Hello Team,
We are having a very simple scale question concerning the amount of L2 Handoff borders in a site. In the design guides we only see examples with one L2 Handoff Border in a site, which you can see in https://www.cisco.com/c/en/us/td/docs/solutions/CVD/Campus/cisco-sda-design-guide.html#L2_Border_Handoff.
We are not seeing any scale numbers for the amount of L2 Handoff Borders (L2Border) in a site.
We need a second L2 Handoff border in a site to stretch some subnets from a second L3 distribution point in the building of his traditional environment. They are using the same VLAN ID’s, and of course different subnets, so adding a second L2 Handoff border is necessary to stretch them to the fabric site.
We tested it in our LAB by adding a second L2 Handoff border to a single-site and it worked like a charm. This test site consist of two External borders, and by adding the two L2 Handoff borders the total amount of borders in the site was four.
Our question: How many L2 Handoff Borders can we add to a single-site? The official border type is “L2Border” instead of “Internal” or “External” so it looks like it doesn’t count as border in the site.
Thanks in advance for your answer.
Solved! Go to Solution.

@Jasper van Nederpelt , L2 Borders have he same scale as the "Internal" border type, which is to say there really is no limit except for the limit on the number of fabric devices in a site (see DNA Center Data Sheet https://www.cisco.com/c/en/us/products/collateral/cloud-systems-management/dna-center/nb-06-dna-center-data-sheet-cte-en.html Table 14).
