Configuring and Managing Routers with Site Manager

Modifying a Router’s Configuration
If you are configuring a new router, you need to modify the initial configuration
file, startup.cfg, which you created using the Quick-Start procedure. (For
information about the Quick-Start procedure, refer to Quick-Starting Routers.)
If you are configuring a router that is already in your network, you need to modify
an existing configuration file, usually named config (config is the default
configuration file).
You can generate a report of the router’s configuration using the Report Generator.
The Report Generator is useful because it converts the binary configuration file to
ASCII format for easy reading, so that you can verify the configuration and
troubleshoot any problems. Refer to Chapter 9 for information about the Report
Generator.
For information about how to enter data in Configuration Manager windows, refer
to Chapter 2.
Configuration Procedure
Table 3-1 outlines the configuration procedure for new and existing routers. This
procedure provides maximum safety when altering a router’s configuration.
Local and remote configuration modes are the safest modes to work in; however,
you can use any mode that suits your situation. For critical applications, when you
must alter how the router is operating, use dynamic mode.
Bay Networks recommends that you always have a config file that you know
works and test any new or modified configuration file under a unique name, for
example, test.cfg. In this way, if the router has a problem starting, you can reset it
and it will restart with the default file, config (refer to Chapter 4 for instructions
about resetting the router).
This procedure is recommended for new and existing routers. In the case of a new
router, although the config file does not represent a complete working
configuration, you do not want to corrupt the config file. If the router should
behave unpredictably, it is easier to recover with the config file.
Specific instructions for each task in T
able 3-1 are located in this and other
chapters. You may want to print or copy this procedure and use it as a checklist as
you complete each task.
