Hybrid IPSec-MPLS VPNs: What They Are and When They Make Sense. In a recent post I wrote about MPLS VPNs, and how they’re a step up from VPNs based on IPSec.
That post ended with this paragraph: It’s also possible to use a mix of both IPSec and MPLS VPNs in a hybrid configuration. Smaller sites, for example, may feed in to the MPLS VPN via IPSec connections, enabling companies to use the service that makes the most sense for each location. In this post I thought I’d dive a little deeper into what a hybrid VPN is and the circumstances where it makes the most sense. Enterprise Branch Security Design Guide. Brocade%20remote%20connection.

Providing Secure Communication Between Sites Using VPN CloudHub - Amazon Virtual Private Cloud. If you have multiple VPN connections, you can provide secure communication between sites using the AWS VPN CloudHub.
The VPN CloudHub operates on a simple hub-and-spoke model that you can use with or without a VPC. This design is suitable for customers with multiple branch offices and existing Internet connections who'd like to implement a convenient, potentially low-cost hub-and-spoke model for primary or backup connectivity between these remote offices. The following diagram shows the VPN CloudHub architecture, with blue dashed lines indicating network traffic between remote sites being routed over their VPN connections. To use the AWS VPN CloudHub, you must create a virtual private gateway with multiple customer gateways, each with unique Border Gateway Protocol (BGP) Autonomous System Numbers (ASNs). Customer gateways advertise the appropriate routes (BGP prefixes) over their VPN connections. When using an AWS VPN CloudHub, you pay typical Amazon VPC VPN connection rates.
SDN Security Attack Vectors and SDN Hardening. As enterprises look to adopt Software Defined Networking (SDN), the top of mind issue is the concern for security.
Enterprises want to know how SDN products will assure them that their applications, data and infrastructure will not be vulnerable. With the introduction of SDN, new strategies for securing the control plane traffic are needed. This article will review the attack vectors of SDN systems and share ways to secure the SDN-enabled virtualized network infrastructure. This article will then discuss the methods currently being considered to secure SDN deployments. 1. Software-Defined Networking (SDN) is an approach to networking that separates the control plane from the forwarding plane to support virtualization. Error.

Why MPLS VPNs are a step up from traditional VPNs. While the Internet offers a relatively inexpensive way to connect your various business locations and foster communications with employees, partners and even customers, it is also inherently insecure.
For that reason, companies have for years been using virtual private networks (VPNs) to essentially carve a secure tunnel through the Internet. While VPNs based on IPSec dominated the landscape early on, today customers have a choice between VPNs based on IPSec or MPLS. This post will try to shed light on why, for many business use cases, the MPLS version is a better option.
Public vs. private network For starters, IPSec VPNs run across the public Internet. MPLS VPNs, on the other hand, run across a single carrier’s private MPLS network, not the public Internet.

Cisco SPA8800 IP Telephony Gateway with 4 FXS and 4 FXO Ports. Click the arrow to open and close the My Cisco Menu.
The Cisco SPA8800 IP Telephony Gateway is a multipurpose solution that small businesses can use to connect an on-premise IP private branch exchange (PBX) system to the public switched telephone network (PSTN), or connect a legacy time-division multiplexing (TDM) PBX or key system to voice-over-IP (VoIP) services. The Cisco SPA8800 provides a combination of four Foreign eXchange Office (FXO) and four Foreign eXchange Subscriber (FXS) ports to connect to existing analog phones, which helps protect and extend your existing communications equipment investments, too.
The Cisco SPA8800 also has the capability to be configured as an FXO gateway for an Asterisk Open Source PBX providing a versatile solution when conditions favor an external device. Additional features of the Cisco SPA8800 include: User Guides, Release Notes, and Support Information. Phone Home for Free – A Customer Story « Cisco Meraki Blog. Note: The full case study will be featured on our website soon, but here is a sneak peek into how they are using VOIP and the automatic failover mechanisms built into Meraki products to support their business operation.
Based in Perth, Australia, Cash Converters is a pawnbroking franchise company and retailer, with over 700 stores in 21 countries that specialize in the sale of second-hand goods. All of their stores operate on an online point of sale system, making Internet connectivity critical. “We are 100% dependent on the Internet at all times,” Duncalf stressed. To ensure a secure, reliable, and scalable network, each Australian Cash Converters store is equipped with a full Meraki stack, consisting of a Cisco Meraki MX security appliance, MS switch, and MR wireless access point.
The stores use a fully-redundant MPLS network, with traffic spanned across multiple VLANs.

EUI-64 in IPv6. By stretch | Monday, August 4, 2008 at 2:13 a.m.
UTC One of IPv6's key benefits over IPv4 is its capability for automatic interface addressing. By implementing the IEEE's 64-bit Extended Unique Identifier (EUI-64) format, a host can automatically assign itself a unique 64-bit IPv6 interface identifier without the need for manual configuration or DHCP. This is accomplished on Ethernet interfaces by referencing the already unique 48-bit MAC address, and reformatting that value to match the EUI-64 specification.
RFC 2373 dictates the conversion process, which can be described as having two steps. Why 0xFFFE? The second step is to invert the universal/local (U/L) flag (bit 7) in the OUI portion of the address. Again, you're probably wondering why this is done.

This document will outline basic negotiation and configuration for crypto-map-based IPsec VPN configuration.
This document is intended as an introduction to certain aspects of IKE and IPsec, it WILL contain certain simplifications and colloquialisms. IPsec is a standard based security architecture for IP hence IP-sec. IKE (Internet Key Exchange) is one of the ways to negotiate IPsec Security Associations (SAs), in particular case ISAKMP (implementation of IKE) is what Cisco uses. Currently two versions of IKE exist: IKE version 1 (IKEv1) - the more common and older, widely deployed. IPsec Troubleshooting: Understanding and Using debug Commands.
