Spanning tree also allows a network design to include backup links providing fault tolerance if an active link fails. The highest bit is the topology change acknowledge (tca) flag. Bridge id—id of the regional root for the ist or an msti. A switch sends bpdus using a unique source mac address from its origin port to a multicast address with destination mac (01:80:c2:00:00:00, or 01:00:0c:cc:cc:cd for cisco proprietary per vlan spanning tree).
