Multiple RS/6000 SPs and Multiple GRFs 217
Router, so there was no technical reason for it. The
:wq! in the screen shot
is there to remind you how to end editing of the file, and 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 this
takes care of the relevant settings anyway. See Section 4.6.9.3, “Editing
Utility – Bredit” on page 146 for more information.
2. The following changes need to be applied to /etc/grifconfig.conf:
#ga010 10.1.1.1 255.255.255.0 - mtu 9180
#ga0180 10.1.2.1 255.255.255.0 - mtu 9180
bg1 10.1.1.1 255.255.255.0 - mtu 9180
Remarks
: The data for the ga010 and ga0180 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 these entries in the /etc/gratm.conf file:
Traffic_Shape name=high_speed_high_quality \
peak=155000 sustain=155000 burst=2048 qos=high
This entry remains the same as in the basic configuration:
Interface ga010 traffic_shape=high_speed_high_quality \
bridge_method=llc_encapsulated
Interface ga0180 traffic_shape=high_speed_high_quality \
bridge_method=llc_encapsulated
These two lines were changed from the basic configuration!
PVC ga010 0/132 proto=llc,bridging
PVC ga0180 0/134 proto=llc,bridging
Because the GRF supports inverse ATM ARP (InATMARP), there is no need
to put any entries in /etc/grarp.conf.
The file /etc/grroute.conf also remains unchanged:
192.168.13.0 255.255.255.0 10.1.1.2
If there is no such entry in /etc/grroute.conf, the following command must be
run on GRF 1600:
route add -net 192.168.13.0 -netmask 255.255.255.0 -mtu 9180 10.1.1.2
