Overview/Description
Dynamic Multipoint Virtual Private Networks (DMVPNs) are a Cisco IOS Software feature that simplifies the deployment of large hub-and-spoke, partially meshed, and fully meshed virtual private networks (VPNs). In this lesson, you will learn to integrate multipoint Generic Routing Encapsulation (mGRE) with Next Hop Resolution Protocol (NHRP) and IP Security (IPSec) to deploy DMVPN on hub-and-spoke devices. After configuring all required parameters, you will verify proper DMVPN operation and learn how to troubleshoot common DMVPN issues.

Overview/Description
Cisco IOS Network Address Translation (NAT) and Port Address Translation (PAT) are mechanisms that you can use to conserve registered IP version 4 (IPv4) addresses in large networks, resolve overlapping addressing scenarios, and simplify IPv4 address management tasks. NAT and PAT translate IPv4 addresses within private internal networks to legal IPv4 addresses for transport over public external networks, such as the Internet, without requiring a registered subnet address. Incoming traffic is translated back for delivery within the inside network. This translation of IPv4...
Overview/Description
A basic Cisco IOS Software Secure Sockets Layer (SSL) virtual private network (VPN) solution allows users flexible client-based or clientless access to sensitive resources over a remote access VPN gateway that is implemented on a Cisco Integrated Services Router (ISR) device running Cisco IOS Software. A basic SSL VPN employs user authentication with usernames and static passwords and a single access control policy that applies to all users. This course enables you to configure, verify, and troubleshoot a basic client-based and clientless SSL VPN solution on a Cisco ISR....
Overview/Description
You can configure IP Security (IPSec) virtual private networks (VPNs) with various types of authentication, which often limit its scalability with regard to performance and configuration manageability. A simple method, such as using pre-shared keys (PSKs), requires you to share a secret between each pair of VPN peers. A more scalable authentication method incorporates the public key infrastructure (PKI) for authentication purposes. This course discusses the process of configuring an IPSec site-to-site VPN using PKI-facilitated peer authentication.

Overview/Description
Building a highly available virtual private network (VPN) network involves protecting it against expected failures, and enabling the VPN network to heal itself in a reasonable amount of time. Organizations have different uptime requirements for their networks. Frequently, when migrating from a traditional circuit-based WAN network, which had high availability mechanisms in place (backup dial interfaces, backup routers), the need to provide the same or better functionality in a VPN is paramount. Fully meshed virtual private networks (VPNs) present a scalability and...
Overview/Description
The network infrastructure is one of the foundation elements of enterprise IT infrastructures and is a critical business asset of telecommunications service providers. A compromise of the network infrastructure or its individual components can have far-reaching consequences that can significantly increase risk to enterprise and service provider business processes. Cisco IOS Network Foundation Protection (NFP) provides a strategy for network infrastructure protection by using Cisco IOS Software security features. This course describes the threats against the network...
Overview/Description
Remote access virtual private network (VPN) technologies allow mobile workers to access sensitive resources over untrusted networks by using modern transmission protection and access authorization technologies. Cisco IOS Software provides a rich set of remote access VPN features that cover a wide range of common enterprise use cases. This course introduces and compares remote access VPN technologies and access methods.

Network professionals responsible for securing and managing their network infrastructures who have CCNA certification, CCNA Security...
Overview/Description
An IP Security (IPSec) virtual private network (VPN) is a VPN that you deploy on a shared infrastructure using IPSec transmission protection technology. You can use site-to-site IPSec VPNs as an alternative to a WAN infrastructure to replace or augment existing private networks that interconnect enterprise sites and use leased-line or enterprise-owned Frame Relay and ATM networks. IPSec VPNs do not inherently change WAN requirements, such as support for multiple WAN Layer 2 protocols, high reliability, and extensive scalability, but instead meet these requirements more...
Overview/Description
A basic Cisco AnyConnect full-tunnel Secure Sockets Layer (SSL) VPN provides users with flexible client-based access to sensitive resources over a remote access VPN gateway, which is implemented on the Cisco ASA adaptive Security Appliance. A basic Cisco AnyConnect full-tunnel SSL VPN solution uses usernames and passwords to provide basic user authentication. In addition, the Cisco ASA Security Appliance provides IP address assignment to the full-tunnel client and uses a basic access control policy. This course discusses how to configure, verify, and troubleshoot a basic...
Overview/Description
The Cisco ASA adaptive security appliance supports remote access IP Security (IPsec) VPNs that you can manage using the Cisco Easy VPN solution. Remote access IPsec VPNs protect traffic between mobile workers and a central site. This course describes how to deploy remote access IPsec VPNs, including preshared authentication, certificate-based authentication, and advanced public key infrastructure (PKI) integration. Remote access deployments that use the Cisco VPN Client and the Cisco AnyConnect 3.0 Client for IPsec connections are also described. Cisco VPN Client is...
