In this example, an L3 VLAN with static routes is used. An L3 VLAN uses multiple links to the existing network. Each link is assigned as a member in a port channel to the existing network. Interfaces Ethernet 1/1/55:1 and 1/1/56:1 on both leaf switches connect to the external switches.
The following figure shows the example topology.
To configure an uplink using an L3 static route, perform the following steps.
L3 uplink verification
Confirm the active status of the uplinks by running the show vlan command.
