Configuring a Layer 3 Link Aggregration Group (LAG)

Configuring a Layer 3 Link Aggregration Group (LAG).

FastIron devices with Layer 3 images support Layer 3 LAGs, which are used for routing and not switching. Perform the following steps to enable routing on a LAG:
  1. In the global configuration mode, run the interface lag command to enter the LAG virtual interface configuration mode.
    device(config)# interface lag 55
  2. Run the route-only command to disable switching and enable routing on the LAG.
    device(config-lag-if-lg55)# route-only
  3. Run the ip address command to assign an IP address for the LAG.
    device(config-lag-if-lg55)# ip address 25.0.0.2/24

The following example shows the creation of a dynamic LAG that is used for routing on a FastIron device with Layer 3 image.


device(config)# lag “ruckus-LAG” dynamic id 55
device(config-lag- ruckus-LAG)# ports ethernet 4/1/4 ethernet 1/1/1 ethernet 2/1/3 ethernet 3/1/4             
device(config-lag- ruckus-LAG)# exit
device(config)# interface lag 55           
device(config-lag-if-lg55)# route-only
device(config-lag-if-lg55)# ip address 25.0.0.2/24
