2. INTRODUCTION
 CCNA stands for Cisco
Certified Network
Associate
 It gives the information
about networking ,its types
and its application .
 Networking is very
important as it provides
communication.
 It is also very useful as it
helps in resource sharing.
 Thus , overall it is a cost
saving technique.

3. TYPES OF NETWORKING
 LAN – It stands for local area network. Eg: network within
a campus .
 MAN – It stands for metropolitan area network. Eg:
network connecting various cities.
 WAN – It stands for wide area network. Eg : internet on a
whole world.

4. Networking Devices
LAN card
BRIDGE
HUB
SWITCH
ROUTER

5. Subnetting and Supernetting
About subnetting & Supernetting
In subnetting, a network is divided into several smaller subnetwork with each
subnetwork(or subnet) having its own subnetwork address.
In supernetting, an organization can combine several class C addresses to create a
larger range of addresses(supernetwork).
SUBNETTING
Class A, B, C in IP addressing are designed with two levels of hierarchy.
The organization has two-level hierarchical addressing, but it cannot have more
than one physical network./ The host cannot be organized into groups, and all of the
hosts are at the same level./ The organization has one network with many hosts.
One solution to this problem is subnetting, the further division of a network into
smaller networks called subnetworks.

6. EXAMPLE OF SUBNETTING
( Example / Class A)
An organization with a class A address at least 1,000 subnetworks. Find the
subnet mask and
configuration of each subnetwork.
(Solution)
1. There is a need for at least 1,000 subnetworks.(we need at least 1,002
subnetworks to allow for the all-1s and all-0s subnetids)
2. This means that the minimum number of bits to be allocated for
subnetting should be 10, (29 < 1,002 < 210).
3. 14 bits are left to define the hostids. Subnet mask (11000000 = 192).

8. Range of addresses

9. Subnetworks in example

10. Classless Interdomain
Routing(CIDR)
Supernetting means assigning a set of class C addresses to an organization that needs more
than 254 host addresses.
However , when these class C addresses are entered into the routing table, each occupies
one entry in the routing table./ 256 entries in the routing table.
The classless interdomain routing(CIDR) technique is devised to reduce the number
of routing table entries.
In this technique, instead of entering each single class C address with its corresponding
default mask(255.255.255.0), the router can use the supernet mask and the
lowest network address in the group.

11. CIDR

12. Hubs vs. switches
Hubs – less expensive,
used in a very small LAN
where low throughput is
OK
Switches – segments
collision domains,
interconnects network
segments, more
expensive, but
performance makes it
cost effective.

13. It is a layer 3 or network
layer device.
In this there is no
broadcast.
It is WAN technology
device.
It is useful to connect
different networks.
Packet filtering & it finds
the best path selection.
ROUTERS

14. Router Configuration
 Router always has two configurations:
 Running configuration
 In RAM, determines how the router is currently operating
 Is modified using the configure command
 To see it: show running-config
 Startup confguration
 In NVRAM, determines how the router will operate after next
reload
 Is modified using the copy command
 To see it: show startup-config

15. Router Access Modes
 User EXEC mode - limited examination of router
– Router>
 Privileged EXEC mode - detailed examination of
router, debugging, testing, file manipulation
– Router#
 ROM Monitor - useful for password recovery & new
IOS upload session
 Setup Mode – available when router has no startup-
config file

16. Logging Into The Router
 Connect router to console port or telnet to router
– router>
– router>enable
– password
– router#
– router#?
 Configuring the router
– Terminal (entering the commands directly)
– router# configure terminal
– router(config)#
USER MODE
PROMPT
PRIVILEDGED MODE
PROMPT

17. Deleting Your router’s
Configuration
To delete your router’s configuration
 Router#erase startup-config
OR
 Router#write erase
 Router#reload
 Router will startup again, but in setup mode, since
startup-config file does not exists

18. ROUTING
Routing is the exchange
of routes between
different networks .
There are three types of
routing:
1. Default routing
2. Static routing
3. Dynamic routing

19.  A routing protocol is the communication used between
routers.
 A routing protocol allows one router to share information
with other routers.
 The information a router gets from another router, using a
routing protocol, is used to build & maintain a routing
table.
Examples of routing protocols:
1. RIP [ROUTING INFORMATION PROTOCOL]
2. EIGRP[ENHANCED INTERIOR GATEWAY ROUTING
PROTOCOL]
3. OSPF[OPEN SHORTEST PATH FIRST]
DYNAMIC ROUTING

20. Routing Information Protocol
(RIP)
• RIP is a distance vector routing protocol
• Hop count is used as the metric for path selection
• If the hop count is greater than 15, the packet will be
discarded
• By default, routing updates are broadcast every 30
seconds
• RIP has evolved over the years from a Classful Routing
Protocol, RIP Version 1 (RIP v1), to a Classless Routing
Protocol, RIP Version 2 (RIP v2).
• Configuring RIP
Router(config)#router rip

21. Enhanced Interior Gateway
Routing Protocol (EIGRP)
• Really just an enhanced version of IGRP
• A Cisco proprietary routing protocol
• Called a hybrid protocol, but really just an advanced distance
vector protocol.
• Fast convergence
• Variable length subnet masks
• Partial updates - only when the metric for a route changes
(bounded updates)
• Multiple network layer support - IP, IPX, and AppleTalk
• A router running EIGRP stores all its neighbor’s routing tables so
that it can quickly adapt or alternate routes.

22. Features of EIGRP
 Classless Routing Protocol (VLSM, CIDR)
 Faster convergence times and improved scalability
 Multiprotocol support: TCP/IP, IPX/SPX, Appletalk
– There is no IPX/SPX or Appletalk in CCNA or CCNP
 Rapid Convergence and Better handling of routing loops – (DUAL)
 Efficient Use of Bandwidth
– Partial, bounded updates: Incremental updates only to the routers
that need them.
– Minimal bandwidth consumption: Hello packets and by default
uses no more that 50% of link’s bandwidth EIGRP packets.
 PDM (Protocol Dependent Module)
– Keeps EIGRP modular
– Different PDMs can be added to EIGRP as new routed protocols are
enhanced or developed: IPv4, IPv6, IPX, and AppleTalk

23. OSPF
 Open Shortest Path First
 Dynamic IGP (Interior
Gateway Protocol)
 Use within your own
network
 Link state algorithm

24. WhaT IS ACL?
Routers provide basic traffic
filtering capabilities, such as
blocking Internet traffic, with
access control lists (ACLs).
An ACL is a sequential list of permit
or deny statements that apply to
addresses or upper-layer protocols.
This module will introduce
standard and extended ACLs as a
means to control network traffic,
and how ACLs are used as part of a
security solution.

25. VLAN
• VLAN stands for virtual
local area network.
• Devices on different
VLAN must have a router to
communicate with each
other.
• If devices are on the
same VLAN, then they can
communicate through a
switch.

26. INTER VLAN ROUTING
 A VLAN is a broadcast domain and
unique ip subnet
 Switches operate at layer2 (Data link
Layer)
 VLANS cannot communicate without L3
(Network Layer)
 The L3 communication is called inter-
vlan routing
 Inter-vlan routing is a process of
forwarding network traffic from one vlan
to another using a router
 The Subnets of your network facilitate
the routing process.
 Router interfaces can be connected to
separate vlans.
 Devices on vlans send traffic through the
router(L3) to other vlans.

27. How to configure EIGRP with RIP on same
network
In this article we will discuss how can two routing protocols exist in same network?
We have discussed basic of both EIGRP and RIP in our previous article. Now we will go
in more depth by including both RIP and EIGRP in same network.
