S9700 Core Routing Switch
Configuration Guide - SPU
When the IPSec service is used, add interfaces on the LPUs and virtual XGE interfaces on the
S9700 switch to VLANs. Configure IP addresses for the VLANIF interfaces to implement Layer
3 forwarding.

Layer 3 flow import with interfaces aggregated
As shown in
Figure
1-4, GE 3/0/0 on an LPU forwards traffic to the SPU. After processing
the traffic, the SPU forwards it to GE 3/0/1. Then GE 3/0/1 forwards the traffic to the LPU.
If two pairs of XGE interfaces on the S9700 and SPU are aggregated into Eth-Trunk
interfaces, add Eth-Trunk 0 and Eth-Trunk 1 to the same VLAN and configure an IP address
for the sub-interface of Eth-Trunk 1, and an IP address for the VLANIF interface. Ensure
that the two IP addresses are on the same network segment.

Layer 3 flow import without interface aggregation
As shown in
Figure
1-5, GE 3/0/0 on an LPU forwards traffic to the SPU. After processing
the traffic, the SPU forwards the traffic to GE 3/0/1. Then GE 3/0/1 forwards the traffic to
the LPU. If interfaces are not aggregated, add XGE 5/0/0 and XGE 0/0/1 to the same VLAN.
Configure an IP address for the sub-interface of XGE 0/0/1 and an IP address for the
VLANIF interface. Ensure that the two IP addresses are on the same network segment.
