configure the port connected to the Router as a trunk port.
Switch1(config)# interface range fast0/5 – 10
Switch1(config-if-range)# switchport trunk encapsulation dot1q
Switch1(config-if-range)# switchport trunk native vlan 10
Switch1(config-if-range)# switchport mode trunk
Switch1(config-if-range)# switchport voice vlan 15
Switch1(config-if-range)# no shut
Switch1(config)# interface fast0/1
Switch1(config-if-range)# switchport trunk encapsulation dot1q
Switch1(config-if-range)# switchport mode trunk
Switch1(config-if-range)# no shut
e. Configure the switch2 (connected to R2) in a similar way.
Switch2# delete flash:vlan.dat
Switch2# erase startup-config
Switch2# reload
Switch2# vlan database
Switch2(vlan)# vlan 20 name DATA state active
Switch2(vlan)# vlan 25 name VOICE state active
Switch2(vlan)# exit
Switch2(config)# interface range fast0/5 – 10
Switch2(config-if-range)# switchport trunk encapsulation dot1q
Switch2(config-if-range)# switchport trunk native vlan 20
Switch2(config-if-range)# switchport mode trunk
Switch2(config-if-range)# switchport voice vlan 25
Switch2(config-if-range)# no shut
Switch2(config)# interface fast0/1
Switch2(config-if-range)# switchport trunk encapsulation dot1q
Switch2(config-if-range)# switchport mode trunk
Switch2(config-if-range)# no shut

m.
Enter privilege exec mode.
n. Configure the hostname, passwords, interfaces, console and telnet access, eigrp routing
protocol like the figure and make sure that both routers can reach each other. Use the
ping command to troubleshoot, if necessary. The R1 and R2 configuration files are listed
