摘要： Example embodiments are directed to methods of configuring a virtual private local area network service for an enterprise. At least one method includes assigning a virtual private local area network instance to a first node within a network. A first node attempts to establish a label distribution protocol session between the first node and at least one other node within the network based on an interior gateway protocol map. The interior gateway protocol map identifies the at least one other node and nodes connected to the at least one other node. The virtual private local area network service is established based on the label distribution protocol sessions that are established.

摘要： A method comprises an operation for facilitating authentication of a client device attempting to connect to a port of a network element. Facilitating authentication includes determining whether the client device is configured for being authenticated using a first authentication mechanism and, in response to determining that the client device is not configured for being authenticated using the first authentication mechanism, determining whether the client device is configured for being authenticated using at least one other authentication mechanism. For each one of the authentication mechanisms, an operation is provided for providing the client device with network connectivity dependent upon a respective first classification policy structure in response to the client device being successfully authenticated and an operation is provided for providing the client device with network connectivity dependent upon a respective second classification policy structure different that the first classification policy structure in response to the client device failing to be successfully authenticated.

摘要： Customer virtual local area networks (C-VLANs) connecting multiple LAN segments are set up through a provider network (12). Provider edge bridges (PEs) are coupled to customer edge bridges (CEs) to provide a transparent link between LAN segments. To determine whether a backdoor link is used in the C-VLAN topology, PEs monitor MAC address from a predetermined time after a TCN is received to determine if there are contradictory addresses or new addresses relative to the existing MAC address tables (or forwarding databases) that are indicative of a backdoor link. If so, an unlearning message is sent to bridges in the provider domain. In another embodiment, CEs set a snoop bit to indicate which TCNs must be snooped.

摘要： An exemplary method directs client devices client devices in a computing network to a remediation node. A subset of the client devices to receives remediation services is identified with a single common label. Upon determining that one of the client devices originating a communication request packet is identified by the single common label, processing the communication request packet by routing the communication request packet to a redirection server, and transmitting from the redirection server to the one client device a hypertext transfer protocol (HTTP) command specifying that the one client device redirect communications to the remediation node so that remediation services can be supplied to the one client device via the remediation node.
