Hi, Kural, About the IPV6 SFC, the following is my debug process. Now, the func CalculateRoutes() can genarate the create route to the pod, but can’t add to the corresponding pod. The calculated result for the sfc-head pod: But for the agent pod, while adding routes to the container through func ContainerAddRoute() failed. Because in this function, it will get the host network configuration to find the default gateway, to add an extra route to the host network through the default gateway on the host.

Docker CNM What is CNI? How CNI plugin works? What a CNI plugin is made of? How a CNI plugin is being used in K8s? How a CNI plugin is executed? Anatomy of Pod networking What is CNI CNI stands for Container Networking Interface An interface between container runtime and the network implementation Configure the network interfaces and routes Concern itself only with the netwrok connectivity. How CNI plugin works? A CNI binary Handle connectivity - configures the network interface of the Pod /opt/cni/bin A daemon Handle reachability - manager routings across the cluster What a CNI plugin is made of ?

OVN Open virtual Network

Open Virtual Network OVN(Open Virtual Network) is a series of daemons for the Open vSwitch that translate virtual network configuration into OpenFlow. OVN provides a higher-layer of abstraction than Open vSwitch, working with logical routers and logical switches, rather than flows. Why did we choose OVN for Nodus? One of the best programmable controller Hides OVS complexity Broader eco-system L2 CNI - Support for unicast, multicast, broadcast applications One site level IPAM - No IP address restriction with number of nodes
