An industrial Internet of Things (IoT) deployment can potentially have thousands of devices. The need to perform, for example, a software upgrade on such devices presents a number of difficulties. While Bit Index Explicit Replication (BIER) offers a potential solution to some of those difficulties, with respect to low-cost IoT devices, utilizing BIER also presents various challenges. To address these challenges techniques are presented herein that facilitate the on-demand installation and uninstallation of a BIER state for the optimal replication of a multicast flow in support of, for example, software upgrades in an IoT domain, such as Routing Protocol for Low-Power and Lossy Networks (RPL) domain.
