The output above 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 39 :
• Configure a Layer 3 dynamic link aggregation group on both Device A and Device B 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
1. Configure Device A:
# Create 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 Layer 3 Ethernet interfaces GigabitEthernet 3/0/1 through GigabitEthernet 3/0/3 to
aggregation group 1.
[DeviceA] interface Gigabitethernet 3/0/1
[DeviceA-Gigabitethernet3/0/1] port link-aggregation group 1
[DeviceA-Gigabitethernet3/0/1] quit
[DeviceA] interface Gigabitethernet 3/0/2
[DeviceA-Gigabitethernet3/0/2] port link-aggregation group 1
[DeviceA-Gigabitethernet3/0/2] quit
[DeviceA] interface Gigabitethernet 3/0/3
[DeviceA-Gigabitethernet3/0/3] port link-aggregation group 1
[DeviceA-Gigabitethernet3/0/3] 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
2. Configure Device B in the same way Device A is configured.
Verifying the configuration
# Display the summary information about all aggregation groups on Device A.
[DeviceA] display link-aggregation summary
