Basic Inter-VLAN Configuration Exercise<br />

Use Figure 9-3 to answer the following configuration scenario questions.<br />

Figure 9-3 Basic Inter-VLAN Configuration<br />

What does a router like RTA require in order to route between VLANs?<br />

It requires a Fast Ethernet interface <strong>and</strong> an IOS that supports inter-VLAN routing.<br />

Record the comm<strong>and</strong>s, including prompt, to configure RTA to route for all the VLANs shown in Figure 9-<br />

3. Use IEEE 802.1q encapsulation. Describe all interfaces <strong>and</strong> make sure you append the word native to<br />

the end of the encapsulation configuration for VLAN 1. Use the first available IP address in each network.<br />

RTA(config)#interface FastEthernet 0<br />

! Activate the physical interface if it won’t come up<br />

RTA(config-if)#no shutdown<br />

VLAN 1 192.168.1.0/24<br />

VLAN 100 192.168.100.0/24<br />

VLAN 200 192.168.200.0/24<br />

VLAN 300 192.168.300.0/24<br />

! Configure the Management VLAN 1. Don’t forget ‘native’<br />
