Manual-mode MFF configuration example in a ring network
Network requirements
As shown in Figure 119, all the devices are in VLAN 100, and the switches form a ring. Hosts A, B, and
C are assigned IP addresses manually.
Configure MFF to isolate the hosts at Layer 2 and allow them to communicate with each other through
Gateway at Layer 3.
