Summary of personal Cisco Study Notes

It has been a month since I learned how to configure Cisco routers. Although it is still superficial, it is also a little achievement.
The study notes are summarized as follows:
I. Theoretical knowledge:
Router principle and routing protocol Id = 350401994 & H = 1 & BPG = 2 & age = 0
A router is used to connect two as autonomous systems. The main router types include 12000, distributed layer router, and edge router.
1. Protocol and Encapsulation
(1) RIP routing protocol. A protocol used to calculate the number of Route hops. It cannot be used in a route network with more than 15 hops;
(2) ospe routing protocol. Link Status routing selection protocol;
(3) IGP routing protocol. It runs on an enterprise's internal network and is called the internal gateway protocol;
(4), EGP, and BGP routing protocol. External gateway protocol and Border Gateway Protocol;
Routing, IPX routing protocol.
Protocol, encapsulation of various protocols. HDLc, PPP, X.25, famerelay Frame Relay encapsulation, ISDN

Configure the following interfaces on the configuration interfaces of vswitches.
Fast Ethernet port fatethernet
Serial port serial
ISDN interface bir
Dialer interface dialer
Ii. basic configuration process and commands
1. Basic configuration command:
For more information about all commands, see [ccna 640-801 IOS command overview].
Http:// Id = 350402707 & H = 1 & BPG = 4 & age = 0
2. Basic configuration items
(1) host settings. Including host name and password.
(2) Remote Logon Settings. Including the logon method, quantity, and password. Here we mainly use virtual terminal vty
(3) Port definition. Define the IP addresses of different ports. Static Routing can be defined here.
(4) enable routing protocols and encapsulation. Configure dynamic routing and encapsulation. The following configuration process is not scrubbed or encapsulated.
3. simple configuration process
En enters privileged Mode
Config t enters global Mode
Hostname work1 password work set host name and password
Line vty 0 4 allow five virtual terminal connections
Username vty password vty name and SET Password
Config t
Int E0 defines a port
IP address defines the port IP Address
Config t
Router rip defines the rip route
Network Dynamic Routing
IP routing
IPX routing enable ip ipx Routing
Copy run start to save the current configuration. You can also use the write mem command to write the current configuration.

You can also set the route configuration by executing the dialog command after entering the privileged mode.
Dialog command settings:
Wocould goulike to enter the in‑configuration dialog? [Yes]
Press Y or enter to enter the dialog setting process.
First wowould you like to see the current interface summary? [Yes]
Then, the route entry is set to global parameters.
Using ING Global parameters;
Enter host name [router]: Set the vro name
The enable secret is a one-way cryptographic secret used instead of the erable password when it exists.
Enter enable secret: Set the ciphertext to enter the privileged Mode
Enter virtual terminal password: Set the password used to access the virtual terminal.
Check whether the supported network meanings are set.
Configure SNMP Network Management? [Yes]:
Configure decnet? [No]:
Configure appletalk: [No]:
Configure IPX? [No]:
Configure Ip? [Yes]:
Configure IGRP ruuting: [Yes]:
........................................ ..
If the port number is configured to access the server, the system also sets the asynchronous port parameter.
Configure async lines? [Yes]:
Asyncline speed [9600]: sets the maximum line speed
Corfigure for hwflow control: [Yes]: whether to use hardware Flow Control
Configure for modems: [Yes/No]: Yes whether to set the modem
Configure fot default chat serept: [Yes]; whether to use the default Modem
Configure for did-in IP sll/PPPP access: [No]: Yes whether to set asynchronous PPP Parameters
Configure for Dynamic IP address? [Yes]: whether to use a dynamic IP Address
Configure Default IP addresses: [Yes]: whether to use the default IP Address
Configure for TCP Header Compression? [Yes] whether to use TCP Header Compression
Configure for routing updates on async links? [No]: whether y uses route table update on the asynchronous Port
Interface parameter configuration
Logging interface ethernet0: Ethernet port configuration
Is this interface in use? [Yes]: whether to use this interface
Configure IP on this interface? [Yes 'Whether to set the IP Parameters of this interface
IP address for this interface: XXXX. xxxx. XXX. XXX set the IP address of this interface
Number of hES in subnet field [0]: sets the interface IP mask.
Class cnetwork is XXXX. XXX. xx. xx subnet bits: mask is/24
