VyOS provides a freerouting platform that competes directly with other commercially available solutions from well-known network providers. Because VyOS is run on standard amd64 systems, it can be used as a router and firewall platform for cloud deployments.[3][4] VyOS can also be optimized to achieve routing at 100Gbps.[5]
Besides being open-source, VyOS also offers subscription-based support, which includes pre-built images for cloud and virtual environments and LTS images for the 1.3 and 1.4 series.
History
After Brocade Communications stopped development of Vyatta in 2013, a group of enthusiasts created an open-source fork[6][7] called VyOS, based on the last community edition, Vyatta Core 6.6R1.[8]
They founded Sentrium S.L,[9] a Spanish company dedicated to providing support and development for the VyOS project. On October 9, 2024, Sentrium S.L. was renamed VyOS Networks Iberia and was acquired by VyOS Networks Corporation, becoming its subsidiary.[10]
Routing and Protocols: BGP (IPv4 and IPv6), OSPF (v2 and v3), RIP and RIPng, policy-based routing, BGP-LU and enhanced route filtering. IPv4, IPv6, QoS.
Firewall and NAT:Stateful firewall based on nftables, zone-based firewall, all types of source and destination NAT (one to one, one to many, many to many), NAT64/DNS64.
High Availability and Load Balancing: VRRP for IPv4 and IPv6, ability to execute custom health checks and transition scripts; ECMP, stateful load balancing, failover routes.
Management and Configuration: Junos-style CLI[12] with commands like run, set, delete, show, commit, commit-confirm, compare and versioning.[13] Rollback without reboot,[14] PKI repository
Platform and Image Support: VyOS images can be created using vyos-build for the following platforms: amd64, ISO, and cloud images for AWS, Azure, Edgecore, XCP-NG, Qemu/Proxmox, VMware.
