RtBrick RBFS review
A multiservice edge network OS for operators combining routing, subscriber services and CGNAT.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
RtBrick RBFS is a network operating system for telecom operators that separates routing software from supported bare-metal switch hardware. It targets providers building broadband access, edge, metro, CGNAT or peering services, from smaller local carriers to large network operators. Depending on the role, it can operate as a Broadband Network Gateway or a peering router, making it relevant where a provider wants several network functions on a multiservice edge platform rather than a general-purpose virtual router.
Its feature breadth is oriented to service-provider networks: IP and MPLS routing includes BGP, IS-IS, OSPFv2/v3 and static routing, alongside LDP and segment routing. Layer 2 options include L2X, EVPN-VPWS and BGP-signaled L2VPN. Broadband subscriber management supports PPPoE, IPoE and L2TPv2, while CGNAT and BNG functionality address access-edge requirements. For operations and automation, RBFS provides CLI, NETCONF, RESTCONF/YANG, REST APIs and telemetry streaming, plus zero-touch provisioning for supported switches. High availability includes active/active and active/standby redundancy modes. This breadth suits operators consolidating routing and subscriber-facing services; teams seeking a lightweight router for ordinary office networks are unlikely to need this scope.
Deployment and purchasing call for planning. RBFS runs on supported bare-metal switches, with deployment options also described as virtual machine, container or hardware appliance. The documented limited-functionality VM image is for testing; production deployments use supported hardware platforms. A 30-day trial is available, but there is no free plan. According to RtBrick's pricing information, license costs vary by scenario and volume, with buyers directed to a pricing calculator rather than a fixed published price. Providers should evaluate hardware fit and license costs against their intended use cases before choosing it; organizations without telecom-scale edge or subscriber-management needs should consider a narrower routing product.
RtBrick RBFS pros and cons
- Where it wins
- Supports IP/MPLS routing, L2 services and broadband subscriber management
- Combines BNG functionality and CGNAT on a multiservice edge platform
- Offers CLI, NETCONF, RESTCONF/YANG, REST APIs and telemetry streaming
- Where it doesn't
- Production deployment requires supported hardware platforms
- License pricing varies by scenario and volume and requires sales contact
- Its focus on telecom network operators limits fit for general-purpose routing
