双归上行--主备/负载

主备

L1
创建vlan，划分接口（划分在l3）

vlan batch 2 to 3
stp enable
stp mode mstp
stp region-configuration 
region-name ZB
revision-level 1
instance 1 vlan 2 to 3
active region-configuration   //激活配置

stp instance 1 root primary 

L2

vlan batch 2 to 3

stp region-configuration 
region-name ZB
revision-level 1
instance 1 vlan 2 to 3
active region-configuration 

stp instance 1 root secondary

L3

vlan batch 2 to 3

port-group group-member g0/0/1 to g0/0/9
port link-type access 
port default vlan 2

port-group group-member g0/0/10 to g0/0/19
port link-type access 
port default vlan 3

int g0/0/23
port link-type trunk 
undo port trunk allow-pass vlan 1  //防止VLAN1出环

int g0/0/24
port link-type trunk 
undo port trunk allow-pass vlan 1

负载

L4

vlan batch 2 to 3

int eth-trunk 1
trunkport g0/0/1
trunkport g0/0/2

stp enable
stp mode mstp
stp region-configuration
region-name FZ
revision-level 1
instance 1 vlan 2 
instance 2 vlan 3
active region-configuration
stp instance 1 root primary //设置为vlan2主根桥
stp instance 2 root secondary //设置为vlan3的备根桥

L5

vlan batch 2 to 3

int eth-trunk 1
trunkport g0/0/1
trunkport g0/0/2


stp region-configuration
region-name FZ
revision-level 1
instance 1 vlan 2 
instance 2 vlan 3
active region-configuration
stp instance 1 root secondary //设置为vlan2备根桥
stp instance 2 root primary //设置为vlan3的主根桥

L6

vlan batch 2 to 3

port link-type access 
port default vlan 3

int g0/0/23
