In this video, learn how to use SDA's overlay technique for creating connectivity on a modern LAN.
- [Instructor] The SDA overlay is a beautiful thing. … As an endpoint sends a frame to the first SDA node, … the node will encapsulate the frame … into a VXLAN tunnel and forward it to the next SDA node. … At this point, the SDA nodes will continue … to forward the frame based on its VXLAN tunnel information … until it hits the last SDA node, … which decapsulates it from its VXLAN wrapper … and delivers it to the endpoint destination. … All of this encapsulation and decapsulation … actually happens within the switches' ASICs, … so there's no performance penalty … since it's done in hardware. … The endpoint learning and forwarding process … goes as follows in an SDA network. … First, fabric edge nodes connecting the endpoint devices … learn endpoint IPs and MACs in the normal fashion, … and create a unique endpoint identifier or EID … for each endpoint. … As this EID is learned, it's then communicated … to a centralized database called the LISP map server. … The LISP map server maintains a list of the EIDs …
