HP A5830 Configuration Manual page 105

 All ports that connect service provider devices and customer devices are access ports and belong to
VLAN 2. All ports that interconnect service provider devices are trunk ports and allow packets of any
VLAN to pass through.
MSTP is enabled on User A's network.

After the configuration, CE 1 and CE 2 must implement consistent spanning tree calculation across the
service provider network, and the destination multicast MAC address carried in BPDUs must be 0x0100-
0CCD-CDD0.
