The article is quite long, so if you read it patiently, you will definitely gain something.
Compared with other IT positions, the learning direction of network engineers is relatively bright. If you want to become a network engineer, Huawei certification is the best way to learn. The network engineer's learning from scratch is to start from the basic level of Huawei certification, which is HCIA, that is, start from the most basic what is an IP address and what is a switch.
Many old fans know that I like to share some learning routes for Huawei certification for network engineers, as well as some learning materials for network engineers. I will use some of my personal learning experiences to guide you through the Huawei certification learning route. Each technology will have relevant examples, and these will appear in the network engineer learning materials I share.
In addition, we will take you through the learning route of OSPF and BGP in medium and large networks. If you can understand the knowledge of HCIA and HCIP in Huawei certification, you will definitely have a place in the network engineer industry. Below I will share this network engineer learning route in detail:
