    摘要: 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.

    摘要: An example method is provided and includes a multicast data message from a data source, the message in a first virtual local area network and being associated with a multicast group. The method also includes calculating a hash value based on the virtual local area network, the data source, and the multicast group, determining a port for a designated router in a Layer-2 network based on the hash value, and switching the multicast data message to the port that was determined.

    摘要: In one embodiment, a method includes building an address resolution cache for a layer-3 router in a first layer-2 datacenter, where the address resolution cache includes a plurality of entries, each of the entries containing a host network address, a host hardware address, and a switch identifier for a switch serving a host, intercepting an address resolution flood within the first layer-2 datacenter that seeks address resolution for a host in a second layer-2 datacenter, and generating a response to the address resolution flood that indicates a source in the second layer-2 datacenter, where data indicating the source in the second layer-2 datacenter is accessed from the address resolution cache.

    摘要: A first switch of a first network may receive a second set of information including routing identifiers associated with a second network, wherein the first switch of the first network is connected to a second switch of the second network. The first switch of the first network may transmit a first set of information 54 including routing identifiers associated with the first network. The first switch may determine whether a conflict exists between the second set of information and the first set of information. A conflicting one of the routing identifiers associated with the first or second network may be transitioned to a non-conflicting routing identifier according to the determination of whether a conflict exists between the first set of information and the second set of information.

    摘要: Methods and apparatus for merging two or more networks are disclosed. In one embodiment, a first switch of a first network receives a second set of information including routing identifiers associated with a second network, wherein the first switch of the first network is connected to a second switch of the second network. The first switch of the first network transmits a first set of information including routing identifiers associated with the first network. The first switch determines whether a conflict exists between the second set of information and the first set of information. A conflicting one of the routing identifiers associated with the first or second network may be transitioned to a non-conflicting routing identifier according to the determination of whether a conflict exists between the first set of information and the second set of information, thereby enabling data to flow between the first network and the second network via a link between the first switch and the second switch.

    摘要: A solution is provided wherein the interfaces between multiple chassis (e.g., edge switches) in a network of layer 2 devices and a spanning tree device are treated as a single emulated switch. This emulated switch effectively enables two different views to the two different sides. Thus, frames from the network of layer 2 switches destined to any port of the emulated switch may take any of the links (through any of the physical switches), thereby enabling effective load-balancing for frames traveling from the layer 2 network side into the spanning tree device. Meanwhile the spanning tree device does not recognize an illegal loop in its connection to two different edge switches as it views the two links as a single logical EtherChannel.

    摘要: In one embodiment, a first switch is located at a first border between first networks that utilize a STP to detect and break loops and second networks. The first switch is interconnected via the first networks with a second switch located at a second border between the first networks and the second networks. The first switch detects, via a protocol other than STP, addition of a link in the second networks that provides a new path across the second networks between the first switch and the second switch. The first switch blocks data packets from traversing through one or more network boundary ports of the first switch coupled to the first networks, while allowing STP BPDUs to traverse through the one or more network boundary ports, for a period of time sufficient for the first networks to discover the new path using STP.
