Caution:
To prevent the devices in the service provider network from processing the tunnel
packets as other protocol packets, the MAC address of a tunnel packet must be a
multicast address uniquely assigned to the BPDU tunnel in the service provider
network.

4.2 BPDU Tunnel Configuration

You can establish BPDU tunnels between S3100 series Ethernet switches for the
packets of the following protocols:
LACP (link aggregation control protocol)
STP (spanning tree protocol)
HGMP-related protocols, including: NDP (neighbor discovery protocol), NTDP
(neighbor topology discovery protocol), cluster MRC (cluster member remote
control), and HABP (Huawei authentication bypass protocol)
Proprietary protocols of other vendors, including CDP (CISCO discovery protocol),
PAGP (port aggregation protocol), PVST (per-VLAN spanning tree), VTP (VLAN
trunk protocol), and UDLD (uni-directional link discovery)
