the CIST root bridge priority and MAC address (eight bytes).
 CIST External Root Path Cost: CIST external root path cost, when only cross-domain
change in the propagation constant region (4 bytes).
 CIST Regional Root Identifier: CIST regional root bridge's unique identifier, the CIST
regional root bridge priority and the CIST regional root bridge MAC address, when
only cross-domain change in the spread within a fixed time (8 bytes ).
 CIST Port Identifier: MST BPDU packets to send the port identified by the port priority
and port ID component (2 bytes).
 Message Age: CIST root bridge is from this MST BPDU packets generated since the
time when the only cross-domain change in the propagation constant region (2 bytes).
 Max Age: MST BPDU message valid time, this parameter is set by the CIST root
bridge (2 bytes).
 Hello Time: CIST root bridge generates MST BPDU packet interval, this parameter is
set by the CIST root bridge (2 bytes).
 Forward Delay: forwarding delay, this parameter is set by the CIST root bridge (2
bytes).Its role is twofold:
 To be as a port state transition (from Discarding to Learning, from Learning to
Forwarding) protocol timer time; in the network topology changes, be as the dynamic
filtering database entry aging time.
 Version 1 Length: additional information, is fixed at 0 (1 byte).
 Version 3 Length: instructions from the MST BPDU configuration identification to the
end of length of the packet (2 bytes);
 MST Configuration Identifier: MST configuration identification, configuration selected
by the device, the configuration name, revision level and configuration summary form
only when the cross-domain changes in the propagation constant region (51 bytes).
 CIST Internal Root Path Cost: CIST internal root path cost, effective only in the
Ministry of MST region (4 bytes).
 CIST Bridge Identifier: sending MST BPDU packet bridge identified by the bridge
priority and MAC address of the bridge (8 bytes).
 CIST Remaining Hops: MST BPDU packets remaining in the CIST in the number of
hops (1 byte).
 MSTI Flags: identification of MSTI's main port, agreed to, forward, learning, port role,
suggested that the topology change state (1 byte).
 MSTI Regional Root Identifier: MSTI regional root bridge's unique identifier, the MSTI
regional root bridge priority, MSTID and MSTI regional root bridge MAC address, its
domain for different MSTI root bridge may be different (8 bytes).
