Layer 3 aggregation load sharing configuration example

Network requirements

As shown in Figure 6:

• Configure Layer 3 static aggregation groups 1 and 2 on Device A and Device B, respectively.

• Configure IP addresses and subnet masks for the corresponding Layer 3 aggregate interfaces.

• Configure link aggregation group 1 to perform load sharing based on source IP address.

• Configure link aggregation group 2 to perform load sharing based on destination IP address.

Configuration procedure

1. Configure Device A:

# Create Layer 3 aggregate interface Route-Aggregation 1.

<DeviceA> system-view

[DeviceA] interface route-aggregation 1

# Configure Layer 3 aggregate interface Route-Aggregation 1 to perform load sharing based on

source IP address.

[DeviceA-Route-Aggregation1] link-aggregation load-sharing mode source-ip

# Configure an IP address and subnet mask for Layer 3 aggregate interface Route-Aggregation 1.

[DeviceA-Route-Aggregation1] ip address 192.168.1.1 24

[DeviceA-Route-Aggregation1] quit

# Assign Layer 3 Ethernet interfaces GigabitEthernet 2/1/1 and GigabitEthernet 2/1/2 to

aggregation group 1.

[DeviceA] interface gigabitethernet 2/1/1

[DeviceA-GigabitEthernet2/1/1] port link-aggregation group 1

[DeviceA-GigabitEthernet2/1/1] quit

[DeviceA] interface gigabitethernet 2/1/2

[DeviceA-GigabitEthernet2/1/2] port link-aggregation group 1

[DeviceA-GigabitEthernet2/1/2] quit

# Create Layer 3 aggregate interface Route-Aggregation 2.

[DeviceA] interface route-aggregation 2

# Configure Layer 3 aggregate interface Route-Aggregation 2 to perform load sharing based on

destination IP address.

[DeviceA-Route-Aggregation2] link-aggregation load-sharing mode destination-ip

# Configure an IP address and subnet mask for Layer 3 aggregate interface Route-Aggregation 2.

[DeviceA-Route-Aggregation2] ip address 192.168.2.1 24

[DeviceA-Route-Aggregation2] quit

# Assign Layer 3 Ethernet interfaces GigabitEthernet 2/1/3 and GigabitEthernet 2/1/4 to

aggregation group 2.
