History¶
VyOS is a Linux-based network operating system that provides software-based network routing, firewall, and VPN functionality.
The VyOS project was started in late 2013 as a community fork of the GPL portions of Vyatta Core 6.6R1 with the goal of maintaining a free and open source network operating system in response to the decision to discontinue the community edition of Vyatta. Here everyone loves learning, older managers and new users.
VyOS is primarily based on Debian GNU/Linux and the Quagga routing engine. Its configuration syntax and 命令行接口 are loosely derived from Juniper JUNOS as modelled by the XORP project, which was the original routing engine for Vyatta.
In the 4.0 release of Vyatta, the routing engine was changed to Quagga. As of VyOS version 1.2, VyOS now uses FRRouting as the routing engine.
How is VyOS different from any other router distributions and platform?
It’s more than just a firewall and VPN, VyOS includes extended routing capabilities like OSPFv2, OSPFv3, BGP, VRRP, and extensive route policy mapping and filtering
Unified command line interface in the style of hardware routers.
Scriptable CLI
Stateful configuration system: prepare changes and commit at once or discard, view previous revisions or rollback to them, archive revisions to remote server and execute hooks at commit time
Image-based upgrade: keep multiple versions on the same system and revert to previous image if a problem arises
Multiple VPN capabilities: OpenVPN, IPSec, Wireguard, DPMVPN, IKEv2 and more
DHCP, TFTP, mDNS repeater, broadcast relay and DNS forwarding support
Both IPv4 and IPv6 support
Runs on physical and virtual platforms alike: small x86 boards, big servers, KVM, Xen, VMware, Hyper-V, and more
Completely free and open source, with documented internal APIs and build procedures
Community driven. Patches are welcome and all code, bugs, and nightly builds are publicly accessible
