4.6.11 Configuration File and Profile Overview

When a new GRF system is installed or a site upgrades to a bridging software release, the /etc/bridged.conf file does not exist. The bridging daemon, bridged, will not start without this file. The grstart program periodically checks to see if the /etc/bridged.conf file exists; when it finds the file, grstart then starts bridged. The following are the steps to configure bridging. For more information, refer to GRF Configuration Guide 1.4, GA22-7366.

1.Create /etc/bridged.conf.

A template file for /etc/bridged.conf is provided in /etc/bridged.conf.template. Copy the template file into /etc/bridged.conf.

2.Create bridge groups in /etc/bridged.conf

Run bredit to create and name the bridge groups, and assign bridging parameters to each.

3.Assign an IP address to each bridge group.

Edit /etc/grifconfig.conf to identify each bridge group by assigning:

An IP address

The GRF interface name

A netmask, required

A destination or broadcast address, as required

An MTU value, if needed

4.Create ATM OC-3c PVCs for encapsulated bridges.
