Ruijie RG-NBS Enterprise Switch: Campus Network Guide (2026)
The Ruijie RG-NBS Enterprise Switch series comprises L2 and L3 switch models designed for the access and distribution layers at campus scale. With enterprise protocols such as stacking, MLAG, OSPF, and BGP, it provides high availability and scalable routing. Beyond the Reyee NBS series, it forms the layers near the backbone of large-scale enterprise networks and can be managed centrally with Ruijie Cloud.
What is the Ruijie RG-NBS enterprise switch?
The Ruijie RG-NBS series is a family of managed switches designed for the access and distribution layers of the enterprise LAN. It connects a large number of endpoints at campus scale, manages inter-VLAN routing, and supports high-availability technologies such as stacking and MLAG.
An enterprise network generally consists of three layers: access (where endpoints connect), distribution (which aggregates and routes the access switches), and core (the high-speed backbone). The RG-NBS series targets the access and distribution layers of this architecture. Its difference from the Reyee NBS series lies in its larger scale, higher availability, and deeper routing capabilities.
This series is designed to build a stable and scalable wired infrastructure in campuses with hundreds or even thousands of users. Sora Yazılım plans RG-NBS switches as an end-to-end architecture together with enterprise RG-AP access points and the core layer.
For details on the product family, you can review our Ruijie RG-NBS enterprise switch product page. Sora Yazılım carries out the VLAN, routing, and redundancy design from start to finish.
An enterprise switch does much more than simply provide ports: it prioritizes traffic, enforces security policies, offers redundancy against faults, and ensures the observability of the network. The RG-NBS series delivers these capabilities at enterprise scale while retaining Ruijie's price advantage; this makes it possible for large campuses to build a solid infrastructure even under budget pressure.
Layered network architecture
Enterprise networks are designed with a three-layer architecture comprising access, distribution, and core. The RG-NBS series handles the access and distribution layers, while the core layer is generally built with high-capacity switches such as the RG-N18000.
| Layer | Role | Typical switch |
|---|---|---|
| Access | Connects endpoints, powers PoE | RG-NBS (L2/L2+) |
| Distribution | Aggregates access, routes VLANs | RG-NBS (L3) |
| Core | High-speed backbone | RG-N18000 series |
This layered approach makes the network both scalable and manageable. Each layer has a clear role; a change in one layer affects the others to a minimal degree. As the access layer grows, new switches are added, the distribution layer aggregates them, and the core layer carries all traffic at high speed.
In small and mid-sized campuses, the access and distribution layers can be combined (collapsed core); in very large networks, the three layers are clearly separated. The right architecture is designed according to the organization's current scale and future growth.
Redundancy is essential in the connections between layers. The paths from access to distribution and from distribution to core are designed with dual links; this way, a single cable or port failure does not halt service. Loop prevention protocols (RSTP/MSTP) block network loops in redundant topologies, while link aggregation both increases bandwidth and provides path redundancy.
The scale of segmentation also affects the architecture. In large campuses, there can be dozens or even hundreds of VLANs; each department, security zone, or device class is kept in a separate segment. The RG-NBS's L3 routing capability manages traffic between these segments efficiently while allowing security policies to be applied layer by layer.
L2/L3 and dynamic routing
In addition to L2 switching, the RG-NBS series supports inter-VLAN routing and dynamic routing protocols such as OSPF and BGP on its L3 models. This ensures that traffic is routed efficiently and scalably in large, segmented networks.
Static routing is sufficient in small networks; however, dynamic routing protocols are required in enterprise environments with a large number of VLANs and subnets. OSPF is the most widely used protocol for intra-campus routing; it automatically adapts to changes in the network topology and calculates the shortest path.
BGP, meanwhile, is used for routing between different autonomous systems, especially in data center and multi-site networks. The fact that RG-NBS L3 models support these protocols means that the series can take on a strong role not only at the access layer but also at the distribution layer. This flexibility makes it easier to add new layers as the network grows.
