Selection of Router & Cabling a Route

When Router used – LAN with WAN connect – to connect networks of different IP

Different interface of Router – AUI /S0/S1/AUX – console / BRI etc.

Cables used in different interfaces/purpose of interfaces

WAN interface cable – EIA/TIA – 232/449/530 – V.35 – X.21

Different CISCO series – modular/fixed – 10mbps/100 etc

Straight through between DTE & DCE

Different modes of operation & basic commands

Internal Components:

ROM – POST – BSL – ROM-MONITOR PRG – MINIIOS

Different interface of Router – AUI /S0/S1/AUX – console / BRI etc.

DRAM -Running Config

NVRAM – Startup Config

Flash MEM – IOS

Different Modes:

ROM Monitor – Reboot Mode – Setup – Exec Model

Exec Mode

User -Privilege – Global – Sub-configuration mode

Syntax/command to switch between modes

Assigning IP address for -E0-S0-S1

Enabling/disabling – console/privilege / vty password

Mold – command

Show Config / start / run / version / flash

Basic commands practice

Changing between modes – (user-privilege- Global-etc)

IP address configuration-E0-S0-S1

Password – enabling – encrypting it

Practice – motd – show commands – editing commands

Assigning host name (for Router)

Advanced Commands

Register value – X2102 – boot field value/purpose ROM monitor made – password breaking 8th/6th/13th bit of register value importance

Boot system flash/network/ROM – config-register (Changing register value) – etc command purpose Booting sequence – Backup & Recovery – CDP

Practice an above commands as well as following

Telnet – [ctrl+shift+6]x – disconnect – sh users /Sessions

Clear lines resume – [hostname resolving in telnet domain Enabling/disabling etc - no practical for this alone]

IP Routing

IP Routing, Static Routing & Default Routing

IP routing – static routing – default- dynamic routing

Providing clock rate to up the link after identifying DCE by “Sh controllers” command

Commands/syntax – Static/default routing

Static Routing & Default Routing

Practical-session for Static & default routing

Dynamic Routing and RIP

Dynamic Routing – IGP & EGP

IGP – RIP-OSPF – EGRP – EIGRP

Classes of Routing Protocol – Distance vector – Link State – Balanced hybrid

Role of Routing Protocol – builds/updates/selects & Routes the packet

Soluting for Routing loops – Max. loop count – split horizon – Route poison Reverse – Hold down Timer

Features of RIP – distance vector algorithm – RIP V1/V2 – load sharing – metric (depends – loop count)

Metric value depends – loop count – Ticks – delay – Reliability – cost – MTU – Bandwidth

Command – Router RIP Network

Sh IP route

Timer value for RIP– Update/Invalid/ hold down/flush Timer
