How to recognise a Bidirectional Forwarding Detection (BFD) on Link Aggregation Group (LAG) interfaces by MAC address?
The Bidirectional Forwarding Detection (BFD) protocol defines a technique to detect faults in the bidirectional path between two forwarding engines. (interfaces, data links, etc.) It also provides a fast mechanism for detecting communication failures on any data links and the protocol can run over any media and at any protocol layer. Link Aggregation Group provides mechanisms to combine multiple physical links into a single logical link. This logical link provides a higher bandwidth and better resilience.