For load sharing, techniques such as ECMP (equal-cost multi-path) balance traffic across multiple paths, both increasing performance and providing redundancy. For gateway redundancy, VRRP-like protocols provide seamless failover in the event that the default gateway fails. Together, these mechanisms form the resilience of the enterprise network.
High availability: stacking and MLAG
The RG-NBS series provides high availability with stacking and MLAG (multi-chassis link aggregation). Stacking makes it possible to manage multiple switches as a single logical device, while MLAG guarantees uninterrupted operation even if one switch fails.
Stacking has two major benefits: management simplicity and redundancy. Stacked switches are managed from a single IP address; configuration is done once and applied to the entire stack. At the same time, when one member of the stack fails, the others take over to keep the service running.
MLAG enables servers or access switches to connect to two different distribution switches simultaneously. This way, the connection is not dropped even if a distribution switch or a cable fails. This redundancy is the cornerstone of network design in enterprise environments that cannot tolerate downtime; it eliminates the single point of failure.
Maintenance and update processes also affect availability. In a stacked or redundant architecture, while one switch is being updated, another member carries the traffic; this way, firmware updates can be performed without service interruption, without having to wait for after hours. This is an important operational advantage for enterprise environments that operate 24/7.
PoE and campus design
With its PoE+ and PoE++ (802.3bt) models, the RG-NBS series powers a large number of access points, IP cameras, and IP phones from the access layer. A high PoE budget provides the power that dense wireless deployments require.
In enterprise campuses, hundreds of access points and cameras are powered via PoE; this makes the total power budget per switch a critical design criterion. Because Wi-Fi 6E and Wi-Fi 7 access points draw more power, PoE++ support is important for a future-ready infrastructure.
Campus design addresses the PoE budget, uplink capacity, redundancy, and VLAN structure together. Sora Yazılım calculates from the outset the devices each access-layer switch will power and the power required; it plans the wireless-side requirements in harmony with the enterprise RG-AP design. In addition, PoE ports can be managed remotely; when an access point does not respond, the relevant port is restarted remotely (PoE power cycle), resolving the issue without a site visit.
Observability is an integral part of the enterprise switch. Metrics such as port utilization, error counters, PoE consumption, and temperature are continuously monitored; anomalies generate alerts. This proactive monitoring makes it possible to catch a problem before it affects users and to base capacity planning on data.
Connectivity to the core layer
RG-NBS distribution switches connect to the core layer with high-speed uplinks. In large campus and data center environments, the core is built with modular, high-capacity switches such as the RG-N18000 series.
The distribution layer aggregates the traffic of the access switches and forwards it to the core. The sufficiency of this connection's capacity determines the overall performance of the network; if a bottleneck occurs, all users are affected. For this reason, the uplinks between distribution and core are generally designed to be redundant and high-speed (10G/25G/40G).
For details on the scale and capabilities of the core layer, you can review our Ruijie RG-N18000 core switch guide. The holistic design of the access, distribution, and core layers determines the long-term success of the enterprise network.
Fiber optic is generally used in the connections to the core; the distance and speed limits of copper cabling make fiber essential at campus scale. SFP+ and QSFP module slots make it possible for the switch to accommodate different fiber types and speeds. This flexibility helps optimize cost by making use of the existing cabling infrastructure.
The difference between NBS and RG-NBS
While the Reyee NBS series offers streamlined management at SMB scale, the enterprise RG-NBS series provides higher availability and scale at campus scale with stacking, MLAG, and advanced routing (OSPF/BGP).
The boundary between the two series is the size of the network and the availability requirement. In a single-location, mid-sized network, Reyee NBS is sufficient. In enterprise campuses that require high availability, multi-layer routing, and high port density, RG-NBS comes into play. For the SMB side, you can review our Reyee NBS series guide. The fact that both series can be managed on the same Ruijie Cloud platform allows a growing business to build its access layer with Reyee and strengthen the distribution and core with the enterprise series as the scale grows; this gradual transition protects the investment.
