Can you just create a static cam entry for the mst bpdu well-know multicast
mac address on each 3750 10 port?

Subject: ISP Scalability Feature
Hi GS:
Here is what I am trying to do. Those of you familiar with scalability
testing probably have heard of Ixia - and also know how expensive these
boxes are. We are testing the L2Protocol-Tunnel feature in CATOS (there are
a few people who still use CATOS). Because of the high per-port cost on
Ixia, we want to use a single Ixia port, sending MST BPDUs, where it will
hit a 3750 Metro and equally balance the BPDUs between ten ports, each
connected to a testbed of 6506's. We either need to cause the switch to
flood the packets out all 10 ports or find a way to direct them equally out
each port. Any thoughts?
Thanks in advance
