Layer 3 static aggregation configuration example

On the network shown in Figure 16, perform the following tasks:

• Configure a Layer 3 static aggregation group on both Device A and Device B.

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

1. Configure Device A:

   # Create Layer 3 aggregate interface Route-Aggregation 1, and configure an IP address and subnet mask for the aggregate interface.

   <DeviceA> system-view
   [DeviceA] interface route-aggregation 1
   [DeviceA-Route-Aggregation1] ip address 192.168.1.1 24
   [DeviceA-Route-Aggregation1] quit
   

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

   [DeviceA] interface ten-gigabitethernet 1/0/1
   [DeviceA-Ten-GigabitEthernet1/0/1] port link-aggregation group 1
   [DeviceA-Ten-GigabitEthernet1/0/1] quit
   [DeviceA] interface ten-gigabitethernet 1/0/2
   [DeviceA-Ten-GigabitEthernet1/0/2] port link-aggregation group 1
   [DeviceA-Ten-GigabitEthernet1/0/2] quit
   [DeviceA] interface ten-gigabitethernet 1/0/3
   [DeviceA-Ten-GigabitEthernet1/0/3] port link-aggregation group 1
   [DeviceA-Ten-GigabitEthernet1/0/3] quit
   

2. Configure Device B in the same way Device A is configured. (Details not shown.)

# Display detailed information about all aggregation groups on Device A.

[DeviceA] display link-aggregation verbose
Loadsharing Type: Shar -- Loadsharing, NonS -- Non-Loadsharing
Port Status: S -- Selected, U -- Unselected
             I -- Individual, * -- Management port
Flags:  A -- LACP_Activity, B -- LACP_Timeout, C -- Aggregation,
        D -- Synchronization, E -- Collecting, F -- Distributing,
        G -- Defaulted, H -- Expired

Aggregate Interface: Route-Aggregation1
Aggregation Mode: Static
Loadsharing Type: Shar
Management VLAN : None
  Port               Status  Priority Oper-Key
--------------------------------------------------------------------------------
  XGE1/0/1           S       32768    1
  XGE1/0/2           S       32768    1
  XGE1/0/3           S       32768    1

The output shows that link aggregation group 1 is a non-load-shared Layer 3 static aggregation group that contains three Selected ports.
