BROCADE IP PRIMER

Chapter 9: Spanning Tree Protocol• Fast Port Span and Fast Uplink Span help speed up the interface convergenceprocess• Rapid Spanning Tree Protocol (RSTP), defined by IEEE 802.1w, speeds upinterface convergence to the sub-second level• Multiple Spanning Tree (MST), defined by IEEE 802.1s, provides a SpanningTree instance tied to a VLAN; this means that a trunk port betweenswitches could be forwarding for one VLAN, but blocking for a differentVLAN• Topology Groups provide one Spanning Tree instance to a group of VLANs• Virtual Switch Redundancy Protocol (VSRP) provides active/standbyredundancy for the Layer 2 infrastructureChapter Review Questions1.
