VRRP will bring together a set of routers in LAN. It consists of multiple routers and is similar to a virtual router in respect of function. According to the VLAN interface IP of different network segments, it can be virtualized into multiple virtual routers. Each virtual router has an ID number and up to 255 can be virtualized.

VRRP has the following characteristics:

  1. Virtual router has an IP address, known as the Virtual IP address.  For the host in LAN, it is only required to know the IP address of virtual router, and set it as the address of the next hop of the default route.
  2. Host in the network communicates with the external network through this virtual router.
  3. A router will be selected from the set of routers based on priority to undertake the gateway function. Other routers will be used as backup routers to perform the duties of gateway for the gateway router in case of fault of gateway router, thus to guarantee uninterrupted communication between the host and external network.

Monitor interface function of VRRP better expands backup function: the backup function can be offered when interface of a certain router has fault or other interfaces of the router are unavailable.

When interface connected with the uplink is at the state of Down or Removed, the router actively reduces its priority so that the priority of other routers in the backup group is higher and thus the router with highest priority becomes the gateway for the transmission task.

From navigation tree, select "Network >>VRRP" menu, then enter “VRRP” page.

3.3 SERVICE

3.3.1 DHCP service

DHCP adopts Client/Server communication mode. Client sends configuration request to Server which feeds back corresponding configuration information, including distributed IP address to the Client to achieve the dynamic configuration of IP address and other information.

  1. The duty of DHCP Server is to distribute IP address when Workstation logs on and ensure each workstation is supplied with different IP address. DHCP Server has simplified some network management tasks requiring manual operations before to the largest extent.
  2. As DHCP Client, the device receives the IP address distributed by DHCP server after logging in the DHCP server, so the Ethernet interface of the device needs to be configured into an automatic mode.

To enable the DHCP server, find the navigation tree, select Services >> DHCP Service, then enter “DHCP Service” page.

3.3.4 DDNS

DDNS maps user's dynamic IP address to a fixed DNS service. When the user connects to the network, the client program will pass the host’s dynamic IP address to the server program on the service provider’s host through information passing. The server program is responsible for providing DNS service and realizing dynamic DNS. It means that DDNS captures user's each change of IP address and matches it with the domain name, so that other Internet users can communicate through the domain name. What end customers have to remember is the domain name assigned by the dynamic domain name registrar, regardless of how it is achieved.

DDNS serves as a client tool of DDNS and is required to coordinate with DDNS Server. Before the application of this function, a domain name shall be applied for and registered on a proper website such as www. 3322. org. 

InRouter300-S DDNS service types include QDNS (3322)-Dynamic, QDNS(3322)-Static, DynDNS-Dynamic, DynDNS-Static, DynDNS-Custom and No-IP.com.

3.3.6 SNMP

Network devices are usually sparsely-located on a network. It is time-consuming for the administrator to configure and manage these network devices on site. In addition, if these devices are from different vendors, each of which provides a suite of independent management interfaces (for example, different command line interfaces), the workload of configuring the devices in batches is huge. In this situation, traditional manual configuration method has the deficiencies of high cost and low efficiency. The network administrator can use the Simple Network Management Protocol (SNMP) to remotely configure and manage the devices and perform real-time monitoring on them. 

Figure 3-3-6 SNMP Topology

To run the SNMP protocol on a network, configure the NMS program on the management side and SNMP agent on the managed devices.

By using SNMP:

  1. The NMS can collect status information of the managed devices anytime and anywhere through agents and remotely control these devices.
  2. The agents can promptly report the current status and faults of managed devices to the NMS.

Currently, the SNMP agents support SNMPv1, SNMPv2c and SNMPv3. SNMPv1 and SNMPv2c use community names for authentication; SNMPv3 uses user names and passwords for authentication. Click "Service>>SNMP" menu to configure.

Table 3-3-6-1 SNMPv1 and SNMPv2c Parameters

Parameters

Description

Default

Enable

Enable/disable the SNMP function.

Disabled

Version

Set the version of the SNMP protocol used to manage the router. The versions of SNMPv1, v2c, and v3 are available.

SNMPv1 is applicable to small-sized networks with simple networking and low security requirements, or the secure and stable small networks, such as campus networks and small enterprise networks.

SNMPv2c is applicable to the medium- and large-sized networks with low security requirements, or with good security (for example, VPNs) but running many services, which may lead to traffic congestion.

SNMPv3 is applicable to networks of various sizes, especially the networks that have strict security requirements and can be managed only by authorized network administrators. For example, SNMPv3 can be used if data between the NMS and managed device is transmitted over a public network.

3.6 VPN

VPN is for building a private dedicated network on a public network via the Internet. 'Virtuality" is a logical network.

Two Basic Features of VPN:

  1. Private: the resources of VPN are unavailable to unauthorized VPN users on the internet; VPN can ensure and protect its internal information from external intrusion.
  2. Virtual: the communication among VPN users is realized via public network which, meanwhile can be used by unauthorized VPN users so that what VPN users obtained is only a logistic private network.  This public network is regarded as VPN Backbone.

