Layer 2 Border connectivity

Hi,

For migration from traditional network to SD-Access, L2 border physically will need to be connected to Fabric Border or Legacy Core switch or both

Thanks

L2 border is border that has to be contended to fabric with one side and to legacy network on other. It can be a separate border to l3 borders. Check scalability limitations regarding it, Mac address table size, and resiliency.

@bofele

Both interfaces on the L2 border can be configured through DNAC?

Fabric is underlay. Automated way is Lan automation. But one can also create minimal manual configuration. With manual configuration one had to be sure that multicast is there, for native support in overlay and for BUM traffic.

Recommend doing L2 hand off with DNAc.
