Quidway S7700 Smart Routing Switch
Configuration Guide - Ethernet
MSTP can be deployed on a network to eliminate loops. If a loop is detected, MSTP blocks one
or more ports to eliminate the loop. In addition, MSTIs can be configured to load-balance VLAN
traffic.
As shown in
MSTI 1 and MSTI 2, configure a root bridge for each MSTI, and set the ports to be blocked to
load-balance traffic of VLANs 1 to 10 and VLANs 11 to 20 among different paths.
