华为设备配置MSTP+VRRP组合组网（h3cmstp和vrrp配置）

华为设备配置MSTP+VRRP组合组网（h3cmstp和vrrp配置）

1. 配置MSTP基本功能

配置LSW到域名为RG1的域内，创建实例MSTI1和实例MSTI2

[LSW1-mst-region]region-name RG1

[LSW1-mst-region]instance 1 vlan 10

[LSW1-mst-region]instance 2 vlan 20

[LSW1-mst-region]active region-configuration

[LSW2]stp region-configuration

[LSW2-mst-region]region-name RG1

[LSW2-mst-region]instance 1 vlan 10

[LSW2-mst-region]instance 2 vlan 20

[LSW2-mst-region]active region-configuration

[LSW3]stp region-configuration

[LSW3-mst-region]reg

[LSW3-mst-region]region-name RG1

[LSW3-mst-region]instance 1 vlan 10

[LSW3-mst-region]instance 2 vlan 20

[LSW3-mst-region]active region-configuration

在域RG1内，配置MSTI1与MSTI2的根桥与备份根桥

[LSW1]stp instance 1 root primary

[LSW1]stp instance 2 root secondary

[LSW2]stp instance 1 root secondary

[LSW2]stp instance 2 root primary

配置实例MSTI1和MSTI2中将要被阻塞端口的路径开销值大于缺省值

[LSW1]stp pathcost-standard legacy

[LSW2]stp pathcost-standard legacy

[LSW3]stp pathcost-standard legacy

[LSW3-GigabitEthernet0/0/1]stp instance 2 cost 20000

[LSW3-GigabitEthernet0/0/2]stp instance 1 cost 20000

使能MSTP，实现破除环路

[LSW1]stp enable

[LSW2]stp enable

[LSW3]stp enable

[LSW3-GigabitEthernet0/0/3]stp edged-port enable  //将与PC相连的端口设置为边缘端口

[LSW3-GigabitEthernet0/0/4]stp edged-port enable

[LSW3]stp bpdu-protection  //配置BPDU保护功能

[LSW1-GigabitEthernet0/0/1]stp edged-port enable

[LSW1]stp bpdu-protection

[LSW2-GigabitEthernet0/0/2]stp edged-port enable

[LSW2]stp bpdu-protection

2. 配置保护功能, 在各实例的根桥设备的指定端口配置根保护功能

[LSW1-GigabitEthernet0/0/3]stp root-protection

[LSW2-GigabitEthernet0/0/3]stp root-protection

3. 配置处于环网中的设备的二层转发功能

[LSW1]vlan batch 10 20

[LSW1-GigabitEthernet0/0/3]port link-type trunk

[LSW1-GigabitEthernet0/0/3]port trunk allow-pass vlan 10 20

[LSW1-GigabitEthernet0/0/2]port link-type trunk

[LSW1-GigabitEthernet0/0/2]port trunk allow-pass vlan 10 20

[LSW2]vlan batch 10 20

[LSW2-GigabitEthernet0/0/3]port link-type trunk

[LSW2-GigabitEthernet0/0/3]port trunk allow-pass vlan 10 20

[LSW2-GigabitEthernet0/0/1]port link-type trunk

[LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20

[LSW3]vlan batch 10 20

[LSW3-GigabitEthernet0/0/3]port link-type access

[LSW3-GigabitEthernet0/0/3]port default vlan 10

[LSW3-GigabitEthernet0/0/4]port link-type access

[LSW3-GigabitEthernet0/0/4]port default vlan 20

[LSW3-GigabitEthernet0/0/1]port link-type trunk

[LSW3-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20

[LSW3-GigabitEthernet0/0/2]port link-type trunk

[LSW3-GigabitEthernet0/0/2]port trunk allow-pass vlan 10 20

4. 验证配置

5. 配置设备间的网络互连

[LSW1]vlan batch 30

[LSW1-GigabitEthernet0/0/1]port link-type trunk

[LSW1-GigabitEthernet0/0/1]port trunk allow-pass vlan 30

[LSW1-Vlanif10]ip add 10.1.1.1 24

[LSW1-Vlanif20]ip add 10.1.2.1 24

[LSW1-Vlanif30]ip add 10.1.3.1 24

[LSW2]vlan batch 40

[LSW2-GigabitEthernet0/0/2]port link-type trunk

[LSW2-GigabitEthernet0/0/2]port trunk allow-pass vlan 40

[LSW2-Vlanif10]ip add 10.1.1.2 24

[LSW2-Vlanif20]ip add 10.1.2.2 24

[LSW2-Vlanif40]ip add 10.1.4.2 24

[LSW1]ospf 1

[LSW1-ospf-1]area 0

[LSW1-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255

[LSW1-ospf-1-area-0.0.0.0]network 10.1.2.0 0.0.0.255

[LSW1-ospf-1-area-0.0.0.0]network 10.1.3.0 0.0.0.255

[LSW2]ospf 1

[LSW2-ospf-1]area 0

[LSW2-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255

[LSW2-ospf-1-area-0.0.0.0]network 10.1.2.0 0.0.0.255

[LSW2-ospf-1-area-0.0.0.0]network 10.1.4.0 0.0.0.255

6. 配置VRRP备份组

[LSW1]int Vlanif 10

[LSW1-Vlanif10]vrrp vrid 1 virtual-ip 10.1.1.254

[LSW1-Vlanif10]vrrp vrid 1 priority 120

[LSW1-Vlanif10]vrrp vrid 1 preempt-mode timer delay 20

[LSW1]int Vlanif 20

[LSW1-Vlanif20]vrrp vrid 2 virtual-ip 10.1.2.254

[LSW2]int Vlanif 20

[LSW2-Vlanif20]vrrp vrid 2 virtual-ip 10.1.2.254

[LSW2-Vlanif20]vrrp vrid 2 priority 120

[LSW2-Vlanif20]vrrp vrid 2 preempt-mode timer delay 20

[LSW2]int Vlanif 10

[LSW2-Vlanif10]vrrp vrid 1 virtual-ip 10.1.1.254
