CCNAv2 Completed Packet Tracer 10.1.3.3

Greetings, and welcome to Seeseenayy.

Packet Tracer Details: This packet tracer asks us to configure basic DHCP on a router, giving us the option to configure DHCP from the routers, as well as relays and other.

Below you will find a download of the completed packet tracer file. It is recommended that you read the tutorial or so.

Completed Packet Tracer 10.1.3.3 Configuring DHCPv4 using Cisco

Alternatively, you may use the commands from the tutorial.

Tutorial / Walk-through 

First, we need to configure our DHCP pools, as per the steps below:

Part 1: Configure a Router as a DHCP Server
Step 1: Configure the excluded IPv4 addresses.
Configure R2 to exclude the first 10 addresses from the R1 and R3 LANs. All other addresses should be available in the DHCP address pool.

Step 2:     Create a DHCP pool on R2 for the R1 LAN.
a.    Create a DHCP pool named R1-LAN (case-sensitive).
b.    Configure the DHCP pool to include the network address, the default gateway, and the IP address of the DNS server.

Step 3:     Create a DHCP pool on R2 for the R3 LAN.
a.    Create a DHCP pool named R3-LAN (case-sensitive).
b.    Configure the DHCP pool to include the network address, the default gateway, and the IP address of the DNS server.

Part 2: Configure DHCP Relay 
Step 1: Configure R1 and R3 as a DHCP relay agent. 
Step 2: Set PC1 and PC2 to receive IP addressing information from DHCP.

R1 Configuration
R1>en
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#int g0/0
R1(config-if)#ip helper-address 10.1.1.2
R1(config-if)#exit

R1(config)#

R2 Configuration
R2>en
R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#ip dhcp excluded-address 192.168.10.1 192.168.10.10
R2(config)#ip dhcp excluded-address 192.168.30.1 192.168.30.10
R2(config)#ip dhcp pool R1-LAN
R2(dhcp-config)#network 192.168.10.0 255.255.255.0
R2(dhcp-config)#default-router 192.168.10.1
R2(dhcp-config)#dns-server 192.168.20.254
R2(dhcp-config)#exit
R2(config)#ip dhcp pool R3-LAN
R2(dhcp-config)#network 192.168.30.0 255.255.255.0
R2(dhcp-config)#default-router 192.168.30.1
R2(dhcp-config)#dns-server 192.168.20.254


R3 Configuration
R3>en
R3#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R3(config)#int g0/0
R3(config-if)#ip helper-address 10.2.2.2

R3(config-if)#

Assign DHCP addresses for the PCs (PC1 & PC2).
R2(config)#
R2(config)#int g0/1
R2(config-if)#ip add dhcp
R2(config-if)#ex

R2(config)#

After this we can check from R2 if 'show ip dhcp binding'. You should be at 100/100 (100%).
R2#show ip dhcp binding
IP address Client-ID/ Lease expiration Type
Hardware address
192.168.10.11 0002.4AA5.1470 -- Automatic
192.168.30.11 0004.9A97.2535 -- Automatic
