Explanation

In the Cisco SD-Access fabric, Edge Nodes are the switches to which endpoints (users, devices) connect, and they perform two key roles: (A) Act as anycast Layer 3 gateway - Edge Nodes host the default gateway for all endpoint subnets using a common anycast MAC and IP address. Because every edge node in the fabric shares the same gateway address, endpoints can move between edge nodes without changing their default gateway. (C) Map users to virtual network - Edge Nodes classify incoming endpoint traffic into the appropriate Virtual Network (VN) and Scalable Group Tag (SGT) based on authentication results from ISE, applying the correct macro- and micro-segmentation policy. Border Nodes (not Edge Nodes) handle EID subnet advertisement to external networks (B) and act as LISP proxy tunnel routers for external prefixes (D). Routing and transporting IP traffic (E) is a general fabric function distributed across all fabric nodes.
