This is very confusing to me. I am working on a large Meraki deployment where the ISP is handing out IPv4 and IPv6 addresses to the WAN interface. Meraki doesn't allow you to disable IPv6 on WAN - Annoying, but fair enough.VLAN SVIs on the LAN termin...
I have been working on an environment where a design was completed prior to my engagement. This is my first foray into configuring VXLAN but I have some experience with overlays/ACI/etc so am fairly comfortable. Design has 2x border leafs, 2x spines,...
Over the last few weeks I've had nothing but issues with the always-on lab. I am guessing it is getting attacked/broken by bad-actors or it is buggy. Using the ACI 5.2 reservation-only lab has been a good workaround but this lab has been decomissione...
I'll try keep this simple using pictures... We want to get from this:

The customer has a quite diverse third-party and platform ecosystem with separate SASE application controls on workstations with their own security controls, 802.1x on LAN as well. They don't use IPv6 internally which is what the MX/SDWAN is providin...
Ok. I may have a smoking gun. It looks like the workstations have a 4G local NIC on them and Meraki might simply be gleaning IPv6 information indirectly about client state (i.e. a IPv6 ND).I was under impression WAN IP was same IPv6 subnet as the pha...
We don't want to use IPv6... which is why SVIs have it disabled. Regardless, clients have IPv6 addresses showing up. The IPs are in the same IPv6 subnet as the WAN carriage so I assume it's SLAAC from the ISP pool. I've read annecdotal advice suggest...
It's been months since I raised this but since there was some traffic on this post I wanted to share some information. The answer provided by Pavel is correct.
Some pointers to keep others out of trouble...

As someone who had similar issues in April/May 2023 when testing/developing Python scripts on the always on lab. My advice for those that follow is to check the Webportal via a standard web-browser. If you have issues with that, a python request isn'...
