  • Patent number: 9584421
    Abstract: Embodiments herein achieve proxy FHRP for anycast routing services through the coordination of L2MP edge switches to allow load balancing for the use of routing services. Such embodiments may avoid duplicity and coordinate control planes between the edge switches to present a proxy interface to the rest of the network for the routing services. As such, multipathing and load-balancing for efficient use of crucial services may be provided for client nodes inside the network.

  • Patent number: 9178837
    Abstract: An example method is provided and includes receiving a data message from a first virtual local area network; determining at an edge switch-router of a Layer-2 network whether the message should be routed; and routing the message in the Layer-2 network at the edge switch-router if the message should be routed. The method also includes switching the message at the edge switch-router if the message should not be routed.

  • Patent number: 8873551
    Abstract: Techniques are described which facilitate multi-destination forwarding in a Layer 2 Multipath (L2MP) network which includes an emulated switch. The emulated switch may correspond to two or more underlying peer link switches in the L2MP network, in which each of the peer link switches is linked to a Classical Ethernet (CE) switch over a virtual port channel (vPC). Traffic received by one of the peer link switches over the vPC is automatically forwarded to the other peer link switch (or switches). Multi-destination frames originating from the L2MP network addressed to hosts within the CE network are sent over only one of the peer link switches.

  • Patent number: 8724517
    Abstract: A method is provided that includes configuring a first network element as a peer to a second network element. The first network element and the second network element are configured to execute a spanning-tree protocol (STP) in a network environment. The method may also include configuring a priority characteristic to be a same value for the first network element and the second network element such that both operate as root network elements for other network elements in the network environment.

  • Patent number: 8509087
    Abstract: In one embodiment, a method includes assigning at a switch in a layer 2 multipath network, costs to a link in the network, each of the link costs associated with a different graph for forwarding traffic in the network, transmitting the link costs to other switches in the layer 2 multipath network, and receiving and forwarding traffic according to one of the graphs. An apparatus is also disclosed.

  • Publication number: 20130155846
    Abstract: An active-standby virtual port channel mechanism may be provided, where at any point only one virtual port channel link would be active. Upon failover of the active, a fast failover mechanism is employed to move active traffic to a standby port channel link.
