Example about Directly connected :
cast :
Robert
Sarah
Aamy
## Robert met agirle in the university
and ask her : Hello,Whats your name?
1- the girl answered : My name is Sarah .
And Sarah asked him , whats your name ? he said My name is Robert ।
Now Sarah and Robert have been directly connected with each other .
## then he went to another girl :
and asked her Hello, whats your name?
2- the girl answered My name is Aamy .
And Aamy asked him , whats your name ? he said My name is Robert |
Now Aamy and Robert have been directly connected with each other .
$$ Now Robert has known Sarah and Aamy and directly connected with both of them |
But Sarah & Aamy didnt know each other .
## while Robert walking with Sarah he met Aamy and :
Robert Said : Sarah! this is Aamy
Sarah Said : Oh! Hello Aamy
Aamy Said : Hello Sarah
Now Sarah & Aamy connected by robert by sharing Robert's friend Aamy to Sarah and sharing him friend Sarah to Aamy but we want to say here in Routing protocol friends mean
( neighbors ) its mean we are using Routing protocols for disseminating information that enables them to select routes between any two nodes on a computer network .
as we can see in routing table
first we want to know somthing about Routing Table .
we need to know some codes like :
C - connected, S - static, I - IGRP, R - RIP, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area .
C - connected : this mean my router directly connected for your router.
S - static route : this mean by Administratore.
I - IGRP : An interior gateway protocol (Routing protocol)
R - RIP : Routing Information Protocol (Routing protocol)
B - BGP : Border Gateway Protocol (Routing protocol)
D - EIGRP : Enhanced Interior Gateway Routing Protocol (Routing protocol - Cisco proprietary)
O - OSPF : Open Shortest Path First (Routing protocol)
example about how to connect between routers and show routing Table ..etc
go to R1 then press on it to configure it by console cable then enter to it and type :
R1>enable ( User mode )
R1# ( Privilege mode )
R1#configure terminal ( Type configure terminal to go to Global configuration mode )
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)# ( Global configuration mode )
R1(config)#interface e0/0 ( Type your interface )
R1(config-if)#ip address 192.168.30.10 255.255.255.0 ( Type your ip for this interface )
R1(config-if)#no shutdown ( Enable this interface )
R1(config-if)# ( Press on CNTL/Z to end and go to previlige mode )

## Don't forget to type :
R1#copy running-config startup-config ( to save your configuration to NVram )
Destination filename [startup-config]? Building configuration... [OK]
Now we want to show routing table by type :
R1#show ip route
its mean R1 and R2 has been directly connected .
Now we will go to R2 to configure it by type :
R2>enable
R2r#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#interface e1/0

Notes :
1- sometimes type something wrong and appear for you like this message its mean Domain server and your router thought you are having domain lookup called for example (Ki) which i typed wrong
in this case if you want to disable Domain server enter to ( Global configuration mode ) and type
R1(config)#no ip domain lookup
2- if you want to troubleshooting your interfaces if it up or down u should type :
Router#show ip interface brief
рей-if you want to verifying Mac Address on Ethernet interfaces you can type :
Router#show interfaces f0/0
3- its found two types of serial cables ( DCE & DTE ) if you want to know are this interfaces using ( DCE or DTE ) you should type for example :
Router#show controllers s0/0 (s0/0 its mean for any interface you want to configure it)
after that you should type on DCE interface cable you should type for example :
Router(config-if)#clock rate 64000
