2.8.3 Example for Configuring Layer 3 Link Aggregation
Networking Requirements
RouterA and RouterB are connected by two Layer 3 Ethernet interfaces. To increase link
bandwidth and improve reliability, you can create an Eth-Trunk on each router and add the Layer
3 Ethernet interfaces to the Eth-Trunk.

Configuration Roadmap
The configuration roadmap is as follows:
1. Create a Layer 3 Eth-Trunk on each device and configure an IP address for each Eth-Trunk.
2. Add Ethernet interfaces to the Eth-Trunk.
Procedure
Step 1 Configure RouterA.
<Huawei> system-view
[Huawei] sysname RouterA
# Create a Layer 3 Eth-Trunk (Eth-Trunk 1) and configure an IP address for Eth-Trunk 1.
[RouterA] interface eth-trunk 1
[RouterA-Eth-Trunk1] undo portswitch
[RouterA-Eth-Trunk1] ip address 10.1.1.1 24
[RouterA-Eth-Trunk1] quit
# Add Ethernet1/0/0 and Ethernet2/0/0 to Eth-Trunk 1.
[RouterA] interface ethernet 1/0/0
[RouterA-Ethernet1/0/0] eth-trunk 1
[RouterA-Ethernet1/0/0] quit
[RouterA] interface ethernet 2/0/0
[RouterA-Ethernet2/0/0] eth-trunk 1
[RouterA-Ethernet2/0/0] quit
Step 2 Configure RouterB.
<Huawei> system-view
[Huawei] sysname RouterB
# Create a Layer 3 Eth-Trunk (Eth-Trunk 1) and configure an IP address for Eth-Trunk 1.
