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 translation: VRRP路由器组可以在标准VRRP模式或分布式网关模式下运行，其中所有VRRP路由器都生成VRRP控制报文，但只将这些报文发送到本地接入网侧主机。 在分布式网关模式下，相对于标准模式，VRRP控制包生成速率可能会降低。 此外，VRRP路由器CPU可能会在分布式网关模式下停止处理VRRP控制数据包。

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 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 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: 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.
