Since I am new to SDAccess fabric world just putting up a weird question. Is there by any means we can run a SDA fabric in a layer 2 setup (by configuring the different IP pool subnet's gateway in a L3 switch or firewall outside the fabric).
Cisco DNA Center Version 2.3.3.7-72328 We have a use case where we'd like to swap a C9500-24Y4C for a C9500-48Y4C. Is this possible in DNAC, or would the new 48 port switch need to be added to the inventory/fabric site, assigned the fabric role[s] be...

Resolved! Redistribution from BGP to LISP
Hi,In SDA, what is the reason of redistributing BGP routes to LISP at border/control node?I mean, with Proxy-xTR, every edge node will forward packet to it if it receives negative map reply from MS/MR. Then, Proxy-xTR will perform another check with ...
