Configure the isolation group so that the two layers cannot communicate with each other, but both can communicate with the outside.
1. Networking requirements
As shown in the figure, the community users Host A, Host B and Host C are respectively connected to the Device ports GigabitEthernet 1-0-1, GigabitEthernet 1-0-2 and GigabitEthernet 1-0-3, and the Device equipment is connected to the external network through the GigabitEthernet 1-0-4 port. Now it is necessary to realize that the two-layer messages of Host A, Host B and Host C can not communicate with each other, but can communicate with the external network.
two。 The configuration steps and verification configuration are shown in the figure
3. The verification result is shown in the figure
