Cisco & Huawei QinQ interworking

Hello Everybody,

 

I made have 3 different configuration scenarios. Please find below.

Scen 1. STP works perfectly, PagP channel forms.

Scen 2  STP works perfectly, PagP channel does not form.

Scen 3 nothing works, both SW4 and SW3 think they are the Root Bridge for Vlan 100

Config:

MTU is 1600 for ETH links and 9000 for Gig links
