rstplip.1.1.02

  802.1d spanning tree (STP) standard designs, and believe that it could resume in about 1 minute after the failure, this kind of performance is adequate. Into the LAN environment as the third Exchange, bridges began to compete with routing solution, the latter open shortest path routing protocols (OSPF) and enhanced Interior Gateway Routing Protocol (EIGRP) can provide alternate paths in a shorter time. Cisco introduces Uplink Fast and Backbone Fast and Port Fast feature to enhance the original 802.1D standards to reduce the bridge network convergence time, but lack of these mechanisms is that they are private and require additional configuration. Rapid Spanning Tree Protocol (RSTP;IEEE802.1w) can be seen as 802.1D rather than revolution. 802.1D terms remained essentially the same, most of the parameters have not changed, so users familiar with 802.1D can quickly configure a new Protocol. In most cases, without any configure RSTP is superior to Cisco's proprietary extensions. 802
