MSTP-VRRP-DHCP-OSPF-BFD实验(二)

所有交换机需启用MSTP服务

[JR_SW7]stp region-configuration 
[JR_SW7-mst-region]region-name aa
[JR_SW7-mst-region]revision-level 1
[JR_SW7-mst-region]instance 1 vlan 2 3 200
[JR_SW7-mst-region]instance 2 vlan 4 5 6
[JR_SW7-mst-region]active region-configuration 
Info: This operation may take a few seconds. Please wait for a moment...done.

核心交换机1配置MSTP

[HX_SW1]stp region-configuration 
[HX_SW1-mst-region]region-name aa
[HX_SW1-mst-region]revision-level 1
[HX_SW1-mst-region]instance 1 vlan 2 3 200
[HX_SW1-mst-region]instance 2 vlan 4 5 6
[HX_SW1-mst-region]active region-configuration 
Info: This operation may take a few seconds. Please wait for a moment...done.
[HX_SW1-mst-region]dis this
#
stp region-configuration
 region-name aa
 revision-level 1
 instance 1 vlan 2 to 3 200
 instance 2 vlan 4 to 6
 active region-configuration
#
return
[HX_SW1-mst-region]

--------配置主次-----------------
[HX_SW1]stp instance 1 root primary 
[HX_SW1]stp instance 2 root secondary 

配置核心交换机2MSTP

[HX_SW2]stp region-configuration 
[HX_SW2-mst-region]region-name aa
[HX_SW2-mst-region]revision-level 1
[HX_SW2-mst-region]instance 1 vlan 2 3 200

return
[HX_SW2-mst-region]active region-configuration 
Info: This operation may take a few seconds. Please wait for a moment...done.
