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...

Hello, I am just trying to understand how ARP in the overlay is handled by SDA. I get all the operation an order of operations. But I have a doubt:When the endpoint sends the ARP request and the Edge Node intercepts it, and then the Edge Node sends t...

Good Day Outliers!I am doing a little lab here, after reading the Discontigous section in the CCNP/CCIE book for ENCOR (Official Cert Guide). The book states:Fair enough. But then it says:The book then states the 3 essential rules:So I was curious if...

Hello!I have a simple LAB:As part of understanding how CEF works, I wanted to see how the FIB and Adjacency Table deal with GRE tunnels. In this case, a simple P2P tunnel using GRE and a FVRF:R1:R2Traffic flows, all good. When I check the FIB on R1 f...

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...

Hello. I suggest you take a look at Troubleshoot ARP Resolution in SD-Access Fabric - Cisco to understand the concept of L2 AR Table and how the first Map Request sent by the EN is actually "give me the MAC-address" because is an Address-Resolution R...

That helped a lot, thank you! You are right, now that I think about it, if the CP resolved ARP completely, then both the sender and receiver will have to query the CP for getting the MAC address... but both the sender EN and the receiver EN still hav...

In my organization we have the same issue. We deploy Configuration Groups to WAN Edge routers running IOS-XE 17.12.6, and vManage running 20.18.x, and every day we get this error on a couple devices. We deploy devices every day, and this error has ha...
