Hi All,
I am looking for evaluating VXLAN in our virtualized data center environment. The setup is as follows, multiple groups of VM are configured with each VM has its own network isolation in terms of both VLAN and IP network level. Groups of VM are part of three tier application model which one group VM would host end user application and remaining group of VM are hosting backend applications.
Below are the queries for VXLAN and need to know if the below deployment can be done:
1. We would like to deploy VXLAN for multiple VM to communicate with each other i.e. VM1 of VXLAN from VLAN 1 and IP address 10.10.10.0/24 to communicate with VM2 of VXLAN from VLAN 2 and IP Address 10.10.20.0/24. As long as I make VXLAN VNI to be same for both group of VM's (VM1 and VM2), this seems to be possible. But please clarify because I got confused because the inner VLAN ID of both VM's are different.
2. We also want VM configured for VXLAN to communicate with a router/firewall which is configured only for VLAN. The inner VLAN ID of VM and VLAN ID of router/firewall is the same. This is required as the clients connected to internet will connect to VM where end user application is hosted. I understand that for this I require VXLAN gateway (vCloud Networking and security/vShield edge). Could this be possible because I got confused with this post "http://communities.vmware.com/message/2154861#2154861" as I dont know for sure whether I am looking for comes under "L2 bridge functionlaity" or "L3-L7 gateway"?. If yes how the traffic flow happens in this case?
3. Considering I do not have VXLAN Gateway for time being (vCloud Networking and Security / vShield edge), then I want only VM to VM communication happening over VXLAN (as discussed in point 1) but VM to Router/Firewall communication to happen on native VLAN. i.e. VM with inner VLAN1 communicates with Router/Firewall with VLAN 1 without involving VXLAN gateway. Can this be done?
thanks in advance
