Step 3 Create an HA backup group on each CGN device.
# Create HA backup group 1 on CGN1 and bind it to engine 0 in slot 1.
<CGN1> system-view
[CGN1] service-location 1
[CGN1-service-location-1] location slot 1 engine 0
[CGN1-service-location-1] quit
# Create HA backup group 1 on CGN2 and bind it to engine 0 in slot 1.
<CGN2> system-view
[CGN2] service-location 1
[CGN2-service-location-1] location slot 1 engine 0
[CGN2-service-location-1] quit
Step 4 Create a service instance group on each CGN device.
# Create service instance group 1 on CGN1 and bind it to HA backup group 1.
[CGN1] service-instance-group group1
[CGN1-instance-group-group1] service-location 1
[CGN1-instance-group-group1] quit
# Create service instance group 1 on CGN2 and bind it to HA backup group 1.
[CGN2] service-instance-group group1
[CGN2-instance-group-group1] service-location 1
[CGN2-instance-group-group1] quit
Step 5 Create an NAT instance, and bind the NAT instance to the service instance group on the CGN
device.
# Create an NAT instance on CGN1 and bind it to service instance group 1.
[CGN1] nat instance nat1 id 1
[CGN1-nat-instance-nat1] service-instance-group group1
[CGN1-nat-instance-nat1] port-range 512
[CGN1-nat-instance-nat1] nat address-group address-group1 group-id 1 10.138.1.0
mask 24
[CGN1-nat-instance-nat1] nat outbound any address-group 1
[CGN1-nat-instance-nat1] quit
# Create an NAT instance on CGN2 and bind it to service instance group 1.
[CGN2] nat instance nat1 id 1
[CGN2-nat-instance-nat1] service-instance-group group1
[CGN2-nat-instance-nat1] port-range 512
[CGN2-nat-instance-nat1] nat address-group address-group1 group-id 1 10.138.1.0
mask 24
[CGN2-nat-instance-nat1] nat outbound any address-group 1
[CGN2-nat-instance-nat1] quit
