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.
