incompatibility between cisco and huawei?

In the attached file you will find the setup that we have to deal with.

As you can see, we have one MSTP region and we have configured one MSTP instance.

CISCO7604 is the MSTP root and Huawei8512 is the MSTP Backup root.

We are facing the following problem :

When there is a spanning tree change in Customer B's CPEs, the Catalyst 3750

send a Topology Change BPDU to the Huawei8505. As a result the Huawei8505 flushes

all MAC Addresses and Customer A's CPEs cannot communicate.

Since this is a QinQ topology this is not the expected behavior

because any change in the CPE shouldn't create a problem in the rest topology.

Are you aware of any incompatibility issue between Cisco and Huawei products?

Try this bug - CSCeg48603.

The command clear cef linecard slot can temporarily solve the problem.
