2.9 Loop detection
2.9.1 Introduction
Loop detection can address the influence on network caused by a loop, providing the self-
detection, fault-tolerance, and robustness.
During loop detection, an interface enabled with loop detection periodically sends loop
detection packets (Hello packets). Under normal conditions, the edge interface should not
receive any loop detection packets because loop detection is applied to the edge interface.
However, if the edge interface receives a loop detection packet, it is believed that a loop
occurs on the network. There are two conditions that an edge interface receives a loop
detection packet: receiving a loop detection packet from itself or receiving a loop detection
