    CCNAv2 Completed Packet Tracer 10.3.1.2

    Greetings, and welcome to Seeseenayy.

    Packet Tracer Details: In this culminating activity, you will configure VLANs, trunks, DHCP Easy IP, DHCP relay agents, and configure a router as a DHCP client. Though, it gives me a LOT of trouble...

    Below you will find a download of the completed packet tracer file. It is recommended that you read the tutorial. I SOLVED THE DHCP THINGY! TY INTERNETS!

    Alternatively, you may use the commands from the tutorial.

    Tutorial / Walk-through 
    In this culminating activity, you will configure VLANs, trunks, DHCP Easy 
    IP, DHCP relay agents, and configure a router as a DHCP client.
    Our first steps, using the table above, is to create VLANs on S2 and 
    assign them to the appropriate interfaces/ports. We need to configure them 
    for trunking, non-trunk ports as Access Ports, and other as needed.
    S2>en
    S2#conf t
    Enter configuration commands, one per line.  End with CNTL/Z.
    S2(config)#vlan 10
    S2(config-vlan)#name Sales
    S2(config-vlan)#vlan 20
    S2(config-vlan)#name Production
    S2(config-vlan)#vlan 30
    S2(config-vlan)#name Marketing
    S2(config-vlan)#vlan 40
    S2(config-vlan)#name HR
    S2(config-vlan)#exit
    S2(config)#int range fa0/5-9
    S2(config-if-range)#switchport access vlan 10
    S2(config-if-range)#int range f0/10-14
    S2(config-if-range)#switchport access vlan 20
    S2(config-if-range)#int range f0/15-19
    S2(config-if-range)#switchport access vlan 30
    S2(config-if-range)#int range f0/20-24
    S2(config-if-range)#switchport access vlan 40
    S2(config-if-range)#ex
    S2(config)#int range fa0/5-9
    S2(config-if-range)#switchport mode access
    S2(config-if-range)#ex
    S2(config)#int range f0/10-14
    S2(config-if-range)#switchport mode access
    S2(config-if-range)#ex
    S2(config)#int range f0/15-19
    S2(config-if-range)#switchport mode access
    S2(config-if-range)#ex
    S2(config)#int range f0/20-24
    S2(config-if-range)#switchport mode access
    S2(config-if-range)#ex
    S2(config)#int range fa0/1-4
    S2(config-if-range)#switchport mode trunk
    S2(config-if-range)#ex
    S2(config)#int range fa0/1-4
    S2(config-if-range)#switchport mode trunk
    S2(config-if-range)#int range fa0/5-24, g0/1-2
    S2(config-if-range)#switchport mode access

    So, as of current, we've established:
    - VLANs on S2 with the appropriate name.
    - S2 ports for trunking.
    - S2's non-trunk ports on S2 as access-ports.

    To further configure VLANs, we're going to be editing our router.
    Why? Well, we need to configure R1 to route between our VLANs, as well as  creating a DHCP server for the VLANs attached to S2.

    R1>en
    R1#conf t
    Enter configuration commands, one per line.  End with CNTL/Z.
    R1(config)#int g0/0.10
    R1(config-subif)#encapsulation dot1Q 10
    R1(config-subif)#ip add 172.31.10.1 255.255.255.224
    R1(config-subif)#int g0/0.20
    R1(config-subif)#encapsulation dot1Q 20
    R1(config-subif)#ip add 172.31.20.1 255.255.255.240
    R1(config-subif)#int g0/0.30
    R1(config-subif)#encapsulation dot1Q 30
    R1(config-subif)#ip add 172.31.30.1 255.255.255.128
    R1(config-subif)#int g0/0.40
    R1(config-subif)#encapsulation dot1Q 40
    R1(config-subif)#ip add 172.31.40.1 255.255.255.192
    R1(config-subif)#ex
    R1(config)#int g0/0
    R1(config-if)#no sh
    R1(config)#int g0/1
    R1(config-if)#ip add dhcp
    R1(config-if)#no sh

    So this essentially configured our VLANs and otherwise needed information 

    to make this network function. The next instructions were to configure the devices so that the DNS server would work. 
    Note that G0/1 is going to obtain an address via DHCP-- which is fine-- 

    but many missed this, which caused the network to not work. We have to configure R1 to act as a DHCP server for VLANs attached to S2, to which we must assign a name for each VLAN and the respective addresses, as well as providing the Default Gateway address, as well as preventing the first 10 addresses from being assigned.

    So what we're going to do is start off with the blocking of the 10 assigned addresses, so enter the following:
    R1(config-if)#ex
    R1(config)#ip dhcp excluded-address 172.31.10.1 172.31.10.10

    Now, we can go ahead and create our DHCP pools, since the addressing ranges have been blocked properly, as well as creating the proper addressing pools for the DHCP part.

    R1(dhcp-config)#network 172.31.10.0 255.255.255.224
    R1(dhcp-config)#default-router 172.31.10.1
    R1(dhcp-config)#dns-server 209.165.201.14
    R1(dhcp-config)#ip dhcp excluded-address 172.31.20.1 172.31.20.10

    So, in red is the network addressing pool we had assigned.
    The blue is essentially how we assign default gateways in DHCP.
    The orange is how we tell what IP that houses the DNS service.
    The purple is how we exclude addresses in DHCP.
    Also, when you enter the purple command, it will auto-boot you from that 

    configuration, which is fine, because now, we need to repeat this process 

    for the remainder of the VLANs.

    R1(config)#ip dhcp pool VLAN_20
    R1(dhcp-config)#network 172.31.20.0 255.255.255.240
    R1(dhcp-config)#default-router 172.31.20.1
    R1(dhcp-config)#dns-server 209.165.201.14
    R1(dhcp-config)#ip dhcp excluded-address 172.31.30.1 172.31.30.10

    Do you sort of see how the repition is here? Specifically, the excluded-

    address command: You exclude the range of the next VLAN over to 

    (obviously) prevent any connection issues-- an IP that belongs to VLAN 20 

    won't work on VLAN 10, and so forth.

    R1(config)#ip dhcp pool VLAN_30
    R1(dhcp-config)#network 172.31.30.0 255.255.255.128
    R1(dhcp-config)#default-router 172.31.30.1
    R1(dhcp-config)#dns-server 209.165.201.14
    R1(dhcp-config)#ip dhcp excluded-address 172.31.40.1 172.31.40.10

    R1(config)#ip dhcp pool VLAN_40
    R1(dhcp-config)#network 172.31.40.0 255.255.255.192
    R1(dhcp-config)#default-router 172.31.40.1
    R1(dhcp-config)#dns-server 209.165.201.14

    Note that on VLAN 40 we don't nessessarily need an exclusion command as 

    nothing else exists (we don't have any further VLAN configurations, 

    therefore we don't need to narrow the range).

    NOTE: MANY PEOPLE HAVE ISSUES WITH THIS AND GET STUCK AT 84/100 OR 80/100.

    YOU HAVE TO GO INTO SWITCH 1 (S1) AND DO AS FOLLOWS.
    S1>en
    S1#conf t
    Enter configuration commands, one per line. End with CNTL/Z.
    S1(config)#vlan 10
    S1(config-vlan)#name VLAN_10
    S1(config-vlan)#ex
    S1(config)#vlan 20
    S1(config-vlan)#name VLAN_20
    S1(config-vlan)#ex
    S1(config)#vlan 30
    S1(config-vlan)#name VLAN_30
    S1(config-vlan)#ex
    S1(config)#vlan 40
    S1(config-vlan)#name VLAN_40

    S1(config-vlan)#ex
