SD-Access: Fabric Edge Nodes

The fabric edge node provides onboarding and mobility services for wired users and devices connected to the fabric.

It is a LISP tunnel router that provides the anycast gateway, endpoint authentication and assignment to overlay host pools along with group policy enforcement.

The fabric edge identifies and authenticates wired endpoints through 802.1x in order to place them in a host pool (VLAN SVI and VRF) and scalable group (SGT).

With authentication complete, it notifies the map server with the EID host address through the control plane node.

The fabric edge provides a Layer3 Anycast gateway for all connected endpoints and provides encapsulation plus decapsulation of host traffic to and from the endpoints.
