摘要： A method is provided in one example embodiment and includes establishing a virtual trunk link (trunkl - trunkn) between a first network element (extGWl - extGWn) and a second network element (intGWl - intGWn). The first and second network elements are located in gateway element ISGW2 at a first site (site2), and the first site and a second site comprise at least a portion of an overlay network (SEGMENT 10010, SEGMENT 10020). The method further includes receiving data traffic at the first network element, which data traffic is associated with a segment of the overlay network, and mapping a first network identifier (SEGMENT 10010) allocated to the overlay network segment at the first network element to a virtual trunk link (trunkl- trunkn) and a VLAN ID. The method additionally includes forwarding the data traffic from the first network element to the second network element via the virtual trunk link with the VLAN ID. Preferably, two types of VXLAN gateways are thus connected, or paired, through virtual trunk links to facilitate VXLAN extension across multiple sites. In gateway element ISGW2, multiple VXLAN gateway virtual machines are deployed in pairs. They are categorized into two types, internal and external gateways. Internal VXLAN gateways connect to VXLAN tunnel endpoints (VTEPs) within the site and may run control protocols such as BGP or use internal Virtual Supervisor Module (VSM) to Virtual Ethernet Module (VEM) communication mechanism for VTEP and segment discovery within a site or for that matter multicast within that site. In contrast, external VXLAN gateways connect to gateways of other sites. The allocation of VLAN 20 to support segment ID mapping is a matter internal to to gateway element ISGW2. Scalable and stable multi-site connectivity can thus be provided.
摘要翻译：在一个示例实施例中提供了一种方法，并且包括在第一网络元件（extGW1-extGWn）和第二网络元件（intGW1-intGWn）之间建立虚拟中继线链路（trunk1-trunkn）。第一和第二网络元件位于第一站点（站点2）处的网关元件ISGW2中，并且第一站点和第二站点包括覆盖网络的至少一部分（SEGMENT 10010，SEGMENT 10020）。该方法还包括在第一网络单元处接收数据业务，哪个数据业务与覆盖网络的一个段相关联，以及将分配给第一网元的覆盖网段的第一网络标识符（SEGMENT 10010）映射到虚拟中继链路（trunkl-trunkn）和VLAN ID。该方法还包括经由具有VLAN ID的虚拟中继链路将数据业务从第一网元转发到第二网元。优选地，两种类型的VXLAN网关因此通过虚拟中继链路连接或配对，以便于跨多个站点的VXLAN扩展。在网关元素ISGW2中，多个VXLAN网关虚拟机成对部署。它们分为两种类型，内部和外部网关。内部VXLAN网关连接到站点内的VXLAN隧道端点（VTEP），并可以运行诸如BGP之类的控制协议，或者使用虚拟以太网模块（VEM）的虚拟以太网模块（VEM）通信机制进行控制协议，VTEP和站点内的段发现这是在该网站内的多播。相比之下，外部VXLAN网关连接到其他站点的网关。 VLAN 20的分配支持段ID映射是网关ISGW2内部的一个问题。因此可以提供可扩展和稳定的多站点连接。

摘要： One embodiment includes, inter alia , methods, apparatus, computer-storage media, mechanisms, and/or means associated with automated transitioning between different communication protocols in a network. In one embodiment, automatic transition routers are automatically discovered along with the knowledge of what non-native protocols need to be transported across a network. Communication pathways are automatically established as needed to transport these non-native protocols. One embodiment is particularly useful in transitioning a network from one protocol to another, such as from Internet Protocol version 4 to version 6.
