SPOTO Club written 3 years ago

VPN is defined as a Virtual private network or a tunnel using an encrypted connection to secure the information communicated over the internet by any organization. There are several protocols for setting up the VPN, which is already being used in many enterprises. The VPN can be used on almost every platform, including Windows, Mac, Linux, etc. In simple words, a VPN provides a private network among public networks to hide the transmitted data, identity, etc.

The VPN is used to hide online identity, bypass the geo-blocks, secure online connections, prevent bandwidth throttling, etc. There are many countries where VPN is regulated, and using it for committing fraud is a punishable offense. However, the companies mostly use it to protect their secrecy of information, breach of which can lead to a significant loss. Therefore, the companies prefer using VPN to secure their online presence using VPN.

There are two VPN types, i.e., Layer 2 (l2) VPN and Layer 3 (l3) VPN. Layer 2 was used in the earlier days. It is now becoming replaced by the Layer 3 VPN technology; however, both have their pros and cons, which can be gone through to get the difference between layer two and layer 3 VPN technology.

The Layer 2 VPN is less scalable than the Layer 3 VPN, and the examples for Layer 2 VPN are LANE, IPLS, VPLS, EOMPLS, 802.1q, tunneling, etc., while the Layer 3 VPN examples could be MPLS VPN, IPSEC P2P, etc. The significant difference between Layer 2 and Layer 3 is the service provider’s involvement in the connectivity; layer two does not involve the service provider; however, layer 3 VPN connectivity consists of the service provider in communication.

Both the two aspects are covered in the IT certification courses offered by Cisco. IT professionals can define which type of VPN is required to secure internal office communications. These IT certs can vary starting from beginner entry-level up to expert level certification. Cisco is quite strict in taking these exams, and they are designed to check the required skills of IT professionals. Passing these certification courses means that the individual can handle the day-to-day task with all necessary skills as required by Cisco.

Therefore, if you are looking for learning resources, Cisco’s main course will be an excellent source to learn about configuring and troubleshooting Cisco devices. Besides those course books, the individual also has to spend time in the lab to grasp technical knowledge using the physical lab facility. Many other things can act as supplements to your studies. These can be joining boot camps offered by certified individuals cum trainers.
