Hello,Why is IS-IS level-1 not used in SDA, instead of level-1-2? Why on an SDA site we need to mantain a level-2 adjacency and database too, if we can just have everything on the same area? In what production scenario do we benefit from level1-2 on ...

Hello, Just a quick doubt. When I hit the Deploy button in the end of the workflow in a Configuration Group in order to deploy a device, the behavior I see is that initally the operation takes longer than future deployments of the same device for sma...

Hello,I am trying to clarify a little doubt. Considering that I am using SDA with LISP Pub/Sub Model, when a client roams (either Wired or Wireless), is the CP going to publish the L2 and L3 Client address+ new RLOC entries to all subscribed nodes (t...

Why not level-1 (all in the same area, where the area can be understood as the site itself). Why having multiple areas if I can just have everything on 1, for the sake of simplicity.

With level-1 only switches only need to maintain 1 database rather than 2. No need to copy level-1 information to level-2 database. Less calculations, less workload, ... and simple setup.

Mmmm... interesting. I will have to lab this once I get my DNAC back up again and see if the CP actually publishes to BN and to ENs about the roaming update, or just to BNs...

@Andrii Oliinyk Is all actually shown in the document I referenced in my previous reply to you... Cisco shows the debugging and how the CP actually replies to the first ARP request with the MAC address of the target host. Look at the LISP Map-Reply f...
