Configuring Protocol VLAN Configuration Example

Configuration Example
3.1 Network Requirements
A company uses both IPv4 and IPv6 hosts, and these hosts access the IPv4 network
and IPv6 network respectively via different routers. It is required that IPv4 packets are
forwarded to the IPv4 network, IPv6 packets are forwarded to the IPv6 network, and other
packets are dropped.
The figure below shows the network topology. The IPv4 host belongs to VLAN 10, the IPv6
host belongs to VLAN 20, and these hosts access the network via Switch 1. Switch 2 is
connected to two routers to access the IPv4 network and IPv6 network respectively. The
routers belong to VLAN 10 and VLAN 20 respectively.

When this port receives packets, Switch 2 will forward them to the corresponding VLANs
according to their protocol types. The overview of the configuration on Switch 2 is as
follows:
