Q:

What are the typical three different categories of VPNs?

Answer

The following are the different types of VPNs :


PPTP ( Point to Point Tunnel protocol ) VPN : Most commonly used VPN. PPTP is a method for implementing virtual private networks. PPTP uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets.


Site-to-Site VPN : Site-to-site VPN is a type of VPN connection that is created between two separate locations. Site-to-site VPN can be intranet based or extranet based. 


Intranet-based site-to-site VPN is created between an organization's propriety networks, while extranet-based site-to-site VPN is used for connecting with external partner networks or an intranet.


L2TP ( Layer Two Tunneling Protoco) VPN : L2TP is an extension of the Point-to-Point Tunneling Protocol (PPTP) used by an Internet service provider (ISP) to enable the operation of a virtual private network over the Internet.


IPsec (Internet Protocol Security) : IPsec is a framework for a set of protocols for security at the network or packet processing layer of network communication.


SSL (Secure Sockets Layer) VPN : SSL  is a form of VPN that can be used with a standard Web browser. In contrast to the traditional Internet Protocol Security (IPsec) VPN, an SSL VPN does not require the installation of specialized client software on the end user's computer. 


MPLS (Multiprotocol Label Switching) VPN : MPLS is a protocol for speeding up and shaping network traffic flows. 


Hybrid VPN : A hybrid VPN combines Multiprotocol Label Switching (MPLS) and Internet protocol security (IPsec)-based VPNs.

Q:

How should a router that is being used in a Frame Relay  network be configured to keep split horizon issues from preventing routing updates

A) Configure a seperate subinterface for each PVC with a unique DLCI and subnet assigned to the subinterface B) Combine multiple Frame Relay circuits as a point-to-point line to support multicast and broadcast traffic
C) Configure many subinterfaces in the same subnet D) Configure a single subinterface to establish multiple PVC connections to multiple remote router interfaces.
 
Answer & Explanation Answer: A) Configure a seperate subinterface for each PVC with a unique DLCI and subnet assigned to the subinterface

Explanation:

If you have a serial port configured with multiple DLCIs connected to multiple remote sites, split horizon rules stop route updates received on an interface from being sent out the same interface. By creating subinterfaces for each PVC, you can avoid the split horizon issues when using Frame Relay.
