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 -v
to make the changes
permanent. Reboot the GRF.
Note: According to GRF Configuration Guide 1.4, GA22-7366, just
grconfig
or
grreset
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 -i
is needed.
2. Check for correct bridge interface creation on GRF 1600:
