vlan+vrrp+ stp

Posted 2020-09-27

拓扑图：

配置代码：

sw1------------

sys

vlan 10

vlan 20

quit

 

int e0/0/1

port link-type access

port default vlan 10

int e0/0/2

port link-type access

port default vlan 20

int e0/0/3

port link-type trunk

port trunk allow-pass vlan all

int e0/0/4

port link-type trunk

port trunk allow-pass vlan all

quit

 

(每个交换机都配)

stp region-configuration

region-name fxl

revision-level 1

instance 1 vlan 10

instance 2 vlan 20

active region-configuration

quit

 

sw2--------------

sys

vlan 10

vlan 20

quit

 

int e0/0/1

port link-type access

port default vlan 10

int e0/0/2

port link-type access

port default vlan 20

int e0/0/3

port link-type trunk

port trunk allow-pass vlan all

int e0/0/4

port link-type trunk

port trunk allow-pass vlan all

quit

 

stp region-configuration

region-name fxl

revision-level 1

instance 1 vlan 10

instance 2 vlan 20

active region-configuration

quit

 

sw3--------------

sys

vlan 10

vlan 20

quit

 

（g0/0/3和g0/0/4端口聚合）

interface eth-trunk 1

quit

interface g0/0/3

eth-trunk 1

quit

interface g0/0/4

eth-trunk 1

quit

interface eth-trunk 1

port link-type trunk

port trunk allow-pass vlan all

quit

 

int g0/0/1

port link-type trunk

port trunk allow-pass vlan all

int g0/0/2

port link-type trunk

port trunk allow-pass vlan all

quit

 

stp region-configuration

region-name fxl

revision-level 1

instance 1 vlan 10

instance 2 vlan 20

active region-configuration

quit

stp instance 1 priority 4096(配置stp使sw3成为vlan10的根)

 

 

(配置g0/0/5ip)

vlan 100

int vlanif 100

ip add 10.0.0.1 24

int g0/0/5

port link-type access

port default vlan 100

quit

 

(配置vrrp 使sw4down掉时数据可从sw3通过)

int vlanif 10（与sw4中的vlan10对比）

ip add 192.168.10.252 24

vrrp vrid 1 virtual-ip 192.168.10.254（sw3和sw4都配这虚拟ip）

vrrp vrid 1 priority 200（数据从优先级大的通过）

vrrp vrid 1 track interface g0/0/5 reduced 150

（配置端口追踪，当g0/0/5down掉时将vrid 优先级减150）

quit

 

int vlanif 20（与sw4中的vlan20对比）

ip add 192.168.20.252 24

vrrp vrid 2 virtual-ip 192.168.20.254

vrrp vrid 2 priority 150

quit

 

rip

version 2

network 192.168.10.0

network 192.168.20.0

network 10.0.0.0

quit

 

sw4--------------

vlan 10

vlan 20

quit

 

（g0/0/3和g0/0/4端口聚合）

quit

interface g0/0/3

eth-trunk 1

quit

interface g0/0/4

eth-trunk 1

quit

interface eth-trunk 1

port link-type trunk

port trunk allow-pass vlan all

quit

 

int g0/0/1

port link-type trunk

port trunk allow-pass vlan all

int g0/0/2

port link-type trunk

port trunk allow-pass vlan all

quit

 

(配置stp使sw4成为vlan20的根)

stp region-configuration

region-name fxl

revision-level 1

instance 1 vlan 10

instance 2 vlan 20

active region-configuration

quit

stp instance 2 priority 4096

 

 

(配置g0/0/5ip)

vlan 200

int vlanif 200

ip add 20.0.0.1 24

int g0/0/5

port link-type access

port default vlan 200

quit

 

int vlanif 10

ip add 192.168.10.253 24

vrrp vrid 1 virtual-ip 192.168.10.254

vrrp vrid 1 priority 150

quit

 

(配置vrrp 使sw4down掉时数据可从sw3通过)

int vlanif 20

ip add 192.168.20.253 24

vrrp vrid 2 virtual-ip 192.168.20.254

vrrp vrid 2 priority 200

vrrp vrid 2 track interface g0/0/5 reduced 150

quit

 

rip

R1---------

sys

int g0/0/0

ip add 10.0.0.2 24

int g0/0/1

ip add 20.0.0.2 24

int g0/0/2

ip add 30.0.0.254 24

quit

 

rip

version 2

network 10.0.0.0

network 20.0.0.0

network 30.0.0.0

quit

验证：

vlan10从sw3通过

Vlan20从sw4通过

把sw4down掉后：vlan20数据从sw3通过：

验证端口追踪：

把sw4端口g0/0/5down掉后：vlan20数据从sw3通过：
