Security is a primary concern for many organizations making the transition to cloud. In the blog, “Taking a Hybrid Cloud Approach to Security”, cloud provider Presidio shares how building a hybrid cloud enables you to maximize security while maximizing flexibility at the same time.
Security in this instance can be thought of in terms of risk. For example, sensitive data and mission-critical applications need a higher level of security than a devops test environment. The challenge for organizations is to accurately assess their risk and align their security strategy with their business objectives. Threats can come from outside – and inside – an organization. The best response to threats goes beyond just the technology underlying your data center and that of your cloud provider.
The truth is, your organization is unique. This means your security strategy is going to be unique as well. The foundation of a solid, comprehensive strategy is, of course, an enterprise-class architecture with end-to-end security. To be complete, however, security policies must be in place which meet the specific security needs of your organization and regulations of your industry.
The architecture must also be supported by procedures that enable the members of your organization to easily comply with these security policies. These procedures must be effective while at the same time not getting in way of the workflows or corporate culture already in place.
Developing – and successfully implementing – such a security strategy can be extremely complex. For organizations new to cloud, especially hybrid clouds, understanding the nuances of comprehensive security may be outside their expertise. This is why an experienced cloud provider is crucial to any secure hybrid cloud deployment. One size does not fit all, nor are all clouds created equal. The right cloud provider can be a powerful partner in maximizing your ability to benefit from a hybrid cloud.
How can you find the right partner? Ask how much they can do for you. Not just what they offer every customer. What can they bring to the table in terms of experience with your industry? Can they help assess your requirements and risks? Do they offer security beyond the commodity-based cloud offerings so common in the market?
A hybrid approach to cloud has much to offer organizations of all sizes. And when deployed with the right partners, you can have confidence in the security of your data and applications.

Given the tremendous interest in VXLAN with MP-BGP based EVPN Control-Plane (short EVPN) at Cisco Live in Milan, I decided to write a “short” technology brief blog post on this topic.
VXLAN (IETF RFC7348) has been designed to solve specific problems faced with Classical Ethernet for a few decades now. By introducing an abstraction through encapsulation, VXLAN has become the de-facto standard overlay of choice in the industry. Chief among the advantages provided by VXLAN; extension of the todays limited VLAN space and the increase in the scalability provided for Layer-2 Domains.
Extended Namespace – The available VLAN space from the IEEE 802.1Q encapsulation perspective is limited to a 12-bit field, which provides 4096 VLANs or segments. By encapsulating the original Ethernet frame with a VXLAN header, the newly introduced addressing field offers 24-bits, thereby providing a much larger namespace with up to 16 Million Virtual Network Identifiers (VNIs) or segments.
While the VXLAN VNI allows unique identification of a large number of tenant segments which is especially useful in high-scale multi-tenant deployments, the problems and requirements of large Layer-2 Domains are not sufficiently addressed. However, significant improvements in the following areas have been achieved:
- No dependency on Spanning-Tree protocol by leveraging Layer-3 routing protocols
- Layer-3 routing with Equal Cost Multi-Path (ECMP) allows all available links to be used
- Scalability, convergence, and resiliency of a Layer-3 network
- Isolation of Broadcast and Failure Domains
IETF RFC7348 – VXLAN: A Framework for Overlaying Virtualized Layer 2 Networks over Layer 3 Networks
Scalable Layer-2 Domains
The abstraction by using a VXLAN-like overlay does not inherently change the Flood & Learn behavior introduced by Ethernet. In typical deployments of VXLAN, BUM (Broadcast, Unicast, Multicast) traffic is forwarded via layer-3 multicast in the underlay that in turn aids in the learning process so that subsequent traffic need not be subjected to this “flood” semantic. A control-plane is required to minimize the flood behavior and proactively distribute End-Host information to participating entities (typically called Virtual Tunnel End Points aka VTEPs) in the same segment – learning.
