Abstract: The embodiments herein push notifications to network devices used by a shared service to which a roaming host in a network fabric is subscribed. For example, a network fabric controller can access a VN policy table which stores the relationships between the virtual networks in the network fabric. Using this table, the controller can identify what shared service VNs (i.e., extranets) can communicate with the host's VN. The controller can push out notifications to the network devices used by the shared service VNs to store the new location of the host. That is, the network devices that locally store a location of the host can update their routing caches to point to the new location of the host. In this manner, the network fabric can reduce the time needed to reconverge on the new location of the host by updating the network devices used by the shared service VNs.

Abstract: In embodiments disclosed herein involve receiving a first packet, where the first packet originated from a first device on a first virtual local area network (VLAN) in a first plurality of VLANs, where routing is enabled among each of the first plurality of VLANs. A first temporary value is assigned to a first VLAN identifier associated with the first packet, where the first temporary value corresponds to the first plurality of VLANs. Additionally, the first packet is processed based on a plurality of flow tables. Further, a first destination value is assigned to the first VLAN identifier, where the first destination value corresponds to a second VLAN in the first plurality of VLANs, and the first packet is transmitted to a second device on the second VLAN.

Abstract: In one embodiment a network device includes a plurality of ports. The network device is adapted to receive at least one configuring instruction, and adapted, after receipt of any of the at least one configuring instruction, to configure one or more access ports, of the plurality of ports, for endpoint virtual local area network (VLAN) assignment that is in accordance with at least one VLAN assignment algorithm. The at least one VLAN assignment algorithm allows at least two endpoints to be assigned to at least two different respective VLANs of a plurality of VLANs in a network, the at least one VLAN assignment algorithm enabling the at least two endpoints to connect to a same access port of the one or more access ports and provide data which is not VLAN tagged when received at the same access port.
