,

I have a small confusion here about VCD networking.

1) We have completed the vCloud director setup the without any NSX components(edge gateway--->NAT,VPN,etc..).I mean, We have used NSX manager appliance only to attach VCD with vCenter server.

2) We are using external network only from Organization VDCs to connect the customer VMs to outside world. Assume my external network CIDR range is 10.10.10.0/24.We are using other firewall/LB appliances at outside of VCD to provide some features(like NSX edge gateway-->VPN,DHCP,NAT etc..) to customer.

3) Suppose if want to connect any other VMs from the same subnet(CIDR range is 10.10.10.0/24) or wants to connect the external world(public internet),i will use the same external network to achieve this.

Doubts on this. 

Suppose if i want to use this below option from customer VDC "Create an isolated network within this virtual data center" I need to create a new network pool either with VXLAN backed or VLAN based or vsphere port group-backed.and then needs to attach this network pool in the respective Organization VDCs.

To achieve this task "Create an isolated network within this virtual datacenter"(for example VLAN based or vsphere port group-backed),NSX components are mandatory(edge gateway) and without NSX components we cannot do this ? Am i right?

Please suggest.

Yes and no. You can create a vSphere port group-backed Network Pool type:

This would not utilize the NSX overlay, however, by default, it will deploy an Edge for DHCP services. If you do not need DHCP services, this can be disabled and the Edge will be removed.

Hi Daniel,

I created a vSphere port group-backed Network Pool.

When i try to create a "Create an isolated network within this virtual datacenter" from customer Org.VDC Im getting below error.

Looks to be a licensing issue with NSX. Do you have the license attached to your hosts?

[ManivelR]

Hi Daniel,

Im using default license only.Apart from this,i was not configured any separate NSX license.

You need a regular NSX license - this license is inclusive of vSphere.

If you are within VCPP, this falls inside of the Advanced SP Bundle (7 point) functionality.

Thanks Daniel.I configured the correct NSX licenses.

When im trying to create isolated network within data center,im getting this error.It seems,we need to configure NSX edge "For deployment of NSX Edge appliance, cluster should be prepared and Ready/GREEN"

Thanks,

When you configure a static IP pool for this network, it wants to deploy an edge gateway that does DHCP on this isolated network. So you should only specify the network CIDR, name & description and let the other fields empty in the create dialog.

Thanks for your reply.It will be very helpful if  you please elaborate this, because still im facing some issues.

I came to know that,when we are trying to use vsphere-port group based,it will not use NSX overlay.

Steps followed:-

1) I created a network pool called "testone" with vsphere-port group based.Before that,I created a port group in vCenter under DVS(for that network pool).

2) When i was trying to create a new organization VDCs called "test2",i selected network pool as "testone".Post that, i was not selected anything like "Configure edge gateway" and then completed the new org.VDC wizard.

3) Logged in as test2 vis org.administrator.

4) When i was trying to "Create an isolated network within virtual data center" i have given network CIDR only(Left static pool as empty) but still Im getting the attached error(Error 2 screenshot).

Note:- I have configured NSX licenses only.Apart from that, i was not configured anything from NSX end(like host preparation etc..)

Thanks,
