H3C与HP交换机MSTP互联典型配置

H3C交换机与HP交换机MSTP互联典型配置

 

一    组网需求：

SW-B和SW-C为H3C交换机，充当核心层设备。SW-A为HP交换机，充当接入层设备分别双上联到SW-B和SW-C。三台交换机运行MSTP协议，SW-B为实例0和实例2的主根，实例1的备根；SW-C为实例1的主根，实例0和实例2的备根。不同的VLAN按照不同的生成树实例转发。

instance 0：VLAN 1

instance 1：VLAN 2

instance 2：VLAN 5

二    组网图：

三    配置步骤：

SW-A：

spanning-tree

spanning-tree config-name "abc"

spanning-tree instance 1 vlan 2

spanning-tree instance 2 vlan 5

vlan 1

   name "DEFAULT_VLAN"

   tagged 1-2

   exit

vlan 2

   name "VLAN2"

   tagged 1-2

   exit

vlan 5

   name "VLAN5"

   tagged 1-2

   exit

 

SW-B：

stp instance 0 root primary

stp instance 1 root secondary

stp instance 2 root primary

stp enable

stp region-configuration

 region-name abc

 instance 1 vlan 2

 instance 2 vlan 5

 active region-configuration

interface Ethernet1/0/1

 port link-type trunk

 port trunk permit vlan 1 to 2 5

interface Ethernet1/0/2

 port link-type trunk

 port trunk permit vlan 1 to 2 5

 

SW-C：

stp instance 0 root secondary

stp instance 1 root primary

stp instance 2 root secondary

stp enable

stp region-configuration

 region-name abc

 instance 1 vlan 2

 instance 2 vlan 5

 active region-configuration

interface Ethernet1/0/1

 port link-type trunk

 port trunk permit vlan 1 to 2 5

interface Ethernet1/0/2

 port link-type trunk

 port trunk permit vlan 1 to 2 5

SW-A(config)# show spanning-tree instance 2

  Port    Type        Cost      Priority   Role       State

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

  1      10/100TX    200000    128      Root       Forwarding
