Intermediate CCNA Training (Module #4) – Router Fundamentals:
CCNA (Cisco Certified Network Administrator) is a certificate of competence in networking which validates the ability of a professional in understanding, installation, configuration, operation and trouble shooting of medium sized switched and routed networks. The certification is provided by CISCO, one of the leading IT companies in the world.
About CCNA Training
CCNA Training is a comprehensive training programme that covers all the concepts in CCNA Certification. It helps the the learner understand various concepts on router configuration, protocols, it s management and service management. The course has over 115 lectures and 21 hours of high definition video intended to provide in-depth knowledge and practical training in all aspects of CCNA certification.
Line Configuration Theory:
The introductory part of the course deals with the concept of line configuration. It refers to the system in which two or more devices are connected to a link. The physical communication path that enables data transfer from one device to another is called the link. Without it, no communication can happen between two devices. The section also deals with the two possible line configurations-Point-to-Point line configuration & Multi Point line configuration. When more than two specific devices share a line, it is called Multi-Point.
Topology-– The section also covers the topology of networking- refers to how endpoints in the network are connected. There are different types of topologies- mesh topology, star topology, tree (Hierarchical) topology, bus topology, ring topology and cellular topology. Ring and mesh are for peer-to-peer, star and tree for client server, bus topology applicable for both.
Types of Networks:
Different types of networks are covered in this section- classification based on size and purpose, geographical area covered and number of computers networked. Personal Area Network (PAN), Local Area Network (LAN), Metropolitan Area Network, Wide Area Network (WAN). Networks are normally for general purpose-used for many purposes including sending files to printer or access internet. Some networks are meant for a particular purpose- Storage Area Network (SAN), Enterprise Private Network (EPN) and Virtual Private Network.
Transmission mode –is based on number of bits transferred simultaneously and synchronization between transmitter and receiver. Types – Simplex, Half Duplex, Full Duplex.
OSI Model:
Open System Interconnection was developed by International Organisation for Standardisation (ISO). It defines how data is transmitted over a network. Data transmission is broken into seven steps- physical layer (address physical characteristics of network- devices, cables, connectors etc, application layer (the layer end user interacts with- software- such as Internet Explorer, FireFox etc, presentation layer (concerned with presentation of data), session layer (allows ongoing communication between two devices or entities in a network, transport layer (responsible for transmission of data), network layer , data link layer (responsible for setting packet size, transmission and delivery)..
Ethernet and packet information:
Ethernet- is a widely used LAN technology- it’s a link layer protocol that specifies how networked devices can format data for transmission and how to put it out on the network connection. It connects with Layer 1 (Physical Layer) and Layer 2 (Data Link Layer) on the OSI model. It reduces latency time on packet delivery. -CISCO 3 layer model- Core Layer- fast and responsible transportation data, CISCO Switches 7000, 7200, 75000, 12000 (WAN), Catalyst switches- 6000,5000, 4000 (LAN use), Distribution Layer-is responsible for routing- packet filtering (firewalling), QoS, Access Layer Aggregation Point, Control Broadcast and Multicast, Application Gateways. Access Layers- contains devices that allow workgroups/users to utilize the services provided by distribution and core layers.
Ethernet and wiring standard– two standards-T568A Wiring and T568B wiring, WiFI, Summary of topics covered in the section.
Objective and introduction to IP:
Introduction to Internet Protocol (IP). IP specifies which data is sent between computers on a network. Each computer or host has one IP address that identifies it on the net. IP delivers data while TCP reassemble it in right order.
IP Stack: TCP/IP Introduction:
TCP/IP is the set of protocols that determine how data is transmitted through the network (internet). Like the OSI Model, the TCP/IP has a set of corresponding layers which are collectively called the IP Stack- Application (eg. NFS, NIS, DNS, LDAP, telnet, ftp, rlogin, rsh, rcp, RIP, RDISC, SNMP), Transport (TCP, UDP, SCTP),Internet (IPv4. IPv6, ARP, ICMP), Data Link (PPP, IEEE, 802.2), physical network (Ethernet (IEEE 802.3), Token Ring, RS-232, FDDI, others).
- TCP IP Stack-Transport Layer-ensures packets arrive in sequence and without error, swaps acknowledge of data receipt , retransmission of lost packets-end-to-end communication- TCP (Transmission Control Protocol)- User Datagram Protocol (UDP), Stream Control Transmission Protocol (SCTP) .
- Network Interface Layer-first layer of four layer TCP/IP model- defines how data is physically sent through networks, – coaxial cable, optical fiber, copper wire etc. Protocols- Ethernet, Token, Ring, FDDI, X.25. Frame Relay.
IP Addressing:
IP –to uniquely identify a device on the network-32 bits binary-,network option – host option-subnet mask. Network Masks.
- IP Address Components– Octets-conversion of binary to decimal, octet conversion, dotted decimal format, eg 192.168.123.132 or 32 bit binary equivalent- division into four parts of eight bits.
- IP Subnetting: Understanding IP subnetting-creation of multiple logical networks- interconnecting subnetworks, IP addresses, Subnet mask used by TCP/IP protocol to know whether a host is on local subnet or remote network.
- Variable Length Subnet Masking (VLSM)– process of dividing IP network into subnets of variable sizes without wasting IP addresses. In Fixed Length Subnet mask (FLSM)-all subnets have same number hosts- lead to inefficiencies. VLSM- eg excel sheet .
- Direct Broadcast address– valid host- to implement remote administration task- backups, wake-on-LAN-broadcast packets to host in specified destination subnet. IP Directed broadcast packet is – aims to flood target subnet but not broadcasting to entire network. Implementation of IP Broadcast- How to find the valid host…summary of topics in IP Addressing.
- Routers– most intelligent compared to hubs , switches, directs traffic to the appropriate computers in the network. Dynamic Host Configuration Protocol, NAT (Network Address Translation). Router types, vendors and theory. Routers capture data from a broadband connection through a modem and pass it on to the computer. Routers operate at physical, data link and network layer of OSI model.
- HUB Theory and Switches: Hubs, Switches , routers- helps in connecting one or more computers on a network- Hubs- simple –port-to-port communication. Every computer connected to hub sees everything other computes see on the hub- Switches- enable targeting of messages to concerned ports , not all ports-makes network faster.
