On all Cisco switches running RPVST+. On Huawei switches, instead of standard MSTP I run RSTP.
After I connected Huawei switch L2 and Cisco switch L3, the network start work incorrect. Huawei switch L3 do not see switch Cisco L3 and Each switch think him-self is root. I tried to set the Huawei switch as the root by reducing the priority, But it did not help.
