# Configure port Ethernet 2/3 as a trunk port, and assign it to VLANs 100 and 200, enabling

Ethernet 2/3 to forward packets of VLANs 100 and 200 to Router B.

[RouterA] interface ethernet 2/3

[RouterA-Ethernet2/3] port link-type trunk

[RouterA-Ethernet2/3] port trunk permit vlan 100 200

Please wait... Done.

2. Configure Router B in the same way Router A is configured.

3. Configure hosts:

{ Configure Host A and Host C to be on the same IP subnet. For example, 192.168.100.0/24.

{ Configure Host B and Host D to be on the same IP subnet. For example, 192.168.200.0/24.

Verifying the configuration

# Verify that Host A and Host C can ping each other, but they both fail to ping Host B.

# Verify that Host B and Host D can ping each other, but they both fail to ping Host A.

# Verify that VLANs 100 and 200 are correctly configured on Router A.
