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
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
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.
/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.
