Lesson 1 SDWAN network model, laboratory configuration and image download

Table of Contents

When a company has many branches, the branches are connected through MPLS lines, the Internet, etc. If traditional configurations such as dmvpn are used, it is difficult to manage, and it is also difficult to transmit traffic between routes. If you have to do this manually, it’s easy to make mistakes, or you can’t see which application the traffic goes to, or when the branch office gets a new router, the administrator has to go to the site to configure it.

=> Cisco sdwan solution can do the following:

Autocomplete routing part Between branches, just add the wan router (vEDGE) at the branch to the NMS (vmanage, vsmart, vbond) and it will automatically connect to the other branch. What does the administrator need to block later? This is done by VSMART, which automatically redistributes routes between vEDGEs to communicate with each other (OMP protocol).

When a new branch router is added Then you just need to set an IP for it to connect to NMS (vmanage, vsmart, vond). Then push the remaining configuration up and down the network management system. The administrator only needs to operate through the webgui, which is more convenient than typing commands. This can be done once for many routers. (mechanism using templates). Unfortunately, pressing configure will cause the connection to be lost; vEDGE will automatically roll back to the old configuration.

light the way Include running applications

Traffic is transmitted over a secure WAN Because it’s encrypted with ipsec (which itself is true; I just enabled IPsec)

-….There are a lot more

The basic diagram includes 2 sites:

Set up a laboratory on EVE-NG:

The CPU I am currently using: e2650v2 8 cores, 16 threads runs smoothly.

RAM: The above models use about 25-30GB RAM (should come with about 40GB+ RAM)

Image eve-ng: can be downloaded at:

How to add to eve-ng: see homepage

I am using version 19.2.31

After the addition is completed, the management interface will be displayed as:
