The share-link protection function on a device helps automatically transition to the Rapid Spanning Tree Protocol (RSTP) working mode. It can also be used together with root protection to avoid network loops.
Share-link protection is used in the scenario where a device is dual homed to a network.
When a share link fails, share-link protection forcibly changes the working mode of a local device to RSTP. This function can also be used together with root protection to avoid network loops.
