Dear all,

    In the following test case:

                                    R1 ----------- Cat3550 ---------- R3
                                     | |
                                    R2 ----------------

   R1 and R2's Ethernet are connected to Cat3550, but connect to ports of
differnt VLANs, R3 is connect to the same VLAN with R1.

   R1 and R2's Serial are connected together.

   I then try to connect the dlsw between R1 and R2's Ethernet interface.
However once I have configure the DLSW peers and put the Ethernet interface
into the bridge group, the Ethernet of the R1 are not functioning. The
result of "sh int" show the interface of both R1 and Cat3550 is up, but R1
cannot ping R3. Anyone know how to solve this problem? The configure is
simple and works fine if I don't use Cat3550 to connect the routers.

Best Regards,
William
