摘要
In one embodiment, an apparatus includes a physical port and a plurality of logical sub-interfaces under the physical port. The physical port and the logical sub-interfaces are configured as a Bidirectional Forwarding Detection (BFD) neighbor group. The physical port being configured to run BFD sessions to detect failures at a first rate that is substantially faster as compared to a second rate of BFD sessions to detect failures on the logical sub-interfaces. The physical port notifies the logical sub-interfaces of a BFD failure at the physical port, with the logical sub-interfaces shutting down responsive to the notification.
