How to configure DHCP in Cisco IOS Routers

DHCP is a dynamic host configuration protocol. We don't need to manually set IP address to the hosts in the local network by configuring DHCP in the routers. The router will automatically set by itself. The example of how to configure DHCP in Cisco IOS Router is shown in the below with the picture together. I hope this example will be benefit for brothers and sisters who are learning Cisco Networking.

How to configure RIP in Cisco Routers

RIP (Routing Information Protocol) is the oldest distance vector routing protocol. The maximum number of hop count is 15 and the hop count number 16 is defined as infinite distance. The converged time is slow if compared with other routing protocols such as EIGRP, OSPF and IS-IS. There are two versions in RIP: version 1 and version 2.

 
RIP V1

RIP v1 uses FLSM (fixed length subnet masking) and does not support VLSM(variable length subnet masking). Using FLSM causes IP wastes.

 

FLSM Examples,

192.168.1.0 /24

192.168.2.0 /24



RIP V2

RIP V2 supports VLSM (variable length subnet masking). If there are different amount of hosts in an organization, we should use RIP v2.

 

For example,

HR Department : 20 hosts

Engineering Department: 50 hosts

IT department: 10 hosts

Sales department: 30 hosts

 

The following is the sample configuration of RIP in Cisco Routers.

Securing Cisco Networking Devices

We should set passwords in Cisco networking devices so that non authorized people can't access easily. The followings are the ways to set passwords in Cisco networking devices by CLI.

(Note : Most of Cisco Networking Devices are needed to be configured by CLI)


*** Console Password ***

enable (en)

configure terminal (config t)

line console 0

password console123 (type secured password)

 

*** Enable Password ***

enable (en)

configure terminal (config t)

enable password enable123 (type secured password)

 
 
*** Enable Secret ***

enable (en)

configure terminal (config t)

enable secret secret123 (type secured password)

 

*** VTY Password ***

enable (en)

configure terminal (config t)

line vty 0 15

password vty123 (type secured password)

 

*** To go back enable mode ***

Why should we use private or business emails?
There are many public email providers such as Google, Yahoo, and Hotmail. We can use those public emails by free of charge. But using public emails is not as secured as private emails. Why? Millions of users are using public emails by free of charge. So, each user can't be administrated on the server. By using private emails, you will get the following benefits:

 
1. Security
We can also filter the spam mails in Public Emails. But not 100%. We can filter the spam mails in the server by using private emails. And, we can also use private encryption. So, more secured.


2. Email Name 
We can't choose the email names what we want by using public email services. For example, we can't get [email protected] or [email protected]. By using private emails, you can get the email names what you want. For example, [email protected] or [email protected].


3. Impression of Customers
Using public emails is not suitable in the businesses. Using private emails is the best habit to get impression of the customers.

 
How can we get private / business Emails?


1. Google provides Google Suite for private email service.

2. Microsoft provides Office 365 for private email service and applications.

3. Setting up private / own exchange servers. It is not suitable for small business as the cost is high.

4. Web Mail.
