Ways to combine remote offices other than vpn?

Question

linux

Specifically, I would like to know how a provider can help in combining two or more remote offices? I heard, somehow through vlan forwarding, if there is something on the hub, please share or speak out based on your experience. Thank you.

Answer 1

VLANs are thrown by small providers, and even then mostly within the same city. Large ones are made using MPLS L3VPN/L2VPN/VPLS/EVPN technology. In detail, you can read the latest articles from the series "networks for the smallest" on Habré. As a rule, when purchasing a provider VPN, you are guaranteed some quality parameters and service availability, unlike regular Internet.

Answer 2

We in Engels, domru and rostelecom have a service for corporate clients called "private local area network". I have no idea how they implement it, but the speeds and pings are real as in LAN and work transparently, i.e. as if just stuck a string between 2 adjacent PCs. I must say right away that I saw this a little more than 2 years ago.
