CCNA English - Lecture 8: Basic Routing
What are community routers and routes?
A router is a machine that works in layer three and sends records packets from one community to another. And community route is the way to ship statistics packets from one community to every other network.
Basic router block diagram:
Flash memory:
Flash reminiscence is used to save the working system.
Radam:
RAM is used to keep routing desk statistics and going for walks configuration files.
Environ:
Environ is used to save startup files.
There are typically three kinds of routes:
- Static route
- Dynamic route
- Default route
StaticRout:
Static routes are used for smaller networks. If the route modifications at some stage in this routing, it has to be up to date manually.
Static Route's Command Scene Tax is:
Ip route dest-ip subnet {next-hop-ip / interface
Dynamic route
Dynamic routes are routes that exchange spontaneously over time. As a result, there is no want to do something manually. Any route adjustments are mechanically delivered to the routing table.
Default route
If no route is exact for a destination, the default route is the route that the router chooses as its default.
Router Basic Security Setup
Cisco mode configuration method
Cisco routers typically have four modes.
- EXE mode
- Vi Privilege mode
- Global configuration mode
- Interface mode
EXE mode
The person EXE mode of Cisco routers is the regular operation mode. After loading the Cisco device, iOS masses and comes in EXE mode. The image for EXE mode is ">". The process for giving passwords in this EXE mode is described below: -
Exe mode command
Router>; enRouter # configure terminal
Enter configuration commands, one per line. End with CNTL / Z.
Router (config) #line console 0
Router (config-line) #password cisco123
Router (config-line) #login
Router (config-line) #exit
Router (config) #exit
% SYS-5-CONFIG_I: Configured from console with the aid of console
Router # wr
Privilege mode:
Advanced operation mode is the privileged mode of Cisco routers. The image of Privileged Mode is “#” The password configuration guidelines in Privileged Mode are described below:
Router> encounter # configure terminal
Configuring from terminal, memory, or community [terminal]?
Enter configuration commands, one per line. End with CNTL / Z.
Router (config) #enable password
Router (config) #enable password titas123
Router (config) #exit
% SYS-5-CONFIG_I: Configured from console by way of console
Router # wr
Global Configuration mode:
Global configuration mode is the operation of the place a configuration command is given and it works on the entire device. But if you prefer to go to world configuration mode, you have to go to privileged mode first.
Router> enRouter # configure terminal
Configuring from terminal, memory, or community [terminal]?
Enter configuration commands, one per line. End with CNTL / Z.
Router (config) #
Interface mode:
You have to go into the mode to configure the precise co-interface of the Cisco device. Here's how to configure a port:
Router> enRouter # configure terminal
Enter configuration commands, one per line. End with CNTL / Z.
Router (config) #interface fastEthernet 0/0
Router (config-if) #ip tackle 192.168.60.1 255.255.255.0
Router (config-if) #no shutdown
I am ending the fundamental routing right here like today. Our subsequent tutorial is Static Routing.
