Juniper Certification | JNCIA Enterprise Routing & Switching | Day-3 Ethernet LAN overview

Building Ethernet LAN

On this module you are going to a networking term in PC and printers are just know as end-user devices, hosts, or it's just devices. As i already mentioned that a geographically limited network is called a Local Area Network or LAN.
The Pros and Cons of Local Area Network (LAN) - Cascade Business News

In Ethernet, we can see that it defines rules such as frame format as well as how computers communicate with each other over a single wire shared by all devices on network. When it comes to Ethernet standards that there is the protocol that controls access to the network and finally there is frame format.

Ethernet was originally deployed with multiple computers connected to the same physical wire or cable. This physical network topology or layout is is called shared bus or network segment receive it. But if there is break in cable, devices can no longer communicate. By the way the network segment refers to the group of network devices that compete with each other for access to the wire.

When, we need to connect to the network segment a device uses a network interfcae controller or NIC and Ethernet cabling or a wireless NIC. That Ethernet operates at layer 1 and 2 which you might alreay remember that the physical layer and the data link layer defines such things as the connection speed and type of cabling.

Stay tuned for more information on getting started with networking and preparation for juniper enterprise routing and switching.

Block websites or applications using SRx Firewall

By Published on
Hi, everyone on today we are going discuss on how to block websites or applications now this is trending news that many officials social  media accounts are hacked. We will see in juniper SRx Firewall. Some of the websites are not easy to block using web filter because they used signature and dynamic IPs, but we can block through Application Firewall. This example uses following zones and interfaces configuration. The client system is connected to the ge-0/0/0.0 interface with IP address 4.0.0.254/24. It is part of the trust zone. The server system is connected to the ge-0/0/1.0 interface with IP address 5.0.0.254/24. It is part of the untrust zone. • Configuration 》CLI Quick Configuration To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, copy and paste the commands into the CLI at the [edit] hierarchy level, and then enter commit from configuration mode.

Juniper Certification | JNCIA-JUNOS | Day-7 What is SDN and Products in Juniper

By Published on
On this particular day we are going to see on topic called SDN in Juniper. What is SDN ? SDN is a network software defined in networking term as Software Defined Networking. That this software do not run some Junos OS because there are group of designs made for juniper networking into cloud based solutions are made.  These are some products you need to know in juniper; NFX series are network services platform used in junos as customer premises equipment (CPE), that they are designed with these features : to provide very fast custom services  with delivery on demand they are secure on-premises can run and chains with multiple virtualisation network it functions simultaneously in an open environment   it also supports embedded vSRX security functionality Contrail Cloud it is just suite of products that enabling SDN does : network function virtualisation (NFV) and services done in cloud environment   it utilizes open technologies such as Op

Juniper Certification | JNCIA-JUNOS | Day-4 Transit Traffic Processing

By Published on

On this session we will proceed to Transit Traffic Processing consists of all the traffic that enters an ingress (i.e., an action of going in or entering) a network port, it is compared against the forwarding table entries and it is finally forwarded out an egress (i.e., action of going out or leaving) the network port toward its destination.  A forwarding table entry for a destination must exist for the device running the Junos OS to successfully forward transit traffic to that destination. A Transit Traffic passes through the fo rwarding plane only and is never sent to or processed by the control plane only and it is never sent to or processed by the control plane. By processing transit traffic through the forwarding plane only, platforms running the Junos OS can achieve predictably high in performance rates. From the above image we can see that Transit Traffic can be both ; Unicast Multicast I n Unicast transit traffic which enters one ingress port and it is transmi
