Different Modes:

ROM Monitor – Reboot Mode – Setup – Exec Model

Exec Mode

User -Privilege – Global – Sub-configuration mode

Syntax/command to switch between modes

Enabling/disabling – console/privilege / vty password

Mold – command

Show Config / start / run / version / flash

Basic commands practice

IP address configuration-E0-S0-S1

Password – enabling – encrypting it

Practice – motd – show commands – editing commands

IP Routing

IP Routing, Static Routing & Default Routing

IP routing – static routing – default- dynamic routing

Commands/syntax – Static/default routing

Static Routing & Default Routing

Practical-session for Static & default routing

Dynamic Routing and RIP

Dynamic Routing – IGP & EGP


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
