Implementation Of Mstp On Devices; Protocols And Standards; Mstp Configuration Task List - HP A6600 Configuration Manual

How STP works."
In MSTP, a VLAN packet is forwarded along the following paths:
Within an MST region, the packet is forwarded along the corresponding MSTI.
•
Between two MST regions, the packet is forwarded along the CST.
•

Implementation of MSTP on devices

MSTP is compatible with STP and RSTP. STP and RSTP protocol packets can be recognized by devices
running MSTP and used for spanning tree calculation.
In addition to basic MSTP functions, many special functions are provided for ease of management, as
follows:
Root bridge hold
•
Root bridge backup
•
Root guard
•
BPDU guard
•
Loop guard
•
TC-BPDU guard
•
BPDU drop
•
Support for hot swapping of interface cards and active/standby changeover.
•

Protocols and standards

MSTP is documented in:
• IEEE 802.1d: Media Access Control (MAC) Bridges
• IEEE 802.1w: Part 3: Media Access Control (MAC) Bridges—Amendment 2: Rapid Reconfiguration
• IEEE 802.1s: Virtual Bridged Local Area Networks—Amendment 3: Multiple Spanning Trees

MSTP configuration task list

Before configuring MSTP, you need to know the role of each device in each MSTI: root bridge or leave
node. In each MSTI, one, and only one device acts as the root bridge, while all others as leaf nodes.
Complete these tasks to configure MSTP:
Task
Configuring the root
bridge
Configuring an MST region
Configuring the root bridge or a secondary root bridge
Configuring the work mode of an MSTP device
Configuring the priority of a device
Configuring the maximum hops of an MST region
Configuring the network diameter of a switched network
Configuring timers of MSTP
Configuring the timeout factor
