Hi all, Till now, it seems that too much attention has been paid to the use of L2VPN for data center interconnect. Although there are still a few clustering applications which rely on non-IP or non-routable IP communications (e.g., heartbeat messages between cluster nodes), more and more cluster vendors are offering clustering applications based on Layer 3 interconnection. In addition, geographical high-availability clusters is not a must in many data center interconnect cases.
As L3VPN has many distinct advantages over L2VPN for data center interconnect such as: scaling forwarding tables of data center switches, path optimization, unknown unicast and ARP suppression... why not try to use the proven L3VPN technology for data center interconnect in the scenario where the limitations as mentioned above don't exist?
