The document provides an overview of several networking topics including EIGRP, NAT, protocols like RIP, OSPF, and DHCP. It discusses what EIGRP and RIP are, how NAT works and the different types (static, dynamic, PAT). It also mentions extra protocols like OSPF, ACLs, and how devices like switches, routers, PCs are used. Keywords discussed include redistribute, password, do wr, and configure mail.

3. Eigrp
• Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced
distance-vector routing protocol that is used on a computer network
for automating routing decisions and configuration. The protocol was
designed by Cisco Systems as a proprietary protocol, available only on
Cisco routers.
• It is a distance vector protocol

4. Unified configuration(ipv4 vs ipv6)
Eigrp ipv4
Int fa0/0
Ip bandwidth eigrp 1
No shut
Router eigrp 1
Network 0.0.0.0 0.0.0.0
Eigrp ipv6
Int fa0/0
Ipv6 enable
Ipv6 eigrp 1
Ipv6 bandwidth-percent eigrp 1
No shut
Ipv6 router eigrp 1
Eigrp router id 10.1.1.1
No shut

5. Rip
• The Routing Information Protocol (RIP) is one of the oldest distance-
vector routing protocols which employ the hop count as
a routing metric.
• RIP prevents routing loops by implementing a limit on the number of
hops allowed in a path from source to destination.

6. Types
• Version 1:First generation legacy protocol
• Version 2:Simple distance vector routing protocol

7. Nat
• Nat is a process used to translate network address.
• Nat’s primary use is to conserve ipv4 address
• Nat is usually implemented at border network devices such as firewall
or routers
• Nat allows the network to use private addresses internally, only
translating to public addresses when needed.

8. Types
•Static
•Dynamic
•Pat

9. Static nat
One private = one public
Internet
203.31.218.208
203.31.218.209

10. Dynamic nat
Internet
203.31.218.208
203.31.218.209
One private = many public

12. DHCP
• DHCP =dynamic host configuration protocol
• From 1993
• An extension of bootp, very similar to DHCP.
• Clients should require no manual configuration by user to connect to
the network.
• Automatic configuration-
⒈ ip address
⒉Subnet mask.

13. Extra protocol
•Ospf
•Rip
•Acl
•DHCP

14. Ospf
• Open Shortest Path First (OSPF) is a routing protocol for Internet
Protocol (IP) networks.
• It uses a link state routing (LSR) algorithm and falls into the group of
interior gateway protocols (IGPs), operating within a single
autonomous system (AS).
• It is defined as OSPF Version 2 in RFC 2328 (1998) for IPv4.

15. How it works?
• Use a link state logic
• Divide routers into areas for route optimization and segmentation
• Neighbor discovery
• Neighbor adjacency requirements
• Topology database exchange
• Link stage advertisement

16. Route computation
Before run spf After run spf

17. Acl
• Acl= access control list essentially a list of conditions that categorize
packets

18. Types
• Standard access control list
• Extended access control list
• Named access control list

19. Steps
• Creating the access list
• Placing the access list

20. Devices
Hub switch router pc dns server email server wifi router

21. Keyword
• Redistribute : to connect to protocol between two network
• Password: for security of router
• Do wr :
• Configure mail : for configuring the email server
• Http : hyper text transfer protocol
