华为企业组网实例:VRRP+MSTP典型组网配置

VRRP+MSTP典型组网配置

VRRP是一种容错协议,它保证当主机的下一跳路由器出现故障时,由另一台路由器来代替出现故障的路由器进行工作,从而保持网络通信的连续性和可靠性。

MSTP:多生成树协议,通过生成多个生成树,来解决以太网环路问题。

实验拓扑

在这里插入图片描述

一、VLAN配置

SW3配置

sy sw3
un in en
vlan batch 10 20 30 40 
interface g0/0/2
 port link-type access
 port default vlan 10
 q
interface g0/0/3
 port link-type access
 port default vlan 20

SW4配置

sy sw4
un in en
vlan batch 10 20 30 40
interface g0/0/2
 port link-type access
 port default vlan 30
 q
interface g0/0/3
 port link-type access
 port default vlan 40
 q

二、Trunk配置

SW3配置

interface g0/0/1
 port link-type trunk
 port trunk allow-pass vlan 10 20
 
interface g0/0/4
 port link-type trunk
 port trunk allow-pass vlan 10 20

SW4配置

interface g0/0/1
 port link-type trunk
 port trunk allow-pass vlan 30 40
 q
interface g0/0/4
 port link-type trunk
 port trunk allow-pass vlan 30 40
 q

SW1配置

sy sw1
un in en
vlan batch 10 20 30 40

interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 10 20
 
interface GigabitEthernet0/0/3
 port link-type trunk
 port trunk allow-pass vlan 30 40

SW2配置

sy sw2
un in en
vlan batch 10 20 30 40

interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 30 40
 
interface GigabitEthernet0/0/3
 port link-type trunk
 port trunk allow-pass vlan 10 20

三、链路聚合

SW1和SW2之间我们用两根网线,做成链路聚合。

SW1配置

[hxsw1]int Eth-Trunk 1
[hxsw1-Eth-Trunk1]mode lacp-static
[hxsw1-Eth-Trunk1]trunkport g0/0/2
Info: This operation may take a few seconds. Please wait for a moment...done.
[hxsw1-Eth-Trunk1]trunkport g0/0/5
Info: This operation may take a few seconds. Please wait for a moment...done.

SW2配置

[hxsw2]int Eth-Trunk 1
[hxsw2-Eth-Trunk1]mode lacp-static 	
[hxsw2-Eth-Trunk1]trunkport g0/0/2
Info: This operation may take a few seconds. Please wait for a moment...done.
[hxsw2-Eth-Trunk1]trunkport g0/0/5
Info: This operation may take a few seconds. Please wait for a moment...done.
[hxsw2-Eth-Trunk1]

验证查看:

[hxsw1]dis eth-trunk 
Eth-Trunk1's state information is:
Local:
LAG ID: 1                   WorkingMode: STATIC                               
Preempt Delay: Disabled     Hash arithmetic: According to SIP-XOR-DIP         
System Priority: 32768      System ID: 4c1f-cc6a-6dff                         
Least Active-linknumber: 1  Max Active-linknumber: 8                          
Operate status: up          Number Of Up Port In Trunk: 2

GigabitEthernet0/0/5   Selected 1GE      32768   6      305     10111100  1     

Partner:
--------------------------------------------------------------------------------

GigabitEthernet0/0/5   32768    4c1f-ccb4-3bac  32768   6      305     10111100
    
[hxsw1]

配置trunk,允许所有vlan通过

sw1

[sw1]int Eth-Trunk 1
[sw1-Eth-Trunk1]port link-type trunk 
[sw1-Eth-Trunk1]port trunk allow-pass vlan 10 20 30 40

sw2

[sw2]int Eth-Trunk 1
[sw2-Eth-Trunk1]port link-type trunk
[sw2-Eth-Trunk1]port trunk allow-pass vlan 10 20 30 40

