Abstract

A communications connection detection method includes sending, by a first network node, a detection request packet to a second network node, where the detection request packet is used to detect whether the first network node and the second network node are in a connected mode, deleting, by the first network node, a next hop resolution protocol (NHRP) table between the first network node and the second network node when the first network node determines that the first network node does not receive a detection response packet sent by the second network node.
