Abstract
A computer network device (such as a switch or a router) that prevents loop occurrence is described. During operation, the computer network device communicates, via one or more ports, data packets with a corresponding one or more second ports in a second computer network device, where a given data packet includes a source address and a destination address, and where the one or more ports and the second one or more ports specify a link between the computer network device and the second computer network device. Moreover, when the link goes down and then comes back up, the computer network device may block forwarding, via the one or more ports, of additional data packets based at least in part on a predefined delay.
