What is the purpose of an edge node in an SD-Access network fabric?
Edge nodes identify and authenticate endpoints and register endpoint information with control plane nodes.
Edge nodes track endpoint IDs to location mappings, along with IPv4, IPv6, or MAC addresses.
Edge nodes are the gateway between the fabric domain and network outside of the fabric.
Edge nodes resolve lookup requests from edge and border nodes to locate destination endpoint IDs.
