Router and Switch Technology learning Guide

routers and switches are the basis of the entire network learning, whether you are the enterprise management of party A, or party B's network engineer, or is preparing to test Cisco, or Huawei such It certification of friends, all need to learn. So in the end should be how to better study, or master these knowledge, today I will come to you.

This is the sum of their own, the network part of the "routing" this piece of technology Division . You can also think of this as your own in the network technology learning in the mind map, or study outline.

So how does this figure work? Specifically, the

The routing part in the network. I split this up into 3 chunks of technology.

first chunk: static route: This includes the configuration of the static route and the default route, as well as the configuration of the static floating route .

first chunk: Dynamic routing: This is the "4 Big" routing protocolthat is often said, (RIP OSPF EIGRP and BGP)

The third chunk: In this picture I myself put this part of the content referred to as "other "means routing knowledge points in addition to static routes and dynamic routes. which contains (NAT DHCP ACL and Policy route)

Let's take a look at the knowledge points in this section.

This is what I have summed up: "Exchange" this part of the specific knowledge points , the exchange actually refers to the study is the network switch configuration and debugging.

here I put in exchange. Divided into 2 parts by type .

The first part is "Two-layer Exchange". In this part does not need to introduce too much, because in the actual enterprise application aspect, the second layer switch also is called "The Fool Switch" is the direct plug in the network cable to be possible to use. Do not need to be configured. This part is mainly to understand the principle of the switch MAC Address table.

The second part is: three-layer exchange. This is the focus of the entire switch technology learning, but also in the work behind the most commonly used technology, in this contains 3 large chunks

The first piece is ; VLAN Partitioning and routing between VLANs.

The second piece is STP: Primarily to prevent switch loops.

The third piece is redundancy: The main thing is to learn The EC link bundles and HSRPVRRP such technologies.

I have summed up this learning guide for routing and switching, or learning an outline. Just for the learning of routers and switches. such as the current more popular MPLS VPN or ASA firewall, this I put them in the firewall this part.
