Our verdict on FRRouting
FRRouting (FRR) is an open-source software suite that provides IP routing services on modern Unix-like operating systems, including Linux and BSD. It is aimed at operators building software routers, route servers or routing hosts who need standards-based protocol support without a paid license. The suite includes routing daemons and Zebra, which interfaces with the operating-system kernel for routing operations. Its self-hosted model fits small, mid-market and enterprise teams that manage their own infrastructure.
FRR’s free GPLv2 model keeps the product focused on routing functionality rather than tiered subscriptions. Protocol coverage includes BGP and route-server behavior, RIP and RIPng, OSPFv2 and OSPFv3, IS-IS, Babel, EIGRP, LDP, PIM and OpenFabric. Virtual Routing and Forwarding, policy-based routing, Bidirectional Forwarding Detection and VRRP extend its use for segmented networks, failure detection and gateway redundancy. SNMP support provides a monitoring interface, while Zebra connects protocol decisions to kernel routing tables.
Deployment requires an operator-managed Unix-like host: installation documentation covers package-based installation and building from source. That approach gives teams control over the routing environment but places setup and ongoing administration with them. FRR is a strong choice for Linux operators who want broad protocol coverage, VRF and high-availability building blocks at no license cost. Teams that prefer vendor-managed routing, a turnkey appliance or a graphical onboarding experience should consider a different product category.
