I. STATIC ROUTING SINGLE HOP AND MULTI HOP
I.1 - Static route single hop:
the objectif : R1 can ping IP Loopback R2 and vice versa.
First... we must configure the IP Address.
# Interface Configuration in R1
set interface lo0.0 family inet address 1.1.1.1/32
set interface em0.0 family inet address 12.12.12.1/24
# Interface Configuration in R2
set interface lo0.0 family inet address 2.2.2.2/32
set interface em0.0 family inet address 12.12.12.2/24
Second... we configure static route in R1 and R2, Because R2 is edge router, we configure R2 using default route.
# static route configuration in R1
set routing-options static route 2.2.2.2/32 next-hop 12.12.12.2
#static route configuration in R2
set routing-options static route 0.0.0.0/0 next-hop 12.12.12.1
Can use any linux distribution, I use Ubuntu Server 22.04 (Jammy Jellyfish)
okay let's go
1. File Hierarchy
Like the picture above, u can practice it. in the "/" contain some folders (blue color) and file(white color).
2. Navigating File
-Absolute Path : always starts with "/" (enter the root directory first)
example :
-Relative Path : not necessarily start with "/" (just customize with path location)
example :
*pwd : prints the full name (the full path) of current/working directory
ls: ls is a Linux shell command that lists directory contents of files and directories
example:
3. Creating File & Directory
touch : used to create a new empty file and to change the timestamps of existing file
example :
mkdir : used in Linux to create a new directory/folder
example:
4. File Manangement
cd: used to change the current directory of the terminal
example:
- VLAN 1 is the Default VLAN and can't be changed. yes is like factory default.
- NATIVE VLAN : by default NATIVE VLAN is VLAN 1 but can be changed to any VLAN, and used for switch, that do not supporting VLAN tagging ~ switch, that only supporting untagged vlan traffic.
- one of the many difference between Default VLAN and Native VLAN is , only one Default VLAN per switch, but per switch can handle multiple Native VLAN. ~ my favorite part for explanation.

What is Docker ?
- Docker is like vessel that carries container, yes container.
- Is many types of object on the vessel's containers, shoes, electronic, fruit, vegetable or many more.
it's very eficient because it carry a lot and departs once.
- on a computer, Docker can carry many services in one guest os without Virtual Machine.
- yes Docker and Virtual Machine is Different technologies but give almost the same solution.
