Abstract: Heterogeneous capabilities in an overlay fabric may be provided. First, it may be determined that a first link and a second link support a feature. Then the first link and the second link may be traversed with traffic between a host in a first Endpoint Group (EPG) connected to a first leaf switch and a second host in a second EPG connected to a second leaf switch when a topology preference for the feature is indicated for the traffic.

Abstract: In an embodiment, a method comprises: detecting a change in a multiple-switch configuration in a data communications network comprising a plurality of packet data switches configured as roots of multicast trees. In response to detecting that the multiple-switch configuration has changed, a first value, a second value and a third value representing limits on a number of multicast trees supported in the network and prioritization of the switches are retrieved. The method further comprises determining a type of the multiple-switch configuration change. In response to determining that the type indicates that a first switch was added to the multiple-switch configuration, using at least the first, second and third values, it is determined whether to configure the first switch as a first root in the multiple-switch configuration. The method is performed by one or more computing devices.

Abstract translation: 在一个实施例中，一种方法包括：检测包括配置为多播树根的多个分组数据交换机的数据通信网络中的多交换机配置的变化。 响应于检测到多交换机配置已经改变，检索表示在网络中支持的多个多播树的数量的限制的第一值，第二值和第三值，以及交换机的优先级。 该方法还包括确定多开关配置改变的类型。 响应于确定该类型指示第一交换机被添加到多交换机配置，至少使用第一，第二和第三值，确定是否将第一交换机配置为多交换机中的第一根 组态。 该方法由一个或多个计算设备执行。
