Abstract: A method, apparatus and computer program product for providing synchronization of a multi-chassis cluster using SPB I-SID trees is presented. A plurality of network devices are defined for making up a single cluster. Each network device of the cluster is configured with a same cluster Identifier (cluster ID) and each network device of the cluster signals an Service Instance Identifier (I-SID). At least one ISID multicast tree is generated, each one of the at least one multicast tree rooted at one node of the cluster. Cluster synchronization messages are exchanged between the network devices of the cluster using the at least one multicast tree.
