Requirements
As shown above, an Intranet is divided into VLAN 10, VLAN 20 and VLAN 30 in
order to realize laye-2 isolation. The IP subnets corresponding to three VLANs
are 192.168.10.0/24, 192.168.20.0/24 and 192.168.30.0/24. The three VLANs
are interconnected through the IP forwarding capacity of layer-3 core switch.
5.5.3 Configuration
Tips
This example shows to how to configure the core switch and one of the access
switches:
Configure three VLANs on the core switch; configure the port connecting
access switch to trunk port and specify the allowed vlan list to realize
layer-2 isolation;
Configure three SVI interfaces on the core switch to serve as the gateway
interfaces for IP subnets corresponding to the three VLANs; configure the
corresponding IP addresses;
Create VLANs on three access switches and assign Access port for each
VLAN; specify the trunk port for connecting core switch. This example
shows the configuration steps on the access switch of Switch A.
