As AI workloads, cloud-native functions, and massive-scale infrastructure push networks to their limits, the stress to show interoperability in multivendor environments has by no means been better. Cisco addressed that requirement head-on with the Cisco N9000 Sequence on the European Superior Networking Check Heart (EANTC), demonstrating industry-leading efficiency throughout VXLAN EVPN and Time Synchronization check streams.
Cisco at EANTC Transport and Cloud Networks Interop Check 2026
Because the {industry}’s most rigorous proving floor, the annual Transport & Cloud Networks Interop Check at EANTC in Berlin serves as an impartial, impartial platform for validating the effectiveness of open, standards-based networking. By convening main {hardware} and software program distributors to stress-test interoperability, efficiency, and safety, EANTC helps be sure that numerous applied sciences combine seamlessly. This rigorous analysis confirms that new options are prepared for instant, dependable deployment in essentially the most demanding service supplier and enterprise networks.
In 2026, Cisco participated in each EANTC Transport & Cloud Networks Interop Check group demonstration—together with VXLAN EVPN, MPLS EVPN, SR-MPLS, SRv6, Orchestration and Automation, and Time Synchronization—using each the Cisco N9300 and Cisco 8000 Sequence platforms (Determine 1). This weblog focuses on the VXLAN EVPN and Time Synchronization check group outcomes.
Confirmed, open and safe: Cisco N9300 at EANTC 2026
Along with Cisco N9000 Sequence Switches, for the primary time Cisco N9300 Sensible Switches have been used within the VXLAN EVPN and Time Synchronization check group demonstrations. Whereas the occasion lined a variety of know-how and Cisco options, this weblog put up focuses completely on the participation with Cisco N9300 Sequence Switches.
In line with earlier years, many of the taking part distributors agreed on the next set of VXLAN EVPN check eventualities:
- Symmetric IRB with VLAN-based​
- BGP unnumbered underlay
- VXLAN EVPN with IPv6 VTEPs
- EVPN and IPVPNv4 interworking
Highlights from the EANTC Interoperability Check 2026
VXLAN EVPN Group Coverage
The VXLAN Group Coverage allows the classification of related endpoints (EPs) and exterior assets into distinct Safety Teams (SGs). By defining and making use of Safety Group ACLs (SGACLs) between these teams, directors can successfully govern communication throughout the material. Determine 2 exhibits {that a} machine from Vendor A can ship site visitors to a Cisco N9000 change throughout a VXLAN EVPN material, and the safety guidelines (primarily based on the Safety Group Tags) will nonetheless be enforced accurately to allow or deny communication between the EPs.
These constructs present a strong resolution for Cisco NX-OS-based standalone N9000 switches to make sure constant safety posture. As an early adopter of VXLAN Group Coverage Possibility (GPO), Cisco efficiently demonstrated interoperability with different distributors that are actually creating comparable function units.
Interoperability between symmetric and uneven IRB
Built-in Routing and Bridging (IRB) operates in two major modes: symmetric and uneven. In real-world deployments, it is not uncommon to come across environments the place gadgets throughout the identical EVPN area are configured with completely different IRB modes. To make sure seamless communication, these modes should interoperate in accordance with the requirements outlined in draft-ietf-bess-evpn-modes-interop. In the course of the testing, Cisco showcased profitable end-to-end interoperability in a hybrid state of affairs, the place a Cisco machine functioned seamlessly alongside a associate vendor configured for uneven IRB (Determine 3).
N9300 Sequence Sensible Switches and VXLAN EVPN check
In the present day’s information middle operators want less complicated, safer methods to scale their environments with out the complexity of managing a number of, disparate safety options. Cisco redefined information middle networking with the N9300 Sequence Sensible Switches, a single platform that unifies networking and safety right into a unified, future-proof structure.
The N9300 Sequence gives strong Layer 4 segmentation throughout each single- and multi-fabric deployments. By embedding superior safety immediately into the material, this platform enhances visibility and reduces complete price of possession (TCO).
This dedication to built-in safety was additional validated throughout the latest EVPN interoperability assessments, the place Cisco efficiently participated within the Symmetric IRB check with the Cisco Silicon One–primarily based N9348Y2C6D-SE1U good change (Determine 4).
PTP over MACsec
MACsec (IEEE 802.1AE) secures Precision Time Protocol (PTP) site visitors by offering Layer 2 encryption, making certain confidentiality and integrity whereas defending in opposition to eavesdropping and tampering. Cisco efficiently exhibited PTP operation over MACsec at 100GE utilizing the N9K-C93400LD-H1 and N9K-C93180YC-FX3 switches (Determine 5).
Whereas enabling MACsec launched inherent path asymmetry and time error, Cisco exactly characterised these results and utilized the mandatory delay and asymmetry compensation to fulfill the check’s rigorous timing efficiency necessities. These outcomes mark a big development in PTP safety, confirming that useful interoperability could be achieved over MACsec with out compromising the strict time-error limits required for demanding synchronization functions.
The ability of multivendor alternative
Interoperability empowers organizations to combine and match applied sciences to align with particular enterprise necessities, whether or not they’re adopting new improvements or refreshing current infrastructure. That is the place VXLAN BGP EVPN multivendor interoperability testing is crucial, because it validates how options from completely different producers perform collectively in real-world eventualities. This 12 months, 12 distributors, together with Cisco, participated in these rigorous assessments. As an {industry} chief, Cisco stays a devoted participant in these interoperability occasions and continues to contribute actively to world standardization our bodies (Determine 6).
From EANTC to the Upperside World Congress
After efficiently scorching staging the Cisco N9300 Sequence Switches at EANTC in Germany (Determine 7), Cisco additionally showcased a stay demo on the VXLAN GPO interoperability on the Upperside World Congress (previously the MPLS World Congress) in Paris, March 24–26. The demo video highlights this interop check case.
EVPN continues to evolve, proving its versatility and widespread adoption by means of profitable multivendor interoperability occasions like these hosted by EANTC. Whereas the usual continues to be refined by its authentic authors, the participation of a dozen distributors proves that it has broad {industry} acceptance. Trying forward, every new 12 months and set of check eventualities will undoubtedly drive additional innovation, uncovering new use instances and options which are important for buyer success.
