Abstract: Embodiments generally relate to enabling encapsulation in networks. In one embodiment, a method includes receiving a message from an edge configuration device, wherein the message contains shortest path bridging (SPB) configuration information. The method also includes performing provider backbone bridge (MAC-in-MAC) encapsulation in response to receiving the message.

Abstract: A method, apparatus and computer program product for providing multi-homing techniques for SPB networks is presented. A set of UNI nodes that receive multicast packets are determined based on Backbone Media Access Control-Destination Address (BMAC-DA)/I-Tag Service Identifier (I-SID) of received multicast packets for multicast packets within a transport network. A separate Egress Port Mask is determined for each Backbone-Virtual Local Area Network (B-VLAN) of the transport network, wherein the Egress Port Mask is determined such that only one UNI node of the set of UNI nodes forwards said multicast packets. A set of UNI copies of said multicast packets are filtered out by applying the Egress Port Mask, wherein copies that are not in the Egress Port Mask are dropped. Copies of multicast packets that are not dropped are sent out.

Abstract: A method, apparatus and computer program product for providing Virtual Routing and Forwarding (VRF) and gateway Media Access Controller (MAC) distribution is presented. At least one subnet associated with a Layer 2 Virtual Switching Network (L2VSN) is provided on a network device. A message is propagated to a distributed Datapath. Network devices install the message as a routable MAC address on the L2VSN for the Layer 3 Virtual Switching Network/Virtual Routing and Forwarding (L3VSN/VRF) associated with the message. Edge devices route packets on the L2VSN addressed to the gateway MAC address.

Abstract: A VLAN is implemented with a logical hub and spoke topology that obviates local switching. Member devices are connected to a hub device such as a router via intermediate devices such as Layer 2 switches that support individual IP subnets within the VLAN. The Layer 2 switch does not allow bridging, so there is no IP subnet broadcast domain. Further, the Layer 2 switch implements only a single logical broadcast uplink port which is connected to the router. The Layer 2 switch also implements only point-to-point downlink ports, i.e., to individual member devices. Consequently, all traffic is forced to flow through the router, e.g., broadcast traffic, multicast traffic and traffic of unknown destination received by the Layer 2 switch from a member device is only flooded to the router, and the router performs intra-subnet routing in addition to routing between subnets and between VLANs.

Abstract: Methods, systems and computer readable media for discovering edge devices within a network and establishing connectivity between the edge devices and one or more corresponding network services are described. In some implementations, the method can include snooping a received packet to determine whether a source entity of the received packet is known and to determine whether the received packet can be handled by a first processing layer based on a rule set in the first processing layer and configured to be accessed by the first processing layer. The method can also include classifying the packet at the first processing layer when the packet can be handled by the first processing layer, and forwarding the packet to a second processing layer when the packet cannot be handled by the first processing layer.

Abstract: A VRRP router group can operate in either a standard VRRP mode or a distributed gateway mode in which all VRRP routers generate VRRP control packets but transmit those packets only to local access network-side hosts. The rate of VRRP control packet generation may be decreased in the distributed gateway mode relative to the standard mode. Moreover, VRRP router CPUs may cease processing of VRRP control packets in the distributed gateway mode.

Abstract: A method, apparatus and computer program product for performing optimized distributed routing for stretched data center models through updating route advertisements based on changes to Address Resolution Protocol (ARP) Tables is presented. Port members of an Internet Protocol I (IP) interface or Virtual Local Area Network (VLAN) are distinguished into Access Interfaces which only lead to hosts on said subnet and Trunk Interfaces which lead to other redundant routers on said subnet. In the subnet of a network a network route for the subnet is always advertised. A separate host route corresponding to an Internet Protocol (IP) address of each Address Resolution Protocol (ARP) table record that points to an Access Interface is advertised and route advertisements are changed for a host in said subnet for tracked access interfaces.

Abstract: Embodiments generally relate to message transmission in networks. In one embodiment, a method includes enabling a user to provide shortest path bridging (SPB) configuration information. The method also includes receiving the SPB configuration information from the user. The method also includes sending the SPB configuration information to an edge server device.

Abstract: IP Multinetting on a local area network is simulated by performing VLAN translation at a port connecting to the local area network. This allows IP addresses from multiple subnets to be associated with a single VLAN on the Local Area Network (LAN), while allowing the core switch to process the packets with a one-to-one correspondence between IP Subnet and VLAN. When a packet is received from the local area network at an IP multinetting port, the VLAN ID will be read to determine if the packet contains the IP Multinetting VLAN ID. The IP Subnet address will also be checked to see if the packet is associated with an IP Subnet that is part of the Multinetting. If so, the multinetting VLAN ID will be changed to an IP Subnet specific VLAN ID before the packet is processed by the core switch.
