Cisco internet edge design

The Secure Edge is a place in the network PIN where a company connects to the public Internet, service providers, partners, and customers. As internal company users reach out to websites, use email and other collaboration tools, and as remote workers and customers reach in, the services of the network must remain both accessible and secure. SAFE simplifies security by starting with business flows, then cisco internet edge design their respective threats with corresponding security capabilities, architectures, cisco internet edge design, and designs. SAFE provides guidance that is holistic and understandable.

By Internet Edge, I specifically mean connecting your data center s to the Internet. For those who liked the SD-Access blog series: I have a few more SD-Access blogs fermenting in my brain and hope to be posting them after this series. Teaser: SD-Access Transit with two data centers and two pairs of fusion firewalls. There are some things to be aware of and design for. Ahem, so Internet Edge. More specifically, how you design the Internet connectivity in a data center or two.

Updated: Nov 2, Ready to live on the edge? In the last design post we talked about remote access VPN, but in this 4th installment of the network design scenario series we will take a detailed look at designs for the network edge. What is the network edge? The network edge is where your network and outside networks connect. In the enterprise world this is your path out to the internet, in the provider world this is generally where you connect to upstream providers or peers. We will cover high and low level designs, different types of topologies such as SMB, enterprise and service provider SP , look at the building blocks, redundancy options and other considerations. How do I fail over? I feel this is probably one of the less understood areas of networks for a lot of folks, perhaps because Border Gateway Protocol BGP is very integral to it. Some might struggle with how to perform fail over properly or there are just critical details that are often overlooked. I intend this post to be a detailed guide as much as possible to try and provide everything you need to understand and help design your network edge.

The behavior should be deterministic and predictable which can be achieved with proper BGP configuration and manners.

For cloud-enabled enterprises, the availability of their Internet facing-infrastructure is of critical importance. Cisco found that an average enterprise uses cloud services. Even relatively short Internet outages will adversely impact mission-critical cloud workloads. This results in significant costs and damage to reputations. Many enterprises may be unaware of just how significant their internet services have become to their overall business viability. The aim of this post is to outline four 4 alternate internet designs that address the shortcomings of a single unreliable internet link. Only internet-facing routers are in scope for this discussion. They are the routers shaded in red shown in Figure 1. Option 1 is known as a single-homed design. It is the simplest, cheapest, and least reliable since it has multiple single points of failure.

If you are taking the BGP route but aren't familiar with prefix lists and route-maps you should definitely do some reading. Ahem, so Internet Edge. Security Capability Threat Firewall: Stateful filtering and protocol inspection between segments in the data center. Continuing, looking at the above diagram we see Azure and Lumen connections shown on each side of the diagram which could be completely different geographic regions. See a cisco syntax below for example, but the same concepts applies to most vendors. This firewall can control ports and, ideally, help stop crypto locker and other malware from spreading from users to servers. Accelerated encryption of data services. Intrusion Prevention: Blocking of attacks by signatures and anomaly analysis. Threat Intelligence: Contextual knowledge of existing and emerging hazards. Each of these layers supports the different business functions and security control points. You'd then build this down to your firewalls where you'd have a special zone for outside untrusted management. Next you need to match those prefix lists in route-maps.

Web Security:. I often think about how if 8. When you support many enterprises there is potentially million of dollars worth of traffic traveling over your circuits, so having redundancy with multiple edge connections is important. At this point, you might want to run IBGP between the two border routers. Routing with multiple providers or paths. The Cisco Learning Network. Follow Us. Disclosure statement.
