    Abstract: In one embodiment, an authoritative edge device (AED)-server in a computer network maintains assignment of an active AED for a particular virtual local area network (VLAN), and in response to a triggered re-assignment, sends an AED change request identifying an old active AED for the particular VLAN and a new active AED for the particular VLAN (e.g., and/or corresponding backups). In response to receiving the change request, the old active AED ceases forwarding of traffic for the particular VLAN and transmits a relinquishment confirmation into the network. Also, in response to receiving the change request and the relinquishment confirmation from the old active AED, the new active AED assumes responsibility for traffic forwarding for the particular VLAN and transmits an activation confirmation into the network. The change request is then deemed completed by the AED-sever upon receipt of both the relinquishment confirmation and the activation confirmation.

    Abstract: A system and method for fast roaming in one or more enterprise fabric network. The fast roaming involves correlation operations performed in one or more databases managed by control plane of the fabric network to update routing locator entries associated with L2-VNID and L3-VNID in one or more databases when a client moves from behind a first switch to behind a second switch. In some embodiments, the control plane finds the L3-VNID from the L2-VNID. The L3-VNID is used to search for all IP addresses corresponding to a client-MAC. At least new routing locator value that is used in the routing locator entries is provided to the first switch, the second switch, and border nodes associated with the fabric network.

    Abstract: Techniques are provided for designating, in an overlay transport virtualization (OTV) network connected to a data center, an edge device to act as a backup authoritative edge device (BAED) for an authoritative edge device (AED) for multicast packet encapsulation and forwarding. Data traffic associated with a given virtual local area network (VLAN) may be detected from a multicast source in the data center addressed to recipients in a site group. A mapping may be generated between the site group and a core data group in the OTV network for traffic from the multicast source. Advertisements may be sent of the mapping to edge devices in another data center across the OTV network. A similar configuration is presented for a BAED for inbound multicast traffic to a data center.
