配置MSTP使图1-7中不同VLAN的报文按照不同的生成树实例转发。具体配置为:
l 网络中所有交换机属于同一个MST域;
l VLAN 10的报文沿着实例1转发,VLAN 30沿着实例3转发,VLAN 40沿着实例4转发,VLAN 20沿着实例0转发。
图1-7中Switch A和Switch B为汇聚层设备,Switch C和Switch D为接入层设备。VLAN 10、VLAN30在汇聚层设备终结,VLAN 40在接入层设备终结,因此可以配置实例1和实例3的树根分别为Switch A和Switch B,实例4的树根为Switch C。
图1-7 MSTP配置组网图
& 说明:
图1-7中链路上的说明“permit: ”表示该链路允许哪些VLAN的报文通过。
(1) 配置Switch A
# 进入 MST域视图。
<H3C> system-view
System View: return to User View with Ctrl+Z.
[H3C] stp region-configuration
# 配置 MST域。
[H3C-mst-region] region-name example
[H3C-mst-region] instance 1 vlan 10
[H3C-mst-region] instance 3 vlan 30
[H3C-mst-region] instance 4 vlan 40
[H3C-mst-region] revision-level 0
# 手工激活MST域的配置。
[H3C-mst-region] active region-configuration
# 定义Switch A为实例1的树根。
[H3C] stp instance 1 root primary
(2) 配置Switch B
# 进入 MST域视图。
<H3C> system-view
System View: return to User View with Ctrl+Z.
[H3C] stp region-configuration
# 配置 MST域。
[H3C-mst-region] region-name example
[H3C-mst-region] instance 1 vlan 10
[H3C-mst-region] instance 3 vlan 30
[H3C-mst-region] instance 4 vlan 40
[H3C-mst-region] revision-level 0
# 手工激活MST域的配置。
[H3C-mst-region] active region-configuration
# 定义Switch B为实例3的树根。
[H3C] stp instance 3 root primary
(3) 配置Switch C
# MST域。
<H3C> system-view
System View: return to User View with Ctrl+Z.
[H3C] stp region-configuration
[H3C-mst-region] region-name example
[H3C-mst-region] instance 1 vlan 10
[H3C-mst-region] instance 3 vlan 30
[H3C-mst-region] instance 4 vlan 40
[H3C-mst-region] revision-level 0
# 手工激活MST域的配置。
[H3C-mst-region] active region-configuration
# 定义Switch C为实例4的树根。
[H3C] stp instance 4 root primary
(4) 配置Switch D
# 进入MST域视图。
<H3C> system-view
System View: return to User View with Ctrl+Z.
[H3C] stp region-configuration
# 配置 MST域。
[H3C-mst-region] region-name example
[H3C-mst-region] instance 1 vlan 10
[H3C-mst-region] instance 3 vlan 30
[H3C-mst-region] instance 4 vlan 40
