If you are going to configure an encapsulated bridge on an ATM circuit, edit the /etc/gratm.conf file to create a PVC on the ATM OC-3c logical interface.

5. Specify ARP service in the /etc/grarp.conf file, if needed.

4.6.11.1 Starting Bridged

The grstart program regularly checks for the presence of /etc/bridged.conf and starts the bridged daemon when the file is found.

In the UNIX shell, copy the template for the bridging configuration file to /etc/bridged.conf:

# cp /etc/bridged.conf.template /etc/bridged.conf

You will see this message:

# Jun 14 23:56:53 grf16 root: grstart: starting bridged.

Now you can use the bredit command to open bridged.conf and edit it:

#bredit

#NetStar $Id

#Configuration file for Bridge Daemon (bridged).

#Note: bridged will not start if it finds an error while

#trying to parse this file. Use the "-d" option on the

#command line with bridged to find proximity of the offending

#line.

#

If you have not already copied /etc/bridged.conf, or if grstart cannot find the file, you see this message:

Could not find default config file : /etc/bridged.conf

This seems to be the first time bridged is being configured. Do you want to use the template configuration file ? [y/n] [n]

If you respond “yes” ( y) to the bredit query, the file is opened for you in the UNIX vi editor. Comments in the file describe how to configure a group and its members, and define the bridging options and any defaults.

Exit the file with the vi command, :q. You do not need to write the file, bredit will do that.
