TRAINING TECHNOLOGY : CCNA
CCNA : CISCO CERTIFIED NETWORK ASSOCIATE
The CCNA certification was the first course and exam in the Cisco certification process, and the precursor to all current Cisco certifications. Cisco is the king of routing, switching, and security, the Microsoft of the internetworking world. The Cisco certifications reach beyond the popular certifications, such as the CompTIA and Microsoft certifications, to provide us an indispensable factor in understanding today’s network— insight into the Cisco world of internetworking. The CCNA program was created to provide a solid introduction not only to the Cisco Internetwork Operating System (IOS) and Cisco hardware, but also to internetworking in general, making it helpful to you in areas that are not exclusively Cisco’s. At this point in the certification process, it’s not unrealistic that network managers—even those without Cisco equipment—require Cisco certification for their job applicants.

Routers :- It is a networking device that connects the different computer networks which are at different geographical locations to forward the data packets along with that network.
• These routers have fixed number of ports.
• For e.g.: 700 , 800,900….. 2500 .Fixed
• These routers have upgrade slots & no. of ports can be increased by adding cards in the slots.
• For e.g.: 2600,2700,2800 …… 12000.

RIP ( Routing Information Protocol) :- * A Standardized Distance Vector Protocol . * It doesn’t determine time , it determine the no. of hopes
Version 1
Supports Classful IP address.
Doesn’t send the subnet mask information.
Doesn’t support any kind of authentication.
Sends updates via broadcast address
( 255.255.255.255).
Version 2
Supports Classless IP address.
Sends the subnet mask information.
It Supports any kind of authentication.
Sends updates via multicast address
( 224.0.0.9) .

o A protocol incorporating the features of both Distance- Vector & Link State routing protocols .
o It uses Diffusing Update Algorithm (DUAL) to determine the best path among all feasible paths.
o It is a Classless protocol & thus supports VLSMs.o It has a maximum hope count of 255 .o It is much like OSPF , builds three separate
tables :- 1. Neighbor table2. Topology table3. Routing table
EIGRP(Enhanced Interior Gateway Routing Protocol )

OSPF (Open Shortest Path First) :-
A standard link state routing protocol , designed to scale efficiently to support larger networks .
It employs a hierarchal network design using areas. It uses Dijkestra Shortest Path Algorithm to
determine the shortest path . OSPF process builds & maintains 3 separate
tables :-1) Neighbor table2) Topology table3) Routing table OSPF has no hopes count limit .

ACL(Access Control List)
Access Control lists can be used for two purpose on Cisco device:
i)To filter traffic
ii)To identify traffic
Access lists are set of rules, organized in a rule table. Each rule in an access-list provides a condition, either permit or deny .When using an access-list to filter traffic, a permit statement is used to “allow” traffic, while a deny statement is used to “block” traffic.

TYPES OF ACLSTANDARD ACL:-
In standard access list we can block or permit particular host as well as whole network.
It forwards filter packets on the basis of source address only.
Types of standard ACL:
1)Number ACL-1 to 99
2)Name ACL
EXTENDED ACL:-
The extended number ACL are more flexible as compare to the standard ACL.
Extended depends upon the source as well as destination address.
Types of extended ACL:
1)Number Acl-100 to 199
2)Name ACl
