1.1.4 MSTP Implementation on Switches

MSTP is compatible with both STP and RSTP. That is, switches with MSTP employed
can recognize the protocol packets of STP and RSTP and use them to generate
spanning trees. In addition to the basic MSTP functions, Quidway series switches also
provide the following other functions for the convenience of users to manage their
switches.
Root bridge retaining
Root bridge backup
Root protection
BPDU protection
Loop prevention
