LAN automation for new fabric edge to dual-homed non-SVL border

[darrenpjw]

Hi,

I have 2 border nodes running as L3 between them in a SDA design. I would like to perform LAN automation for new fabric edges and they have dual-homed link to both borders. How do perform LAN automation to select both borders?

You would select one border as primary seed device and one as secondary seed device. From there you onboard it as you usually would. Good luck!

Hi!

Thanks for the feedback. But how can I select the interface on the secondary seed device? I can only see the option to select interface for primary seed device? How would the fabric edge node knows which interface on the secondary border to establish underlay?

Hi, it's derived from CDP, from the LAN Automation Deployment Guide, "The option to choose a peer seed interface is not available. Interfaces between peer seed and PnP agents are automatically inferred based on the topology information gathered from the device. The topology information is built on the CDP information available on the device. "
