Using the Cisco Packet Tracer PART I: Getting to the Internet from the Inside – a walk through 1. Disable ospf on R1 & SW1 (OPEN SHORTEST PATH FIRST) a. conf t then no router ospf 1 2. Enable default gateway (gateway of last resort) on R1 192.168.1.1 a. conf t then ip route 0.0.0.0 0.0.0.0 192.168.1.1 b. Ping to test 23.1.2.2 Try from SW1 and Fail 3. Enable ospf on R1 & SW1 a. router ospf 1 b. net 0.0.0.0 255.255.255.255 area 0 and then show “O” for ospf (fast forward) c. run show ip ospf 4. On R1, conf t a. router ospf 1 and then default-information originate (propagates default gateway) b. show default gateway is now on SW1 5. Can SW1 ping 23.1.2.2? Why not? a. Because Home Router (Linksys cheapo) does not know how to get to the 172.16.0.0 network HAS NO WAY OF FINDING IT AND THIS ROUTER DOESN’T SUPPORT IT 6. Instead, let’s do some natting (NAT = Network Access Translation) on R1 7. On R1, show access-lists (in case there’s one already) a. conf t and access-list 1 permit 172.16.0.0 0.0.255.255 i. the 0.0.255.255 means we don’t care anything about the last 2 octets b. ip nat inside source list 1 interface g 0/0 overload (“overload” so we can have thousands of addresses map to a single outside address) i. int gig 0/0 and then ip nat outside ii. int gig 0/1 then ip nat inside and exit 8. Now let’s verify SW1 can get to the internet a. ping 23.1.2.2 Successful? 9. Go to PC2. Ping and then browse to thekeithbarker.com Successful? a. Go to R1 and run show ip nat translation What do you see? Which ports? PART TWO: Setting up VLANs and getting PCs working correctly  partial walk-through Professor + Students setting up VLANs and getting PCs working correctly --> Partial walk-through 1. Now let’s create a VLAN and add a PC to that VLAN (A VLAN is a Virtual Local Area Network) b. Note that when we run sh run on SW1 and hit the space bar we see under interface VLANs 1-3 is ip helper-address 172.16.4.2 -->This is the DHCP server which automatically hands out IP addresses. c. On SW1, conf t and vlan 5 You’ll see Vlan5 com up a. Type name Students then do sh vlan Do you see your new vlan named Students? b. Exit and int vlan 5 Then assign the ip address 172.16.5.1 255.255.255.0 c. While in the SVI (switched virtual interface) assign the ip helper-address 172.16.4.2 d. Now, to the Lab Server and DHCP service and set up your new VLAN. Use the others alreadyconfigured to help you out. e. Add a new Laptop or PC to SW2 (a layer2 switch), connect it and name the PC Student. Is it getting anIP address? Set it to DHCP. Is it getting a Student IP address (VLAN5)? Remember 172.16.5.0/24 i. Log into SW2 and let’s fix this sh vlan and notice Students has no interfaces assigned. ii. Add Fa 0/5 conf t then int fa 0/5 (or the int the PC is connected to) and sw acc vlan5 iii. exit and sh vlan You’ll see Students (VLAN5) know has Fa0/5 added to it. iv. Check the PC, toggle IP to static and back to DHCP to get a 172.16.5.0/24 address Students 2. Now repeat the above steps for two new VLANs a. VLAN 6, name it Guest b. VLAN 7, name it DMZ Don’t forget to IP the VLANs on SW1, add a PC to each new interface on SW2 – one to each new SVI – and setthe DHCP scope (options) on the Lab Server. Make sure each PC gets the correct corresponding IP address.Make sure to save your packet tracer lab work.

Question

Using the Cisco Packet Tracer

PART I:

Getting to the Internet from the Inside – a walk through

1. Disable ospf on R1 & SW1 (OPEN SHORTEST PATH FIRST)

a. conf t then no router ospf 1

2. Enable default gateway (gateway of last resort) on R1 192.168.1.1

a. conf t then ip route 0.0.0.0 0.0.0.0 192.168.1.1

b. Ping to test 23.1.2.2 Try from SW1 and Fail

3. Enable ospf on R1 & SW1

a. router ospf 1

b. net 0.0.0.0 255.255.255.255 area 0 and then show “O” for ospf (fast forward)

c. run show ip ospf

4. On R1, conf t

a. router ospf 1 and then default-information originate (propagates default gateway)

b. show default gateway is now on SW1

5. Can SW1 ping 23.1.2.2? Why not?

a. Because Home Router (Linksys cheapo) does not know how to get to the 172.16.0.0 network HAS NO WAY OF FINDING IT AND THIS ROUTER DOESN’T SUPPORT IT

6. Instead, let’s do some natting (NAT = Network Access Translation) on R1

7. On R1, show access-lists (in case there’s one already)

a. conf t and access-list 1 permit 172.16.0.0 0.0.255.255

i. the 0.0.255.255 means we don’t care anything about the last 2 octets

b. ip nat inside source list 1 interface g 0/0 overload (“overload” so we can have thousands of addresses map to a single outside address)

i. int gig 0/0 and then ip nat outside

ii. int gig 0/1 then ip nat inside and exit

8. Now let’s verify SW1 can get to the internet

a. ping 23.1.2.2 Successful?

9. Go to PC2. Ping and then browse to thekeithbarker.com Successful?

a. Go to R1 and run show ip nat translation What do you see? Which ports?

PART TWO: Setting up VLANs and getting PCs working correctly  partial walk-through

Professor + Students

setting up VLANs and getting PCs working correctly --> Partial walk-through

1. Now let’s create a VLAN and add a PC to that VLAN (A VLAN is a Virtual Local Area Network)

b. Note that when we run sh run on SW1 and hit the space bar we see under interface VLANs 1-3 is ip helper-address 172.16.4.2 -->This is the DHCP server which automatically hands out IP addresses.

c. On SW1, conf t and vlan 5 You’ll see Vlan5 com up

a. Type name Students then do sh vlan Do you see your new vlan named Students?

b. Exit and int vlan 5 Then assign the ip address 172.16.5.1 255.255.255.0

c. While in the SVI (switched virtual interface) assign the ip helper-address 172.16.4.2

d. Now, to the Lab Server and DHCP service and set up your new VLAN. Use the others alreadyconfigured to help you out.

e. Add a new Laptop or PC to SW2 (a layer2 switch), connect it and name the PC Student. Is it getting anIP address? Set it to DHCP. Is it getting a Student IP address (VLAN5)? Remember 172.16.5.0/24

i. Log into SW2 and let’s fix this sh vlan and notice Students has no interfaces assigned.

ii. Add Fa 0/5 conf t then int fa 0/5 (or the int the PC is connected to) and sw acc vlan5

iii. exit and sh vlan You’ll see Students (VLAN5) know has Fa0/5 added to it.

iv. Check the PC, toggle IP to static and back to DHCP to get a 172.16.5.0/24 address

Students

2. Now repeat the above steps for two new VLANs

a. VLAN 6, name it Guest

b. VLAN 7, name it DMZ

Don’t forget to IP the VLANs on SW1, add a PC to each new interface on SW2 – one to each new SVI – and setthe DHCP scope (options) on the Lab Server. Make sure each PC gets the correct corresponding IP address.Make sure to save your packet tracer lab work.