四、MSTP配置

公共配置

以下步骤必须在所有的有冗余的交换机上做,我们没有汇聚就算了,但是我们接入交换机有冗余所以要做。

stp region-configuration
 region-name pokes01    #域名pokes01
 revision-level 1       #修订好统一为1
 instance 1 vlan 10 20  #将vlan10/20映射到实例1里面
 instance 2 vlan 30 40
 active region-configuration  #激活才能生效
 q

纯净版便于复制

stp region-configuration
 region-name pokes01
 revision-level 1
 instance 1 vlan 10 20
 instance 2 vlan 30 40
 active region-configuration
 q

SW1配置

stp instance 1 root primary 	 #将SW1作为实例1的根桥
stp instance 2 root secondary    #将SW1作为实例2的备份根桥

SW2配置

stp instance 1 root secondary
stp instance 2 root primary

分别在SW3、SW4上面验证

SW3配置

在下面的查看中,我们看不到实例2,那是因为我们在SW3的trunk没有允许VLAN30/40通过

[sw3]dis stp brief
 MSTID  Port                        Role  STP State     Protection

   2    GigabitEthernet0/0/4        DESI  FORWARDING      NONE

SW4配置

在下面的查看中,我们看不到实例1,那是因为我们在SW3的trunk没有允许VLAN10/20通过

[sw4]dis stp brief
 MSTID  Port                        Role  STP State     Protection

   0    GigabitEthernet0/0/4        ROOT  FORWARDING      NONE
   1    GigabitEthernet0/0/1        DESI  FORWARDING      NONE
   1    GigabitEthernet0/0/4        DESI  FORWARDING      NONE
   2    GigabitEthernet0/0/1        ROOT  FORWARDING      NONE

   2    GigabitEthernet0/0/4        ALTE  DISCARDING      NONE

五、VRRP配置

sw1配置

interface Vlanif10
 ip address 192.168.10.253 255.255.255.0
 vrrp vrid 10 virtual-ip 192.168.10.1

 ip address 192.168.40.253 255.255.255.0
 vrrp vrid 40 virtual-ip 192.168.40.1
 

sw2配置

interface Vlanif10
 ip address 192.168.10.254 255.255.255.0
 vrrp vrid 10 virtual-ip 192.168.10.1

 vrrp vrid 40 virtual-ip 192.168.40.1
 vrrp vrid 40 priority 120

检测验证

六、VRRP+MSTP的注意事项

  • 拓扑图中所有的交换机都要创建vlan10/20/30/40
  • sw1和sw2之间的聚合链路,两头都要配置。

八、路由器配置

SW1

[sw1]vlan 800
[sw1-vlan800]q
[sw1]int vlanif800
[sw1-Vlanif800]ip add 192.168.12.2 24
[sw1-Vlanif800]q

SW2

[sw2]vlan 801
[sw2-vlan801]q	
[sw2]int Vlanif 801
[sw2-Vlanif801]ip add 192.168.23.2 24
[sw2-Vlanif801]q

R1

[Huawei]sysname R1
[R1]un in en
[R1]in g0/0/0
[R1-GigabitEthernet0/0/0]ip add 192.168.12.1 24

[R1]in g0/0/1
[R1-GigabitEthernet0/0/1]ip add 192.168.23.1 24
[R1-GigabitEthernet0/0/1]q
[R1]q

九、BGP跟踪的配置

作用:当设备假死的时候,我们使它能够自动切换。

[sw1]bfd      #启用
[sw1-bfd]q
[sw1]bf	
[sw1]bfd szpr01 bind peer-ip 192.168.12.1 source-ip 192.168.12.2 auto   
[sw1-bfd-session-szpr01]com	
[sw1-bfd-session-szpr01]commit 
  • szpr01是我起的名字
  • peer-ip是对端地址
  • source-ip是本地地址
[R1]bfd
[R1-bfd]q	
[R1]bfd szpr01 bind peer-ip 192.168.12.2 source-ip 192.168.12.1 auto 
[R1-bfd-session-szpr02]commit 

注意:在这里szpr01的名字,要和SW1上一致。

查看

[sw1]dis bfd session all
--------------------------------------------------------------------------------
Local Remote     PeerIpAddr      State     Type        InterfaceName            
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
