Abstract:
In one embodiment, a first routing device establishes a virtual channel with a remote routing device in a G.8032 protocol Ethernet network ring. The first routing device and the remote routing device each being linked to a multi-homed routing device having Layer 2 connectivity to a core network. The multi-homed routing device is not configured with the G.8032 protocol. The first routing device identifies a link state from the first routing device to the multi-homed routing device. Layer 2 connectivity of the first routing device to the core network is controlled based upon the identified link state of the first routing device.
