Abstract
A network reachability verification method and apparatus, and a computer storage medium are provided, and pertain to the field of network technologies. The method includes: obtaining a source interface and a destination interface that correspond to a virtual packet in a target network; and verifying reachability of the virtual packet in an overlay network based on a logical topology of a plurality of forwarding instances of a plurality of network devices in the target network, routing information of the plurality of forwarding instances, a source forwarding instance corresponding to the source interface, and a destination forwarding instance corresponding to the destination interface. In this way, single-layer reachability verification on the overlay network in the target network is implemented, and verification accuracy is high.
