Abstract
This application discloses a forwarding entry monitoring method and apparatus, to quickly determine a changed forwarding entry, thereby improving locating efficiency. The method includes: determining, by a first node, a monitored data stream; determining, by the first node, that a stored forwarding entry changes, where the forwarding entry is used to forward the data stream; and sending, by the first node, a first packet to a second node. The second node is located on a transmission path of the data stream, and the second node is a previous-hop node of the first node. The first packet carries a change instruction.
