With the continued evolution of technology, and the amalgamation of routing and switching capabilities on the same physical platform, it soon became apparent that switched network convergence lagged behind that of routing protocols such as OSPF and EIGRP, which are able to provide an alternate path in less time. The 802.1W standard was designed to address this.
The IEEE 802.1W standard, or Rapid Spanning Tree Protocol (RSTP), significantly reduces the time taken for STP to converge when a link failure occurs. With RSTP, network failover to an alternate path or link can occur in a subsecond timeframe. RSTP . . .
