【eNSP实战】MSTP与VRRP配合使用

拓扑图

要求：

PC1划分在vlan10；PC2划分在vlan20；主机IP和网关如图所示，这里不做展示
LSW1配置vlan10的根交换机，vlan20的备根交换机；LSW2配置vlan20的根交换机，vlan10的备根交换机
LSW1配置vlan10的VRRP作为vlan10 的网关；LSW2配置vlan20的VRRP作为vlan20的网关

LSW1配置vlan

vlan batch 10 20
#
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 10 20
#
interface GigabitEthernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan 10 20

LSW2配置vlan

vlan batch 10 20
#
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 10 20
#
interface GigabitEthernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan 10 20

LSW3配置vlan

vlan batch 10 20
#
interface Ethernet0/0/1
 port link-type access
 port default vlan 10
#
interface Ethernet0/0/2
 port link-type access
 port default vlan 20
#
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 10 20
#
interface GigabitEthernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan 10 20

下面开始配置MSTP

LSW1配置MSTP

stp mode mstp
#
stp region-configuration
 region-name re-mstp
 revision-level 1
 instance 1 vlan 10
 instance 2 vlan 20
 active region-configuration
#
stp instance 1 root primary
stp instance 2 root secondary

LSW2配置MSTP

stp mode mstp
#
stp region-configuration
 region-name re-mstp
 revision-level 1
 instance 1 vlan 10
 instance 2 vlan 20
 active region-configuration
#
stp instance 1 root secondary
stp instance 2 root primary

LSW3配置MSTP

stp mode mstp
#
stp region-configuration
 region-name re-mstp
 revision-level 1
 instance 1 vlan 10
 instance 2 vlan 20
 active region-configuration

下面开始配置VRRP

LSW1配置VRRP

interface Vlanif10
 ip address 192.168.10.253 255.255.255.0
 vrrp vrid 10 virtual-ip 192.168.10.1
 vrrp vrid 10 priority 120
 vrrp vrid 10 preempt-mode timer delay 30
#
interface Vlanif20
 ip address 192.168.20.253 255.255.255.0
 vrrp vrid 20 virtual-ip 192.168.20.1
 vrrp vrid 20 priority 100		# 设置优先级100（默认值是100，也可以不设置）

LSW2配置VRRP

interface Vlanif10
 ip address 192.168.10.254 255.255.255.0
 vrrp vrid 10 virtual-ip 192.168.10.1
 vrrp vrid 10 priority 100		# 设置优先级100（默认值是100，也可以不设置）
#
interface Vlanif20
 ip address 192.168.20.254 255.255.255.0
 vrrp vrid 20 virtual-ip 192.168.20.1
 vrrp vrid 20 priority 120
 vrrp vrid 20 preempt-mode timer delay 30

至此MSTP与VRRP配置完成，下面测试PC1 ping PC2
