!--- ANSWER SCRIPT FOR ROUTER R1
!--- Usage: copy this whole file and paste it into the R1 terminal (start at the R1> prompt). Every line beginning with "!" is a comment; IOS ignores it, so pasting a comment by accident is harmless.

enable
configure terminal

! --------------------------------------------------------------
!--- Assign IP addressing to R1.
! --------------------------------------------------------------

!--- G0/0: /30 link toward the HQ network and the Server. The default route (S* 0.0.0.0/0 via G0/0) is preconfigured, so the Server is reachable once G0/0 is up.
interface gigabitethernet 0/0
 ip address 172.17.25.2 255.255.255.252
 no shutdown
 exit

! --------------------------------------------------------------
!--- Configure inter-VLAN routing on R1.
! --------------------------------------------------------------

!--- Enable the physical interface; the subinterfaces come up with it.
interface gigabitethernet 0/1
 no shutdown
 exit

!--- One 802.1Q subinterface per VLAN, gateway address from the Addressing Table.
interface gigabitethernet 0/1.10
 encapsulation dot1Q 10
 ip address 172.17.10.1 255.255.255.0
 exit
interface gigabitethernet 0/1.20
 encapsulation dot1Q 20
 ip address 172.17.20.1 255.255.255.0
 exit
interface gigabitethernet 0/1.30
 encapsulation dot1Q 30
 ip address 172.17.30.1 255.255.255.0
 exit

!--- VLAN 88 is the native VLAN on the S1 trunk, so this subinterface carries the "native" keyword.
interface gigabitethernet 0/1.88
 encapsulation dot1Q 88 native
 ip address 172.17.88.1 255.255.255.0
 exit

!--- VLAN 99: gateway for the S1 management SVI.
interface gigabitethernet 0/1.99
 encapsulation dot1Q 99
 ip address 172.17.99.1 255.255.255.0
 exit

end

! --------------------------------------------------------------
!--- Save the configuration to NVRAM. (Press Enter when prompted for the destination filename.)
! --------------------------------------------------------------
copy running-config startup-config


! ==============================================================
!--- Verification:
!---   show ip interface brief  -> G0/0, G0/1 and all five subinterfaces up/up
!---   show ip route            -> five connected /24 VLAN networks + 172.17.25.0/30, S* 0.0.0.0/0 via G0/0
!---   ping 172.17.99.10 (S1) and ping 172.17.50.254 (Server) -> successful

!--- Create, name, and assign VLANs.
! --------------------------------------------------------------

!--- VLAN names typed exactly as in the VLAN and Port Assignments Table.
vlan 10
 name Faculty/Staff
 exit
vlan 20
 name Students
 exit
vlan 30
 name Guest(Default)
 exit
vlan 88
 name Native
 exit
vlan 99
 name Management
 exit

!--- Access ports: F0/11-17 VLAN 10, F0/18-24 VLAN 20, F0/6-10 VLAN 30.
interface range fastethernet 0/11 - 17
 switchport mode access
 switchport access vlan 10
 exit
interface range fastethernet 0/18 - 24
 switchport mode access
 switchport access vlan 20
 exit
interface range fastethernet 0/6 - 10
 switchport mode access
 switchport access vlan 30

! --------------------------------------------------------------
!--- Configure G0/1 as a static trunk with native VLAN 88.
! --------------------------------------------------------------

interface gigabitethernet 0/1
 switchport mode trunk
 switchport trunk native vlan 88
 exit

! --------------------------------------------------------------
!--- Assign IP addressing and the default gateway on S1.
! --------------------------------------------------------------

!--- Management SVI in VLAN 99; R1 G0/1.99 is the default gateway.
interface vlan 99
 ip address 172.17.99.10 255.255.255.0
 no shutdown
 exit
ip default-gateway 172.17.99.1

! --------------------------------------------------------------
!--- Disable all ports that are not assigned to a VLAN.
! --------------------------------------------------------------

!--- F0/1-5 and G0/2 are the only unassigned ports.
interface range fastethernet 0/1 - 5, gigabitethernet 0/2
