Abstract: Techniques and architecture are described for L2 service insertion in a network. More particularly, the techniques and architecture provide for monitoring a L2 service, e.g., firewall, MAC address (instead of learning the MAC address) and registering/de-registering the service node (e.g., fabric border or edge or LISP service_etr) to the service control plane (e.g., LISP MSMR) based on this. This not only load-balances the traffic (per L2 flow) but also tracks it for node's liveliness. The techniques and architecture also provide L2 service insertion connected to a service border to allow for dynamic SGT based service, e.g., firewall, insertion for both software defined access (SDA) fabric and non-fabric deployments.

Abstract: Techniques for identifying locations of network devices in a fabric network. The method includes a network controller and/or control plane of a network fabric coupled to an access switch at a software-defined access (SDA) site. At least one mapping is registered at the SDA site and sent with the location data from the access switch to the network controller. The network controller and/or control plane is configured to at least one of to learn, update, and publish location data of a destination address from at least one mapping received from the access switch by the location data being associated with a mapping at the SDA site and destination address. The network controller identifies the location of the destination address from a received request based on associating the destination address with the location learned from the location data of at least one mapping that has been registered at the SDA site.
