问题描述：

组网及组网描述：

做了MSTP 设置S1做为VLAN 88、100的主根，S6为vlan40 50 的主根，但是BAG99聚合端口还是阻塞的，

将BAG99聚合端口的STP关掉后，网络恢复正常，要怎么解决？

配置文件如下，BAG99是阻塞的

stp region-configuration

region-name neiwang

instance 1 vlan 100

instance 4 vlan 88

active region-configuration

stp instance 1 4 root primary

stp global enable

用RRPP或者OSPF做三层环

回复zhiliao_f6aW5T:

可以解决呀V9293357

这是网络改造，S2原本是波分，现在改用交换机做互联。除这S1和S2之外还有其他的网络。S1和S2一个是核心，一个是汇聚

配置问题，mstp按图上组网是没有问题的

不好意思，配置重新写在下面了
