More spanning tree (MST) outlined More spanning tree (MST) outlined (Please specify the source of Jahweh technology http://www.ccxx.net reproduced) More spanning tree (MST) IEEE802.1w Rapid Spanning Tree (RST) algorithm can be extended to multiple spanning tree, virtual local area network (VLANs), load balancing environment and the rapid convergence of the functions and ;MST converges faster than PVST+ and 802.1D, Spanning Tree and 802.1w PVST+ structure compatible. Multi-spanning tree (MST), through corridors (trunks) to create a number of spanning tree, the tree association VLANs related to the process, the process is independent of each other spanning tree topology ;MST process of transmitting data for a number of paths and load balancing. increase the network capacity because of a fault-tolerant process (transponders Path), the fault will not affect other processes (transponders Path). In large networks of different networks, and through different VLANs and Spanning Tree MST positioning process to be easier to manage the distribution and use of redundant network paths; A tree with the same process can only exist in the distribution process VLAN bridges, we must use the same configuration information to a group of bridge configuration MST, This enables the Spanning Tree Bridge are able to participate in a group process, the MST has the same allocation of the interconnection of the bridge constitutes more information spanning tree (MST) region. 　　 More spanning tree (MST) that the use of the Rapid Spanning Tree (RSTP) agreement-called multi-Spanning Tree Protocol (MSTP), the MST has the following characteristics : ． MST operation of a tree called the constant internal spanning tree (IST), IST MST with the overall increase of the internal information tree information ;MST zones adjacent single spanning tree (SST) and the MST area as a separate bridge. ． MST operation of bridges and a single spanning tree bridge interoperability : * MST internal operation of the bridge spanning tree (IST), IST MST with the overall increase of the internal information tree information. * Internal Spanning Tree (IST) link of all is the overall situation and the bridge spanning tree MST (CST), a sub-tree, the overall Spanning Tree (CST) contains the entire area of the bridge, MST zones adjacent single spanning tree (SST) Bridge and the MST area as a virtual bridge. * Overall and internal spanning tree (CIST) is the internal tree each MST (IST), the overall interconnection MST single spanning tree bridge spanning tree and a pool, and an MST region is the same as the one IST, and an MST outside the same ;STP CST, RSTP and MSTP jointly build a bridge to do for the general and a separate internal spanning tree (CIST) roots. ． MST each additional tree establishment and maintenance of the district, which is MST process spanning tree (MSTIS) vs. No. 0 in the process, the process MSTIS No. 1, 2, 3, etc.; Even MST areas are connected, in any 028A MST local area and are also independent of the other MSTI; MST MST processes and IST in the border areas pose a combination CST : * 028A of the Spanning Tree MSTP information contained in the records (M-record), the MST M-record always encapsulated in the BPDUS, MSTP calculated from the original tree is called M-tree (M-tree), M MST active only in the tree. M trees and IST border merger in the form CST MST -- VLAN PVST+ BPDU to generate CST, MST provide interoperability and PVST+ ． MST PVST+ support the expansion : * UplinkFast and BackboneFast MST in the way invalid, but they were included in RSTP * Support PortFast * BPDUFilter MST and the way in support BPDUGuard * LoopGuard MST and the way in support RootGuard * For private VLANs (Pvlan) from the main VLANs VLANs must be mapped into a tree and the process (Please specify the source of Jahweh technology http://www.ccxx.net reproduced) [ Closed window ]
