| 发明名称 | System and method for managing topology changes in a network environment | ||
| 摘要 | A method is provided in one example embodiment and includes receiving a spanning tree protocol topology change notification (STP TCN) in a network; removing topology data for a first plurality of gateways associated with a first network segment ID that is shared by a particular gateway that communicated the STP TCN; and communicating an edge TCN to a second plurality of gateways associated with a second network segment ID and for which topology data has not been removed based on the STP TCN. | ||

| 主权项 | 1. A method, comprising: receiving a spanning tree protocol topology change notification (STP TCN) in a network; removing topology data using an STP for a first plurality of gateways associated with a first network segment ID that is shared by a particular gateway that communicated the STP TCN; and communicating an edge TCN over an intermediate system to intermediate system (IS-IS) protocol to a second plurality of gateways associated with a second network segment ID and for which topology data has not been removed based on the STP TCN; and removing topology data from the second plurality of gateways that was learned from a communicating network element that communicated the edge TCN without communicating the STP TCN into a second network associated with the second network segment ID. | ||
