双smart-link组

组网及说明

采用双smart-link组，实现两路冗余及流量负载均衡。

配置步骤

在SW1创建两个smart-link组

需要两个保护VLAN，这里提前规划，VLAN10作为smart-link组1的保护VLAN，VLAN20作为smart-link组2的保护VLAN

配置关键点

配置过程：

SW1：

[H3C]sysname SW1

[SW1]vl 10

[SW1-vlan10]qu

[SW1]vl 20

[SW1-vlan20]qu

[SW1]vl 30

[SW1-vlan30]qu

[SW1]vl 40

[SW1-vlan40]qu

[SW1]

[SW1]stp region-configuration

[SW1-mst-region]region-name H3C.COM

[SW1-mst-region]instance 0 vlan 10 30

[SW1-mst-region]instance 1 vlan 20 40

[SW1-mst-region]active region-configuration

[SW1-mst-region]quit

[SW1]int ran gi 1/0/1 to gi 1/0/2

[SW1-if-range]po li tr

[SW1-if-range]undo po tr pe vlan 1

[SW1-if-range]po tr pe vlan 10 20 30 40

[SW1-if-range]smart-link flush enable control-vlan 10 20

[SW1-if-range]undo stp en

[SW1-if-range]qu

[SW1]smart-link group 1

[SW1-smlk-group1]protected-vlan reference-instance 0

[SW1-smlk-group1]flush enable control-vlan 10

[SW1-smlk-group1]po gi 1/0/1 primary

[SW1-smlk-group1]po gi 1/0/2 secondary

[SW1-smlk-group1]quit

[SW1]

[SW1]smart-link group 2

[SW1-smlk-group2]protected-vlan reference-instance 1

[SW1-smlk-group2]flush enable control-vlan 20

[SW1-smlk-group2]port gi 1/0/2 primary

[SW1-smlk-group2]port GigabitEthernet 1/0/1 secondary

[SW1-smlk-group2]quit

[SW1]

SW2:

[H3C]sysname SW2

[SW2]vl 10

[SW2-vlan10]qu

[SW2]vl 20

[SW2-vlan20]qu

[SW2]vl 30

[SW2]int ran gi 1/0/1 to gi 1/0/2

[SW2-if-range]po li tr

[SW2-if-range]undo po tr pe vlan 1

[SW2-if-range]po tr pe vlan 10 20 30 40

[SW2-if-range]smart-link flush enable control-vlan 10 20

[SW2-if-range]quit

[SW2]monitor-link group 1

[SW2-mtlk-group1]port gi 1/0/1 uplink

[SW2-mtlk-group1]port gi 1/0/2 downlink

[SW2-mtlk-group1]quit

[SW3]vlan 10

[SW3-if-range]po li tr

[SW3-if-range]undo po tr pe vlan 1

[SW3-if-range]po tr pe vlan 10 20 30 40

[SW3-if-range]smart-link flush enable co

[SW3-if-range]smart-link flush enable control-vlan 10 20

[SW3-mtlk-group1]port GigabitEthernet 1/0/2 downlink

[SW3-mtlk-group1]quit

[SW3]

SW4（网关所在设备）:

[H3C]sysname SW4

[SW4]vlan 10

[SW4-vlan10]qu

[SW4]vlan 20

[SW4-vlan20]quit

[SW4]vlan 30
