Network Classes

Networking
• Network ID: It is to identify host of the same network or domain. All the host portion are zero.Ex.: 10.0.0.0, 150.50.0.0, 200.200.200.0
• Broadcast ID: It is used to broadcast msg to the host of the same network or domain. All the host portion are 255.Ex.: 10.255.255.255, 120.20.255.255, 200.0.0.255
• Loop back IP: It is self testing IP address.Ex.: 127.0.0.1
• Sub netting• Super netting
5
Network Devices
• Hub: Can not break broadcast &
collision domain.
• Switches: Store MAC address, easily
broadcast & unicast the msg.
• Routers: Active device, can break
broadcast & collision domain. Join two diff. network.

Booting Process of Router

Router Modes
User Mode: Provides basic access to the IOS with limited command availability (basically simple monitoring and troubleshooting commands)
Enable/ Privilege Mode: Provides high-level management access to the IOS, including all commands available at User EXEC mode
Configuration Mode: Allows configuration changes to be made to the device

Routing
Static Routing: We have to configure route
manually. Dynamic Routing: In this routing roots are
configure with the help of protocols. Like DS, RIP(Routing Info Protocol), IRGP(Interior Gateway Routing Protocol), Link state, OSPF, Hybrid, BGP(Border Gateway Protocol).
13
Telnet
It is used to access router from one location to another location.
AMI NGPAMI(config)# line vty 0 15AMI(config)# password sac@123AMI(config)#login
NGP(config)# Telnet 20.0.0.1NGP(config)# give telnet passwordNGP(config)# enable password modeNGP(config)# AMI router
14
Access List
Standard: It contain 1-99 nos.,it used to block all services.
Ex.: (config)# access-list1 permit anyExtended: It contain 100-199 nos.,it used to
block one specific service.Ex.: (config)# deny 200.0.0.1 200.0.0.10
(block 10 computer IP address)
15
Troubleshooting Commands
(config)#debug IP RIP
(config)# trace route dest IP address
(config)# traced
