218 IBM 9077 SP Switch Router: Get Connected to the SP Switch
Now it is time to look at the GRF 400:
1. The following screen shot gives you the minimum required data to be put
into /etc/bridged.conf:
Remarks: On the GRF 400, bridging was never defined before, so we
have to create /etc/bridged.conf from a template. Just jump to the end of
the template and type in the data. The
:wq! is there to remind you how to
end editing of the file. We give an n (no) as answer to the last question, as
the ATM ports are already in use and therefore cannot be modified. So we
need to
reboot the GRF, and takes care of the relevant settings anyway.
2. The following changes need to be applied to /etc/grifconfig.conf:
#ga020 10.1.1.2 255.255.255.0 - mtu 9180
#ga0280 10.1.2.2 255.255.255.0 10.1.2.1
bg1 10.1.1.2 255.255.255.0 - mtu 9180
Remarks: The data for the ga020 and ga0280 interface needs to be
commented out and the line for bg1 bridge_group needs to be put in. The
netmask entry is mandatory for bridge_group entries.
3. Finally, bridging requires four entries in the /etc/gratm.conf file:
Traffic_Shape name=high_speed_high_quality \
peak=155000 sustain=155000 burst=2048 qos=high
This following entries remains the same as is the basic configuration:
Interface ga020 traffic_shape=high_speed_high_quality \
bridge_method=llc_encapsulated
Interface ga0280 traffic_shape=high_speed_high_quality \
bridge_method=llc_encapsulated
# bredit
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] y

Signal bridged to effect changes now? [y/n] [n] n
Use ’brsig hup’ to force bridged(8) to re-read the configuration file.
