Cisco Router Basic configuration

-
The setup was configured in Packettracer, it is a network simulator by cisco.
The simple setup was implemented with three routers and three computers. The networks used with computers are 192.168.1.0, 192.168.1.64 and 192.168.1.128 with subnet mask 255.255.255.192 and the two networks which interconnects three routers are 2.1.1.0 and 3.1.1.0 with subnet mask 255.255.255.252.

Three console cables are connected to routers from computers to configure routers using terminal in computers.

Window when log in to Router - cli

The window for configurations without using cli









User mode, Enable mode and global configuration mode in a router
Connecting console cable
Connecting cables between routers using serial port
IP address configuration on a computer
Connecting to the router from terminal in computer using console cable
setting up the clock in the router in enable mode
show terminal command in enable mode
To stop DNS lookup in the router
To get the next line after pressing ctrl+z, otherwise we have to press enter to get next line on cli
Set a hostname for the router
Save the configurations

How to push a file into a docker container

-
Let's  see how to push a file into the container from the host.  We are assuming the test.html file is the file we are going to copy into the docker container.  web-application is container docker cp test.html web-application:/folderpath we can verify  after log in to the container. docker exec -it web-application bash And then check in the folder path and you will see the file there copied Sources : https://www.linkedin.com/events/kubernetes-freetechnicalworksho6807993779836985344/

Docker What, Docker? Opensource platform tool  Manages the containers Allow to build applications in a container with the libraries, binaried and dependencies run from anywhere Why Docker? portability light weight OS fast delivery(impact of light weight os) Multiple isolated OS Resource optimization Continous development and testing Architecture Docker Client Docker Host  Docker Hub(Registery) Also Docker images , Docker containers , Dcker Network and storages are contains in the architecture. Docker client is used to communicate with Docker hosts using Docker daemon is installed in Docker host. Clients are used to manage the Docker components and operations such as create, delete, pull, push, bulid, run etc. Docker client can connect to the Docker host remotly using REST API, UNIX sockets or using a network interface. Docker hub(Registery) is used to pull and push Docker images There are two types of docker hubs Docker Hub Online/Docker Hub

Project(on going) - IPv6 Fragmentation

-
An IP Datagram travels over different networks, each of which may have different MTU (Maximum Transmit Unit ) , which is the largest IP datagram that can be carried by a network. MTU - - maximum size of an unit which can be transmitted in a network and it depends on the network and media and how they be allowed to transmitted. also encapsulation....etc. It happens when the MTU values of hosts and routers are different from each other;         When we have two different type of network/media connected with router which have different MTU in such case router broke down packet to appropriate size regarding network/media type payload exceed the Maximum Transmission Unit in the interface. so the payload has to be chopped and put them into IP fragmented packets. they are:     -reassembled at destination     -each fragment is independent datagram        - could be routed in a different direction        - could be delivered out of order        - can be used to bypass IPS
