Abstract: In an embodiment, a method of signaling status at a routing device is provided. In this method, the routing device establishes an inter-chassis control plane channel session with a remote routing device. Here, the routing device and the remote routing device are linked to a multi-homed routing device. The routing device then synchronizes with the remote routing device by way of the inter-chassis control plane channel session to identify a state of a link from the routing device to the multi-homed routing device. The state of the link is thereafter advertised by way of Border Gateway Protocol (BGP). Additionally, a method of discovering inter-chassis communication peers via BGP between the first and remote routing devices is provided.
Abstract translation: 在一个实施例中，提供了一种在路由设备处发信号通知状态的方法。 在该方法中，路由设备与远程路由设备建立机柜间控制平面信道会话。 这里，路由设备和远程路由设备链接到多宿主路由设备。 然后，路由设备通过机架间控制平面信道会话与远程路由设备同步，以识别从路由设备到多归属路由设备的链路的状态。 之后通过边界网关协议（BGP）通告链路的状态。 另外，提供了一种通过第一和远程路由设备之间的BGP发现机架间通信对等体的方法。
