IBM 9077 manual Bridgegroup bg0 Port gf000 gf001 gf002 gf003

bridge_group bg0 {

port gf000 gf001 gf002 gf003;

};

This is the simplest bridge definition that worked in our scenario. Many additional parameters can be set. See Section 4.6.9.3, “Editing Utility – Bredit” on page 146 for further details.

•Assign an IP address:

Open /etc/grifconfig.conf. Comment out all former FDDI interface definitions by inserting a # at the beginning of the respective lines. Define the new bridge group and assign an IP address that is in the same subnet as all four FDDI backbones:

bg0 10.10.1.13 255.255.255.0 - mtu 4352

Save /etc/grifconfig.conf. Issue grwrite -vto make the changes permanent. Reboot the GRF.

Note: According to GRF Configuration Guide 1.4, GA22-7366, just grconfig or grreset <slot_number> should completely disable the now commented FDDI interfaces and enable the bridge setting. In the current Ascend Embedded/OS Version 1.4.6.4, this does not work (maybe in later releases). The new bridge settings are enabled but the commented interface definitions are not removed from the kernel. In this case, you will receive error messages because the bridge daemon cannot add the interfaces to the bridge group as long as IP addresses are assigned to them. Therefore, reboot -iis needed.

2. Check for correct bridge interface creation on GRF 1600:
