Layer 3 edge aggregate interface configuration example

As shown in Figure 18, a Layer 3 dynamic aggregation group is configured on the device. The server is not configured with dynamic link aggregation.

Configure an edge aggregate interface so that both Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 can forward traffic to improve link reliability.

# Create Layer 3 aggregate interface Route-Aggregation 1, and set the link aggregation mode to dynamic.

<Device> system-view
[Device] interface route-aggregation 1
[Device-Route-Aggregation1] link-aggregation mode dynamic

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

[Device-Route-Aggregation1] ip address 192.168.1.1 24

# Configure Layer 3 aggregate interface Route-Aggregation 1 as an edge aggregate interface.

[Device-Route-Aggregation1] lacp edge-port
[Device-Route-Aggregation1] quit

# Assign Layer 3 Ethernet interfaces Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 to aggregation group 1.

[Device] interface ten-gigabitethernet 1/0/1
[Device-Ten-GigabitEthernet1/0/1] port link-aggregation group 1
[Device-Ten-GigabitEthernet1/0/1] quit
[Device] interface ten-gigabitethernet 1/0/2
[Device-Ten-GigabitEthernet1/0/2] port link-aggregation group 1
[Device-Ten-GigabitEthernet1/0/2] quit

# Display detailed information about all aggregation groups on the device when the server is not configured with dynamic link aggregation.

The output shows that Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 are in Individual state when they do not receive LACPDUs from the server. Both Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 can forward traffic. When one port fails, its traffic is automatically switched to the other port.
