Virtual Private Networks

• Types of VPNs
• There are three different categories of VPNs
• Remote access VPNs Remote access VPNs allow
  remote users like telecommuters to securely
  access the corporate network wherever and
  whenever they need to.
• Site-to-site VPNs Site-to-site VPNs, or intranet
  VPNs, allow a company to connect its remote sites
  to the corporate backbone securely over a public
  medium like the Internet instead of requiring
  more expensive WAN connections like Frame Relay.
• Extranet VPNs Extranet VPNs allow an
  organizations suppliers, partners, and customers
  to be connected to the corporate network in a
  limited way for business-to-business (B2B)
  communications.

Virtual Private Networks

• four of the most common tunneling protocols
• Layer 2 Forwarding (L2F) Layer 2 Forwarding (L2F)
  is a Cisco-proprietary tunneling protocol, and it
  was their first tunneling protocol created for
  virtual private dial-up networks (VPDNs). VPDN
  allows a device to use a dial-up connection to
  create a secure connection to a corporate
  network. L2F was later replaced by L2TP, which is
  backward compatible with L2F.
• Point-to-Point Tunneling Protocol (PPTP)
  Point-to-Point Tunneling Protocol (PPTP) was
  created by Microsoft to allow the secure transfer
  of data from remote networks to the corporate
  network.
• Layer 2 Tunneling Protocol (L2TP) Layer 2
  Tunneling Protocol (L2TP) was created by Cisco
  and Microsoft to replace L2F and PPTP. L2TP
  merged the capabilities of both L2F and PPTP
  into one tunneling protocol.
• Generic Routing Encapsulation (GRE) Generic
  Routing Encapsulation (GRE) is another
  Cisco-proprietary tunneling protocol. It forms
  virtual point-to-point links, allowing for a
  variety of protocols to be encapsulated in IP
  tunnels.

Classful Routing Overview

• Classful routing protocols do not include the
  subnet mask with the route advertisement.
• Within the same network, consistency of the
  subnet masks is assumed.
• Summary routes are exchanged between foreign
  networks.
• Examples of classful routing protocols
• RIP Version 1 (RIPv1)
• IGRP

25
Classless Routing Overview

• Classless routing protocols include the subnet
  mask with the route advertisement.
• Classless routing protocols support
  variable-length subnet masking (VLSM).
• Summary routes can be manually controlled within
  the network.
• Examples of classless routing protocols
• RIP Version 2 (RIPv2)
• EIGRP
• OSPF
• IS-IS
