This is the complete DHCP configuration guide on Windows server and Cisco router. The article is based on a step by step guide which helps you configure the DHCP server on Windows Server and Cisco routers easily.

Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway. RFCs 2131 and 2132 define DHCP as an Internet Engineering Task Force (IETF) standard based on Bootstrap Protocol (BOOTP), a protocol with which DHCP shares many implementation details. DHCP allows hosts to obtain required TCP/IP configuration information from a DHCP server.

Why we use DHCP in the network? Every device on a TCP/IP-based network must have a unique unicast IP address to access the network and its resources. Without DHCP, IP addresses for new computers or computers that are moved from one subnet to another must be configured manually; IP addresses for computers that are removed from the network must be manually reclaimed. With DHCP, this entire process is automated and managed centrally. The DHCP server maintains a pool of IP addresses and leases an address to any DHCP-enabled client when it starts up on the network. Because the IP addresses are dynamic (leased) rather than static (permanently assigned), addresses no longer in use are automatically returned to the pool for reallocation.

Benefits of DHCP Server.

Reliable IP address configuration. DHCP minimizes configuration errors caused by manual IP address configuration, such as typographical errors, or address conflicts caused by the assignment of an IP address to more than one computer at the same time.

Reduced network administration. DHCP includes the following features to reduce network administration:

• Centralized and automated TCP/IP configuration.
• The ability to define TCP/IP configurations from a central location.
• The ability to assign a full range of additional TCP/IP configuration values by means of DHCP options.
• The efficient handling of IP address changes for clients that must be updated frequently, such as those for portable computers that move to different locations on a wireless network.
• The forwarding of initial DHCP messages by using a DHCP relay agent, which eliminates the need for a DHCP server on every subnet.

Today I’m going to show you, how to configure Routing Information Protocol (RIP) on the Cisco Routers. The RIP is one of the oldest distance-vector routing protocols and work perfectly with IPv4. The next generation of routing information protocol for IPv6 is know as RIPng (RIP next generation). So in this article we are going to test the RIP with IPv4.

It would be good if you have a physical Cisco lab for testing RIP, otherwise you can use GNS3 ,  Cisco Packet Tracer or equivalent network simulator software.  Here I’m using packet tracer and the Cisco RIP  routing lab I have created is downloadable from the below link. Just download and configure the basic routing with the IP addresses which assigned for each router interfaces. It help your to practice some basic router commands also. I’m sure you can do it, but in case of requiring some help, read the basic router commands from this post.

Downlaod the non configured Routing RIP Protocol lab that need basic configuration and this one Routing RIP Protocol – CCNA Lab -Ready for RIP Lab for CCNA is configured with basic and essential configuration.

 Configure Routing Information Protocol (RIP)

So let’s start configure routing information protocol in this lab. Go to your lab and open the router 1 (R1) which is the main router connected to ISP router. Do the following command for RIP Routing.

R1>enable
R1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#router rip
R1(config-router)#version 2
R1(config-router)#network 200.100.10.0
R1(config-router)#network 192.168.20.0
R1(config-router)#network 10.10.10.0
R1(config-router)#

After enabling router with enable command then go to privileged mode with configure terminal command. Now with router rip command, enable routing for all routers. The version 2 command, configure routing information protocol with version two. And next set all network id like the above network command. I have set all three network which connect directly to R1.

Now go to router R2 and configure routing protocol the same as router R1. On router 2 you must assign the network ids of all connected network the R2.

R2>enable 
R2#configure terminal 
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#router rip 
R2(config-router)#version 2
R2(config-router)#network 10.10.10.0
R2(config-router)#network 192.168.10.0
R2(config-router)#network 192.168.1.0
R2(config-router)#

For ISP router, just enter the network id 200.100.10.0, because only one network connected to ISP router.

ISP>enable
ISP#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
ISP(config)#router rip
ISP(config-router)#version 2
ISP(config-router)#network 200.100.10.0
ISP(config-router)#

OK, your routing task with RIP is accomplished successfully, now all network devices can communicate with each other without any problem through routing information protocol. Test them with ping command and be sure they must ping correctly. If they are not ping with each other, so your routing has some problem. You should troubleshoot it. Here you can download my completed Routing RIP Lab project which work fine.

If you have any question, just ask me through comments. I will reply you as soon as possible.
