用…MSTP多生成树协议
通过创建多个VLAN实例将原有的STP、RSTP升级避免单一VLAN阻塞后导致带宽的浪费通过将VLAN数据与实例绑定有效提升网络速率。
VRRP虚拟路由冗余协议
用于提供冗余的网关功能确保网络中的设备能够自动切换到备用网关从而实现网络的高可用性。 如上图所示为内网三层网络架构最上层两台核心交换机实现负载均衡和冗余作用保证网络的稳定和安全运行。
配置MSTP(VLAN 10 20主根桥在核心交换机1VLAN 30 40主根桥在核心交换机2)
①所有交换机配置MSTP实例instance,vlan 10 20 属于instance 1vlan 30 40 属于instance 2并激活配置
②核心交换机1配置instance 0,1 的主根桥instance 2的次根桥(instance 0为默认实例如vlan 1)
③核心交换机2配置instance2 的主根桥instance 0,1的次根桥(instance 0为默认实例如vlan 1)
配置VRRP(核心交换机1为VLAN 10 20的主网关核心交换机2为VLAN 30 40 的主网关)
①在核心交换机1和核心交换机2配置VLAN 10 、VLAN 20、VLAN 30、VLAN 40接口的虚拟网关地址为10.100.*.1
②在核心交换机1的VLAN 10 、VLAN 20、VLAN 30、VLAN 40接口配置地址为10.100.*.2,并配置在VLAN 10 和 VLAN 20 的优先级priority 为120,即抢占为Master
②在核心交换机2的VLAN 10 、VLAN 20、VLAN 30、VLAN 40接口配置地址为10.100.*.3并配置在VLAN 10 和 VLAN 20 的优先级priority 为120,即即抢占为Master

在核心交换机1上输入命令display stp brief
在instance 1 中所有接口为DESI(指定端口)即核心交换机在instance 1 上为主根桥 在核心交换机2上输入命令display stp brief
在instance 2 中所有接口为DESI(指定端口)即核心交换机在instance 2 上为主根桥 验证VRRP
在核心交换机1上输入命令display vrrp brief
vlanif 10 和vlanif 20接口的状态为Master 在核心交换机2上输入命令display vrrp brief
vlanif 30 和vlanif 40接口的状态为Master 终端PC上验证ipconfig /renew 测试交换机的主备切换
关闭核心交换机1 查看核心交换机2的STP和VRRP状态
核心交换机2的instance 1 和 instance 2 都为主根桥即所有接口都为DESI指定端口 核心交换机2所有vlanif接口的VRRP状态都为Master 测试二打开已经关闭的核心交换机1 查看核心交换机的STP状态
核心交换机1在instance 1 上又成为主根桥核心交换机2在instance 2还是主根桥 查看核心交换机的VRRP状态
核心交换机1抢占到vlanif 10 和vlanif 20接口的状态为Master
核心交换机2的vlanif 30 和vlanif40接口的状态保持为Master 总结
①MSTP不像STP和RSTP那样会直接将接口阻塞掉来防止环路而是将包含VLAN的实例关联的接口进行阻塞这样能最大化的利用所有线路的带宽从而提升网络性能。
②配置VRRP中可以将多个网关平均分配给两台核心设备这样既实现了负载均衡又实现了链路冗余。