Control-plane protocols are mostly employed in the layer-3 routing space where predominantly IP prefix information is exchanged. Over the past years, some of the well-known routing protocols have been extended to also learn and exchange Layer-2 MAC addresses. An early technology adoption with MAC addresses in a routing-protocol was Cisco’s OTV (Overlay Transport Virtualization), which employed IS-IS to significantly reduce flooding across Data Center Interconnects (DCI).
Multi-Protocol BGP (MP-BGP) introduced a new Network Layer Reachability Information (NLRI) to carry both, Layer-2 MAC and Layer-3 IP information at the same time. By having the combined set of MAC and IP information available for forwarding decisions, optimized routing and switching within a network becomes feasible and the need for flood to do learning get minimized or even eliminated. This extension that allows BGP to transport Layer-2 MAC and Layer-3 IP information is called EVPN – Ethernet Virtual Private Network.
EVPN is documented in the following IETF drafts
Integrated Route and Bridge (IRB) – VXLAN-EVPN offers significant advantages in Overlay networking by optimizing forwarding decision within the network based on Layer-2 MAC as well as Layer-3 IP information. The decision on forwarding via routing or switching can be done as close as possible to the End-Host, on any given Leaf/ToR (Top-of-Rack) Switch. The Leaf Switch provides the Distributed Anycast Gateway for routing, which acts completely stateless and does not require the exchange of protocol signalization for election or failover decision. All the reachability information available within the BGP control-plane is sufficient to provide the gateway service. The Distributed Anycast Gateway also provides integrated routing and bridging (IRB) decision at the Leaf Switch, which can be extended across a significant number of nodes. All the Leaf Switches host active default gateways for their respective configured subnets; the well known semantic of First Hop Routing Protocols (FHRP) with active/standby does not apply anymore.
Summary – The advantages provided by a VXLAN-EVPN solution are briefly summarized as follows:
- Standards based Overlay (VXLAN) with Standards based Control-Plane (BGP)
- Layer-2 MAC and Layer-3 IP information distribution by Control-Plane (BGP)
- Forwarding decision based on Control-Plane (minimizes flooding)
- Integrated Routing/Bridging (IRB) for Optimized Forwarding in the Overlay
- Leverages Layer-3 ECMP – all links forwarding – in the Underlay
- Significantly larger Name-Space in the Overlay (16M segments)
- Integration of Physical and Virtual Networks with Hybrid Overlays
- It facilitates Software-Defined-Networking (SDN)
Simply formulated, VXLAN-EVPN provides a standards-based Overlay that supports Segmentation, Host Mobility, and High Scale.
VXLAN-EVPN is available on Nexus 9300 (NX-OS 7.0) with Nexus 7000/7700 (F3 linecards) to follow in the upcoming major release. Additional Data Center Switching platforms, like the Nexus 5600, will follow shortly after.
A detailed whitepaper on this topic is available on Cisco.com. In addition, VXLAN-EVPN was featured during the following Cisco Live! Sessions.

If you are involved in designing, supporting or managing a data center, you will undoubtedly rely on technical support services from one or more vendors. Running your data center, there is always the risk of a hardware failure or being impacted by a software defect. While relatively rare, hardware does occasionally fail unfortunately. However you undoubtedly have technical support in place to deal with such problems. You may have invested in a few extra switches as backup, you may also have failover mechanisms in place. Almost certainly you will have a support contract in place with your Cisco partner or with Cisco, so you have break/fix expertise on tap for when something goes wrong. This is critical support for your business, no debate from me.
Engineer Under Stress!
Now, arguably the most important resource you have in your data center is not so much individual switches, routers or servers. It’s your engineers, those who design and support your data center. If they have a problem, where and how do they get help? Who helps them when they are stretched? When business pressures are telling? Of course, their colleagues and managers can and will help. Where, however, can they tap into additional sources of expertise so that they can become even more productive for you? This is where Cisco Optimization Services come in – including our award-winning Cisco Network Optimization Service (or “NOS” for short), Collaboration Optimization Service, and the one I’m involved with, Cisco Data Center Optimization Services.
