eNSP——MSTP+VRRP

ps：虽然这个实验看起来很复杂，实际上配置很简单，就是有点繁琐 ：）

MSTP+VRRP综合实验

S1配置

基础配置

[S1]int g0/0/1
[S1-GigabitEthernet0/0/1]p l t
[S1-GigabitEthernet0/0/1]p t a v 10 20
[S1-GigabitEthernet0/0/1]int g0/0/2
[S1-GigabitEthernet0/0/2]p l t
[S1-GigabitEthernet0/0/2]p t a v 10 20
[S1-GigabitEthernet0/0/2]int g0/0/3
[S1-GigabitEthernet0/0/3]p l t
[S1-GigabitEthernet0/0/3]p t a v 10 20

?mstp配置

[S1]stp mode mstp    //配置stp模式	
[S1]stp region-configuration         //进入mstp配置视图
[S1-mst-region]region-name huawei
[S1-mst-region]revision-level 12    //设置修正等级
[S1-mst-region]instance 10 vlan 10        //配置实例映射
[S1-mst-region]instance 20 vlan 20
[S1-mst-region]active region-configuration     //使配置生效
[S1]stp instance 10 priority 0        //配置本机stp优先级，使其为vlan10的主根
    (=stp instance 10 priority root primary)
[S1]stp instance 20 priority 4096    //配置本机stp优先级，使其为vlan20的副根
    (=stp instance 20 priority root secondary)

注：关于mstp实例优先级的问题

stp instance 10 priority ?
? INTEGER<0-61440> ?Bridge priority, in steps of 4096?

缺省情况下为32768，步长为4096，越小越优先

?vrrp配置

[S1]int vlan 10
[S1-Vlanif10]ip add 192.168.10.252 24
[S1-Vlanif10]vrrp vrid 1 virtual-ip 192.168.10.254    //配置虚拟网关
[S1-Vlanif10]vrrp vrid 1 priority 120        //配置标识符1的优先级
[S1-Vlanif10]int vlan 20
[S1-Vlanif20]ip add 192.168.20.252 24
[S1-Vlanif20]vrrp vrid 2 virtual-ip 192.168.20.254

注：关于vrrp路由器标识符（vrid）优先级的问题

vrrp vrid 1 priority ?
? INTEGER<1-254> ?The level of priority(default is 100)

缺省情况下为100，越大越优先
