Example: Configuring protocol-based VLANs
Network configuration
As shown in Figure 6:
• The majority of hosts in a lab environment run the IPv4 protocol.
• The other hosts run the IPv6 protocol for teaching purposes.
To isolate IPv4 and IPv6 traffic at Layer 2, configure protocol-based VLANs to associate the IPv4 and
ARP protocols with VLAN 100, and associate the IPv6 protocol with VLAN 200.
