1.1.4
4 major phases tot the boot up process:
1. Performing the POST: Power on Self‐Test
2. Loading the bootstrap program: Locate Cisco IOS and load it into RAM
3. Locating and loading the Cisco IOS software: from flash memory or TFTP otherwise empty
IOS from ROM
4. Locating and loading the start‐up configuration file or entering setup mode
Show version: command can be used to help verify and troubleshoot some of the basic hardware
and software components of the router.
Show running‐config
1.1.6
Routers operate at Layers 1, 2 and 3
1.2.2 Basic router configuration:
Router(config)#hostname R1
Router(config)# enable secret password
Router(config)# line console 0
Router(config‐line)#password password
Router(config‐line)#login
Router(config)#line vty 0 4
Router(config‐line)#password password
Router(config‐line)#login
Router(config)#banner motd # message #
Router(config)# interface type number
Router(config‐if)# ip address address mask
Router(config‐if)#description description
Router(config‐if)#no shutdown
Router#copy running‐config startup‐config
Router#show running‐config
Router#show ip route
Router#Show ip interface brief
Router#show interfaces
, 1.3.1 introducing the routing table
A routing table is a data file in RAM that is used to store route information about directly connected
and remote networks.
Directly connected routes: routes in the same network
Static routes: are routes to networks that has manually configerd routes.
Dynamic routing protocol: automated learned routes to remote networks
Router# show ip route
C:\route print
1.3.3 static routing
When to use static routes:
1. A network consists of only a few routers
2. A network is connected to the internet only through a single isp.
3. A large network is configured in a hub‐and‐spoke topology
1.3.4 Dunamic routing
Ip routing protocols:
RIP(routing information protocol)
IGRP(interior gateway routing protocol)
EIGRP(Enhanced interior gateway routing protocol)
OSPF(Open Shortest Path First)
IS‐IS(Intermediate system‐to‐intermediate system)
BGP(border gateway protocol)
1.4.2 Best path and Metric
Hop count: is the number of routers (RIP)
Bandwidth: determines the best path based on bandwith(ospf)
1.4.3 Equel cost Load Balancing
EIGRP
