Software Defined Access Fabric Guest wired / wireless in Cisco DNA Center 

Hi, Yes /31 is allowed in that field. Hope that helps.

@@pabmart yep, thanks

In this series, I used the Dedicated Guest VN. It uses the same B/CP as the other VNs. By ticking the box for Guest VN, Catalyst Center recognizes it. When you want to add a Guest SSID or a captive portal, Catalyst Center will know it is for guests and give you the subnet from the Guest VN pool when enabling it. So, it makes it easier.

Hi, no IGP between them in this lab. I'm using static routes, and then BGP for the L3 handoff. Hope that helps.