Build a credible and secure link by connecting remote users, company branches, partners to the network of the headquarters via VPN so as to realize secure transmission of data. 

It is shown in the figure below:

Fundamental Principle of VPN

The fundamental principle of VPN indicates to enclose VPN message into tunnel with tunneling technology and to establish a private data transmission channel utilizing VPN Backbone so as to realize the transparent message transmission.

Tunneling technology encloses the other protocol message with one protocol. Also, encapsulation protocol itself can be enclosed or carried by other encapsulation protocols. To the users, tunnel is logical extension of PSTN/link of ISDN, which is similar to the operation of actual physical link.

VPN settings include IPSec settings, IPSec tunnels, GRE tunnels, L2TP client, PPTP client, OpenVPN, OpenVPN Advanced and certificate management. 

3.6.1 IPSec Settings

A majority of data contents are Plaintext Transmission on the Internet, which has many potential dangers such as password and bank account information stolen and tampered, user identity imitated, suffering from malicious network attack, etc. After disposal of IPSec on the network, it can protect data transmission and reduce risk of information disclosure.

IPSec is a group of open network security protocol made by IETF, which can ensure the security of data transmission between two parties on the Internet via data origin authentication, data encryption, data integrity and anti-replay function on the IP level. It is able to reduce the risk of disclosure and guarantee data integrity and confidentiality and well as maintain security of service transmission of users.

IPSec, including AH, ESP and IKE, can protect one and more date flows between hosts, between host and gateway, and between gateways. The security protocols of AH and ESP can ensure security and IKE is used for cipher code exchange.

IPSec can establish bidirectional Security Alliance on the IPSec peer pairs to form a secure and interworking IPSec tunnel and to realize the secure transmission of data on the Internet.

From navigation tree, select VPN>>IPSec Settings, then enter “IPSec Settings” page.

The security level of three encryption algorithms ranks successively: AES, 3DES, DES. The implementation mechanism of encryption algorithm with stricter security is complex and slow arithmetic speed. DES algorithm can satisfy the ordinary safety requirements.

3.6.3 GRE Tunnels

Generic Route Encapsulation (GRE) defines the encapsulation of any other network layer protocol on a network layer protocol. GRE could be used as the L3TP of VPN to provide a transparent transmission channel for VPN data. In simple terms, GRE is a tunneling technology which provides a channel through which encapsulated data message could be transmitted and encapsulation and decapsulation could be realized at both ends. GRE tunnel application networking shown as the following figure:


Along with the extensive application of IPv4, to have messages from some network layer protocol transmitted on IPv4 network, those messages could by encapsulated by GRE to solve the transmission problems between different networks.

In following circumstances GRE tunnel transmission is applied:

  1. GRE tunnel could transmit multicast data packets as if it were a true network interface.  Single use of IPSec cannot achieve the encryption of multicast.
  2. A certain protocol adopted cannot be routed.
  1. A network of different IP address shall be required to connect other two similar networks.

GRE application example: combined with IPSec to protect multicast data

GRE can encapsulate and transmit multicast data in GRE tunnel, but IPSec, currently, could only carry out encryption protection against unicast data. In case of multicast data requiring to be transmitted in IPSec tunnel, a GRE tunnel could be established first for GRE encapsulation of multicast data and then IPSec encryption of encapsulated message so as to achieve the encryption transmission of multicast data in IPSec tunnel. As shown below:


From navigation tree, select VPN>>GRE Tunnels and enter "GRE Tunnels".

3.6.4 L2TP Client

L2TP, one of VPDN TPs, has expanded the applications of PPP, known as a very important VPN technology for remote dial-in user to access the network of enterprise headquarters.

L2TP, through dial-up network (PSTN/ISDN), based on negotiation of PPP, and could establish a tunnel between enterprise branches and enterprise headquarters so that remote user has access to the network of enterprise headquarters. PPPoE is applicable in L2TP. Through the connection of Ethernet and Internet, a L2TP tunnel between remote mobile officers and enterprise headquarters could be established.

L2TP-Layer 2 Tunnel Protocol encapsulates private data from user network at the head of L2 PPP. No encryption mechanism is available, thus IPSes is required to ensure safety.

Main Purpose: branches in other places and employees on a business trip could access to the network of enterprise headquarter through a virtual tunnel by public network remotely.

Typical L2TP network diagram is shown below:

3.6.6 OpenVPN

Single point participating in the establishment of VPN is allowed to carry out ID verification by preset private key, third-party certificate or username/password. OpenSSL encryption library and SSLv3/TLSv1 protocol are massively used.

In OpenVPN, if a user needs to access to a remote virtual address (address family matching virtual network card), then OS will send the data packet (TUN mode) or data frame (TAP mode) to the visual network card through routing mechanism.  Upon the reception, service program will receive and process those data and send them out through outer net by SOCKET, owing to which, the remote service program will receive those data and carry out processing, then send them to the virtual network card, then application software receive and accomplish a complete unidirectional transmission, vice versa.
