Unpacking the Router

This section outlines the procedure for unpacking, configuring, installing and testing your ImageStream router. It is assumed that the installer is familiar with the basic layout and operation of electronic equipment, routers, and cables.
Though an ImageStream router is shipped in a sturdy cardboard box with foam padding, it may still be damaged in shipping. We suggest that each box and its contents be examined for visual damage. If your shipment arrives damaged, incomplete, or incorrect, contact ImageStream Internet Solutions, Inc. immediately.
The following items are typically shipped in a router box. However, the packing list should be reviewed to verify the completeness of the shipment:
Base router chassis
  • Router chassis
  • Power cable(s)
  • Quick start guide
  • Terms and Conditions of Sale and Warranty Notice
Cards without integrated CSU/DSUs
  • WAN card with RS232, EIA-530 or V.35 interface options
  • RS232, RS449, EIA530 or V.35 Adapter Cable (if ordered)
Cards with integrated CSU/DSUs
  • WAN card with CSU and RS232, EIA-530 or V.35 interface options (if any)
  • RS232, RS449, EIA530 or V.35 Adapter Cable (if ordered)
  • RJ48 Loop Back Plug (if ordered)
The Ethernet (100BaseTX/10BaseT), Token Ring, serial and console ports contain safety extra-low voltage (SELV) circuits. T1, 56 Kbps (DDS), BRI and PRI circuits are telephone-network voltage (TNV) circuits. Avoid connecting SELV circuits to TNV circuit equipment, such as WAN cards with integrated CSU/DSUs, as this can cause damage to the equipment.

Router Software

All ImageStream routers are shipped with the ImageStream Linux router software distribution. This wiki contains detailed information on the configuration and application of the software. ImageStream Linux contains the following standard embedded packages:
Base-binaries - Includes all basic Linux binary utilities and devices. This package includes command line utilities such as vi, pico and rm as well as the tty login devices and process ID storage directories.
Base-libraries - Includes all shared libraries required by Enterprise Linux. This package includes curses libraries, terminal information and basic cryptography libraries.

Failsafe-Configuration - This package and associated directory contains basic information required to boot the router. Basic entries in the /etc configuration directory and startup scripts are included in the package. Coupled with the Failsafe directory stored in the router's nonvolatile (Flash) RAM, this package can be used to boot the router with a simple default configuration in the event of problems with the main configuration or if the router password is lost.
OpenSSH - This package contains the command line utilities and libraries for the open source secure shell (SSH) program. This package is used to support secure connections to the router over a network connection.

Pre-Configuration Planning

Before the ImageStream router can be used to connect wide area networks (WANs), you must install the hardware using the instructions in the installation guide for your system. This configuration guide is designed to introduce the most common configuration options available for ImageStream products. Review this material before you configure your router and, if possible, answer the following questions:
  • What general configuration do you want to implement?
  • Will you be using internal or external CSU/DSU's with your high-speed lines?
  • Will your high-speed lines use ATM, Frame Relay, HDLC, PPP or ISDN encapsulation?
  • Do you need dial-on-demand for ISDN backup connections?
  • Do you need to bond multiple circuits or virtual circuits together?
  • Do you want packet filtering or firewalling for Internet or other connections?
  • Have you obtained a sufficient number of network addresses, or do you want to use the network address translation (NAT) software?
  • Do you need to bridge multiple segments together?
  • Do you want to enable Simple Network Management Protocol (SNMP) for network monitoring?

Pre-Installation Information

Have the following information on hand before you start
Parameter Where to find it Description
Local IP Address Line Provider The local IP address will be the address for the specific link/port ("numbered link") or primary Ethernet address "unnumbered link") of your router.
Remote IP Address Line Provider The remote IP address will be the address for the specific link/port ("numbered link") or primary Ethernet address ("Unnumbered link") of the other router on the other end of the link.
Clock Source Line Provider The clock source will either be internal (provided by the WAN card or the integrated CSU) or external (provided by the CSU/DSU or by the line provider).
Line Encoding/Framing Line Provider If you have a card with an integrated CSU/DSU you will need to know these values. The normal encoding values will be B8ZS or AMI and normal framing values are Extended Super Frame (ESF) or Super Frame (SF or D4).
DLCI Number (Frame Relay Only) Line Provider Used to establish virutal circuits across frame relay nertworks to remote router.


Basic Configuration Tips

The exact configuration steps you follow depend upon the hardware you are installing and your network configuration. However, the following general configuration steps are the same for all ImageStream products:
1. Install the ImageStream hardware as described in the Quick Start Guide shipped with your router. Additional information on configuring the router password, IP address and other basic information is below.
2. Boot the system and log in with the administrative password. You can configure the ImageStream router from a keyboard and monitor (on supported systems), a terminal attached to the console port, by an administrative telnet or ssh session, or by a network connection.
3. Configure the global settings. Global settings are described in Chapter 4, "Configuring Global Settings: the AAA and Global Configuration Menus."
4. Configure the Ethernet or Token Ring settings. Ethernet and Token Ring settings are described in Chapter 5, "Configuring a LAN Interface."
5. Configure the synchronous serial WAN port(s), if available. Synchronous serial WAN interface settings are described in Chapter 7, "Configuring a Synchronous WAN Interface."
6. Configure the integrated CSU/DSU connection(s), if available. OC-12, OC-3, ATM DS3, ATM E3, T1, and E1 connection configuration is described in Chapter 8, "Configuring an Integrated CSU/DSU WAN Interface." ISDN BRI connection configuration is covered in Chapter 11, "Configuring an ISDN BRI Interface."
7. Configure the ATM connection(s), if available. ATM OC-12, OC-3, DS3, E3, T1, and E1 connection configuration is described in Chapter 9, "Configuring an ATM Interface."
8. Configure the Frame Relay connection(s), if available. Frame Relay DS3, E3, T1, and E1 connection configuration is described in Chapter 10, "Configuring a Frame Relay Interface."
9. Configure ISDN BRI connection(s), if available. Basic Rate ISDN connection configuration is described in Chapter 11, "Configuring an ISDN BRI Interface."
10. Configure iptables, if you are using it. iptables is Linux's open source traffic filtering and firewalling mechanism for networks. iptables configuration is described in Chapter 20, "Configuring Services: Firewall Menu."
11. Configure Differentiated Services/Quality of Service, if you are using it. ImageStream uses the IETF-standard DiffServ implementation for bandwidth/rate limiting and quality of service for networks. Configuration of these tools is described in Chapter 13, "Configuring Bonder For Load Balancing And Aggregation," Chapter 17, "Configuring Rate Limiting Within SAND" and in Chapter 18, "Configuring Services: Quality of Service Menu."
12. Configure RIP, if you are using this protocol. RIP is described in the GateD Configuration Manual.
13. Configure OSPF, if you are using this protocol. OSPF is described in the GateD Configuration Manual.
14. Configure ISIS, if you are using this protocol. ISIS is described in the GateD Configuration Manual.
15. Configure BGP, if you are using this protocol. BGP is described in the GateD Configuration Manual.
16. Configure other router services, if necessary. Additional router services such as SNMP, SSH, serial console.
17. Troubleshoot your configuration, if necessary, and back it up. See the Chapter 28, "Troubleshooting" for instructions. Once you have correctly configured all the settings necessary for your circumstances, your ImageStream router is ready to provide communication service and routing for your network.
