Configuration of IP-Forwarding Media Cards 149
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.
