Configure Layer 3 VLAN uplink

For L3 VLAN underlay connectivity, create a L3 VLAN uplink and associate a network and routing policy with the uplink. To do so:

1. Launch the Create Uplink for External Network Connectivity wizard.
2. Select the Uplink Connectivity as Layer 3.
3. Select the Network type as L3 VLAN.
4. Create a L3 VLAN uplink by providing the name and description, and click NEXT.
   NOTE L3 uplinks can be created on leaf and spine switches.
5. Associate the interfaces of the spine or leaf switches with the L3 uplink.
   • Spine — Select a spine switch and an interface or multiple interfaces of the spine switch to be associated with the uplink.
   • Leaf — Select a leaf switch from the rack, and an interface or multiple interfaces of the leaf switch to be associated with the uplink.
6. Select the static or dynamic LAG based on the configuration setup in the external network, and click NEXT.
7. Create a L3 VLAN network by providing name, description, and VLAN ID, and associate to the selected interfaces.
8. Select if the network is a tagged or an untagged network.
9. Enter the IP address for the network. You can use the + symbol to add more IP addresses.
10. Define a routing policy to associate with the uplink based on the external network connectivity setup.
    • Static Route — A route policy template that contains a network prefix and the next hop IP address.
    • eBGP — A routing policy template that contains BGP peer IP address and the remote AS number.
