DNAC Anchor VN Removal Process?

dwright6123 — Tue, 12 Apr 2022 18:41:09 GMT

I seem to have worked myself into a corner on this one waiting for TAC support contract to come thru. Essentially, I built out a fabric site in DNAC and added a C9300 switch to said fabric, in doing so I added several VN's as "Use Border/CP fort his site to be common for the Virtual Network" (not exactly knowing what that meant because documentation is not very clear on this). Anyways, after doing this I realized that all of this was setup on the site level instead of the configured Fabric Zone level of the hierarchy. Now it seems I cannot remove the VN's to start over, I can go in and uncheck the check box and hit deploy and I get a success message however, the VN still shows anchored with no underlying configurations? At this point I tried to remove the switch from the Fabric and it fails saying it can't be removed with L3 Handoff configured (assuming VN related), I tried deleting the fabric and it says can't delete because devices are assigned. I guess the problem is I just want to start over and I cannot for the life of me figure out how to do this? Any help would be appreciated.

""Use Border/CP fort his site to be common for the Virtual Network" this should be used if you intend to send traffic from the VN to outside the Fabric.

Now, not be able to remove the VN is actually weird.

Yes, that was exactly the reasoning for checking the box 😊 Anyways, finally have my contract# for TAC support so I’m going to kick it their way.

Update, this ended up being DNAC bug of some sort, TAC had to API in and manually delete some things, then everything magically started working again.
