- This artice in english
I dette eksempel konfigureres en Cisco 2621XM router fra grunden.
Konfigurationsoversigt
En Cisco 2621XM har to FastEthernet interfaces. FastEthernet 0/0 og FastEthernet 0/1.
- hostnavn konfigurers til Viborg1
- FastEthernet 0/0 konfigures med ip adressen 192.168.22.1 og subnetmasken 255.255.255.0
- FastEthernet 0/1 konfigures med ip adressen 172.16.0.1 og subnetmasken 255.255.0.0
- loopback 0 interfacet som er et virtuelt interface får ip adressen 10.10.10.1 og subnetmasken 255.255.255.255
- RIP version 2 konfigureres til at inkludere alle tre subnet (FastEthernet porte og loopback porten)
Forbind routeren og en PC's COM port med et cisco roolover kabel. Se billedet af et roolover kabel. Start en terminalemulator på PC'en. Jeg vil anbefale terminalemulatoren putty
Start Putty and udfyld konfigurationsbilledet som markeret med de røde ringe i figur 1. (Min COM port er på COM6. Din er måske på en anden. Forsøg dig frem eller se det i Windows enhedshåndtering)
Start routeren og du bør kunne se på Putty at routeren er ved at boote. Når routeren er bootet er det måske nødvendigt at fjerne en eventuel eksisterende konfiguration. Følg anvisningerne herunder.
Undersøg om der er en eksisterende konfiguration
Hvis routeren efter den har bootet viser System Configuration Dialog som vist i dialogbilledet nedenunder, har routeren ingen konfiguration liggende og du kan fortsætte til Konfiguration trin 1. Hvis routeren skriver en række fejlbeskeder på skærmen er det nødvendigt at Slette den eksisterende konfiguration
--- System Configuration Dialog ---
Would you like to enter the initial configuration dialog? [yes/no]: <yes>Slet eksisterende konfiguration
For at slette den eksiterende konfiguration skal man først logge ind på routeren. Vi bruger altid passwordet cisco, class eller Cisco her på skolen. Du bør således kunne logge ind som vist herunder. Hvis du mod forventning ikke kan logge ind er det nødvendigt at udføre proceduren password recovery procedure.
R5><enable>
Password:
R5#Efter du er logget ind på routeren kan du slette konfigurationen som ligger i en fil som hedder startup-config og genstarte routeren. erase startup-config slettet konfigurationen og reload genstarter routeren. Vist herunder.
R5#erase startup-config
Erasing the nvram filesystem will remove all configuration files! Continue?
[OK]
Erase of nvram: complete
R5#reloadAnd the Router reloads with a empty configuration
Konfiguration trin 1
Se eksemplet herunder
--- System Configuration Dialog ---
Would you like to enter the initial configuration dialog? [yes/no]: <yes>
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system
Would you like to enter basic management setup? [yes/no]: <yes>
Configuring global parameters:
Enter host name [Router]: <Viborg1>
The enable secret is a password used to protect access to
privileged EXEC and configuration modes. This password, after
entered, becomes encrypted in the configuration.
Enter enable secret: <cisco>
The enable password is used when you do not specify an
enable secret password, with some older software versions, and
some boot images.
Enter enable password: <class>
The virtual terminal password is used to protect
access to the router over a network interface.
Enter virtual terminal password: <cisco>
Configure SNMP Network Management? [yes]: <no>
Current interface summary
Any interface listed with OK? value "NO" does not have a valid configuration
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned NO unset up down
FastEthernet0/1 unassigned NO unset up down
Enter interface name used to connect to the
management network from the above interface summary: <FastEthernet0/0>
Configuring interface FastEthernet0/0:
Use the 100 Base-TX (RJ-45) connector? [yes]:<yes>
Operate in full-duplex mode? [no]: <yes>
Configure IP on this interface? [yes]:<yes>
IP address for this interface: <192.168.22.1>
Subnet mask for this interface [255.255.255.0] : <255.255.255.0>
Class C network is 192.168.22.0, 24 subnet bits; mask is /24
The following configuration command script was created:
hostname Viborg1
enable secret 5 $1$Q0eK$BS6PyvYOB0dfDILGrDYLc.
enable password class
line vty 0 4
password cisco
no snmp-server

end
[0] Go to the IOS command prompt without saving this config.
[1] Return back to the setup without saving this config.
[2] Save this configuration to nvram and exit.
Enter your selection [2]:<2>
