The output shows that the global link-aggregation load sharing criteria are the source and destination IP
addresses of packets.
Layer 3 Dynamic Aggregation Configuration Example
Network requirements
As shown in Figure 8 :
• Device A and Device B are connected by their Layer 3 Ethernet interfaces GigabitEthernet 0/1
through GigabitEthernet 0/3.
• Configure a Layer 3 dynamic aggregation group on Device A and Device B respectively and
configure IP addresses and subnet masks for the corresponding Layer 3 aggregate interfaces.
• Enable traffic to be load-shared across aggregation group member ports based on source and
destination IP addresses.

Configuration procedure
Step1 Configure Device A
# Create the Layer 3 aggregate interface Route-aggregation 1, configure the link aggregation mode as
dynamic, and configure an IP address and subnet mask for the aggregate interface.
<DeviceA> system-view
[DeviceA] interface route-aggregation 1
[DeviceA-Route-Aggregation1] link-aggregation mode dynamic
[DeviceA-Route-Aggregation1] ip address 192.168.1.1 24
[DeviceA-Route-Aggregation1] quit
# Assign the Layer 3 Ethernet interfaces GigabitEthernet 0/1 through GigabitEthernet 0/3 to
aggregation group 1.
[DeviceA] interface gigabitethernet 0/1
[DeviceA-GigabitEthernet0/1] port link-aggregation group 1
[DeviceA-GigabitEthernet0/1] quit
[DeviceA] interface gigabitethernet 0/2
[DeviceA-GigabitEthernet0/2] port link-aggregation group 1
[DeviceA-GigabitEthernet0/2] quit
[DeviceA] interface gigabitethernet 0/3
[DeviceA-GigabitEthernet0/3] port link-aggregation group 1
[DeviceA-GigabitEthernet0/3] quit
# Configure to use the source and destination IP addresses of packets as the global link-aggregation
load sharing criteria.
[DeviceA] link-aggregation load-sharing mode source-ip destination-ip
Step2 Configure Device B
Configure Device B using the same instructions that you used to as you configure Device A.
