Overview of STP, RSTP, and MSTP

Overview of STP, RSTP, and MSTP

This section describes the concepts of STP, RSTP, and MSTP.

STP and RSTP

STP

The IEEE 802.1D standard issued in 1998 defines STP.

STP is a management protocol on the data link layer and is used to detect and prevent loops on the local area network (LAN). STP blocks redundant links and trims a network into a tree topology to prevent loops.

However, an STP network converges slowly. A port, even an edge port, transits to the forwarding state after at least 30 seconds.

RSTP

The IEEE 802.1W standard issued in 2001 defines the RSTP.

As an enhancement of STP, RSTP speeds up network convergence.

However, both RSTP and STP have a defect, that is, all the VLANs on the same LAN share the same spanning tree. As a result, load balancing cannot be implemented among VLANs, and packets of some VLANs may fail to be forwarded.

As shown in Figure 2-9, RSTP is applied to the LAN. The structure of the spanning tree is represented by dotted lines and SwitchF is the root switch. The link between SwitchB and SwitchE and the link between SwitchA and SwitchD are blocked. Links of VLAN 2 and VLAN 3 permit packets from the two VLANs to pass through. Other links do not permit packets from VLAN 2 and VLAN 3 to pass through.

Figure 2-9 Defect of RSTP

Host A and Host B belong to VLAN 2. The link between SwitchB and SwitchE is blocked and the link between SwitchC and SwitchF does not permit packets from VLAN 2 to pass through. Therefore, Host A and Host B cannot communicate with each other.

MSTP

The IEEE 802.1S standard issued in 2002 defines MSTP.

MSTP is compatible with STP and RSTP and rectifies the defects of STP and RSTP. An MSTP network converges fast and provides redundant paths for data forwarding. In addition, the MSTP network implements load balancing among VLANs.

MSTP divides a switching network into multiple regions, each of which has multiple spanning trees independent of each other. Each spanning tree is called a multiple spanning tree instance (MSTI) and each region is called a multiple spanning tree (MST) region.

MSTP associates VLANs with MSTIs through a VLAN mapping table.

Each VLAN can be associated with only one MSTI, that is, data of the same VLAN can be transmitted in only one MSTI. One MSTI, however, may be associated with multiple VLANs.

MSTP is applied to the LAN, as shown in Figure 2-10, and then the MSTI is generated, as shown in Figure 2-10.

Figure 2-10 Spanning trees in an MST region

Two spanning trees are generated through calculation:

In MSTI 1, SwitchD functions as the root switch to forward packets of VLAN 2.

In MSTI 2, SwitchF functions as the root switch to forward packets of VLAN 3.

In this case, all VLANs can communicate, and packets of different VLANs are forwarded along different paths. Thus, load balancing is implemented.
