Efficient Networks 5800 Business Class Routers: Installation

One of the hallmarks of Efficient Networks 5800 Business Class Routers is their ease of installation. The typical

router installation is simple and goes very quickly. To set up the router initially, the following installation

requirements must be met.

Computer and Network Service Provider (NSP) Requirements

A computer is used to configure and manage the router. The computer can be connected directly to the router with

either the console cable (included with the router) or through an open Ethernet jack (see Figure 2 below). Any

computer that has the following components can be used:

o CD-ROM or DVD drive.

o TCP/IP networking enabled.

o Web browser or terminal emulation software.

o Ethernet or serial port (RS-232) connection. (The Web interface works over TCP/IP. The serial

port/console connection provides detailed configuration of elements not accessible through the Web

interface.)

The network service provider (NSP) provides information on the protocol to be used by the connection. It should be

one of the following:

o Point-to-Point Protocol over ATM (PPP). (Requires a user name and password.)

o Point-to-Point Protocol over Ethernet (PPP) (Requires a user name and password.)

o RFC 1483 (SNAP encapsulation). (Or RFC 1490 if Frame Relay is used in place of ATM.)

o RFC 1483 MER (MAC Encapsulated Routing—requires a WAN gateway IP address).

5800 Configuration Defaults: VPI/VCI

DSL router configurations make use of two numbers called Virtual Path Identifier (VPI) and Virtual Channel

Identifier (VCI). Both terms are related to DSL service deployed over an Asynchronous Transfer Mode (ATM)

network. The VPI indicates the virtual path over which data is routed between the router and the NSP’s network.

Similarly, the VCI identifies the virtual communications channel over which data travels between customer premises

and the NSP. [TBD: Is it important to provide specific default settings for this section, or are we okay with talking

about defaults in a more general way, as we have done here?]

Efficient Networks routers are usually pre-configured with VPI/VCI numbers according to the region in which they

are deployed. If the router isn’t already configured, or if it’s configured for a different NSP, it will be necessary to

obtain these numbers from the NSP and then configure the router with them. In addition, when connecting to

multiple remote sites, additional VPI and VCI numbers are needed from the NSP. These numbers identify remote

destinations and must be unique for each remote.

5800 Configuration Defaults: Encapsulation

A variety of encapsulation options are available in the 5800. As for VPI/VCI, it’s important for the encapsulation

setting to match that of the NSP. Efficient Networks Business Class Routers are generally pre-configured for

specific services, but it’s easy to modify the setting if a change is necessary. The encapsulation methods supported

by the 5800 include:

o Point-to-Point Protocol (PPP)

o PPP Logical Link Control (PPPLLC)

o RFC 1483 (for ATM) or RFC 1490 (for Frame Relay)

o RFC 1483 MER (MAC Encapsulated routing, for ATM) or RFC 1490 MER (for Frame Relay)

o FRF8

o rawIP

Complete information about how these protocols are configured within the Efficient Networks 5800 Business Class

Router is provided on the installation CD included with every router.
