GENERIC_MST(G){T=NULL;WHILET未形成一棵生成树;do找到一条最小代价边(u,v)并且加入T后不会产生回路;T=T并上(u,v);} 1.普里姆(Prim)算法 prim算法的执行非常类似于寻找图中的最短路径的Dijkstra算法。假设N={V,E}是连通图,Et是N上最小生成树中边的集合。算法从Vt={u0}(u0属于V),Et={}开始,重...
对于RSTP（802.1W），思科采用per-vlan RSTP配置，简化了VLAN特定的RSTP配置。同样，MSTP（802.1S）允许基于VLAN实例的生成树配置，通过Switch(config)#spanning-tree mode mst命令启用MSTP模式，并通过Switch(config)#spanning-tree mst configuration命令进入MST配置模式。这些命令和特性旨在确保网络的稳定性...

我来回答你的追问，spanning-tree mode mst这个命令式启用多生成树协议的。你用的是普通的pvst思科私有的每vlan生成树，那个是自动启用的。而至于spanning-tree vlan 1 这些指令是用来调整pvst用的。所以指令是全的，只不过不支持mst罢了。你的路由器比较初级吧。功能不全很正常。如果是高端一点的肯定就...
spanning-tree mst 0-1,8 priority 4096 spanning-tree vlan 11,101-102,104,106 priority 4096 The switch doesn't have trunk set up with anything and the only vlan on switch is vlan 11; I think can replace all the config above with: spanning-tree vlan 11 priority 4096 Can you advise?
