    Rapid Spanning Tree 1 Rapid Spanning Tree Note: The Spanning Tree protocol and the Rapid Spanning Tree protocol are protocols for MAC bridges. They are described in the standards IEEE 802.1D-2004 and IEEE 802.1w. For this reason, the following description of these protocols usually employs the term bridge instead of switch.

  • Page 17: Rules For Creating The Tree Structure

    Rapid Spanning Tree 1.1 The Spanning Tree Protocol Port identification The port identification consists of two bytes. One part, the lower-value byte, reflects a fixed relationship to the physical port number. This part ensures that no port in a bridge receives the same designation as another port in the same bridge.
  • Page 18 Rapid Spanning Tree 1.1 The Spanning Tree Protocol Building the tree structure The bridge with the numerically smallest bridge identifier is made the root bridge. It forms the root of the tree structure. The structure of the tree depends upon the root path costs. The struc- ture that is chosen is the one that provides the lowest path costs bet- ween each individual bridge and the root bridge.

If the virtual router IP address is the same as the IP address of the router interface, then this router is the “owner”. If an owner exists, then VRRP assigns the owner the priority 255 and thus declares it the master.
