1.1.4 MSTP Implementation on Switches
MSTP is compatible with both STP and RSTP. That is, MSTP-enabled switches can
recognize the protocol packets of STP and RSTP and use them for spanning tree
calculation. In addition to the basic MSTP functions, H3C series switches also provide
the following functions for the convenience of users to manage their switches:
z
Root bridge hold
z
Root bridge backup
z
Root protection
z
BPDU protection
z
Loop prevention
1.2 Configuring Root Bridge
Table 1-2 lists MSTP-related configurations about root bridges.
