5.16.5 STP family (STP, RSTP, MSTP)
The main task of STP (Spanning Tree Protocol) is to convert an Ethernet network with multiple links
into a spanning tree loop-free topology. Switches exchange configuration messages using frames in a
specific format and selectively enable or disable traffic transmission to ports.
Rapid STP (RSTP) is the enhanced version of STP that enables faster convergence of a network to a
spanning tree topology and provides higher stability.
Multiple STP (MSTP) is the most recent implementation of STP that supports VLAN. MSTP
configures required number of spanning trees independent on the number of VLAN groups on the switch.
Each instance may contain multiple VLAN groups. However, one drawback of MSTP it that all MSTP
switches should have the same VLAN group configuration.
Max available number of the MSTP instances is specified in the Table 2.9. Main
specifications.
