 # Cluster Inter-Connection with OVN-IC
 
 Kube-OVN supports interconnecting two Kubernetes cluster Pod networks via [OVN-IC](https://docs.ovn.org/en/latest/tutorials/ovn-interconnection.html),

+and the Pods in the two clusters can communicate directly via Pod IPs.
 Kube-OVN uses tunnels to encapsulate cross-cluster traffic, allowing container networks to interconnect between two clusters

 2. The subnet CIDRs within OpenStack and Kubernetes cannot overlap with each other in auto-interconnect mode.
    If there is overlap, you need to refer to the subsequent manual interconnection process, which can only connect non-overlapping Subnets.
 3. A set of machines needs to exist that can be accessed by each cluster over the network and used to deploy controllers that interconnect across clusters.

 2. 自动互联模式下不同集群的子网 CIDR 不能相互重叠，默认子网需在安装时配置为不重叠的网段。若存在重叠需参考后续手动互联过程，只能将不重叠网段打通。
 3. 需要存在一组机器可以被每个集群的 `kube-ovn-controller` 通过 IP 访问，用来部署跨集群互联的控制器。
 4. 每个集群需要有一组可以通过 IP 进行跨集群互访的机器作为之后的网关节点。
