I have a question about exporting policies from a Multi-Site External Network in NDFC 3.2.2m. I have to rebuild the core routers because I already had VPC built when I imported them, and it won't let me add a VPC port channel if the VPC wasn't built ...

I got an inter-fabric link to work between an External and Inter-Fabric Connectivity fabric and a Data Center VXLAN EVPN - iBGP. Now what I need is to create a link between two External and Inter-Fabric Connectivity fabrics, but the the option to cre...

I recall looking at this a while back and letting it go, but it is bothering me again. This is from spec sheet, but it doesn't make sense. There are 6 PCIe slots, MLOM, and MRAID. Where are slots 8, 9, and 10?

This came up in another thread, but I wrote an article on CLN describing how I deployed multi-cluster CER for two different customers. https://learningnetwork.cisco.com/s/article/cer-multi-cluster-design

I have only done NDFC upgrades in a lab with a single VM so far. I have heard more than a few scary stories about this, but I am going to have to figure it out because I have a couple customers running NDFC 3 that need to be upgraded.

I haven't had to do this in quite a while, but I seem to recall the implementationID matched a CUCM CDR item so it could be matched from there.

I have gotten past the initial problem of last year. Now I have a slightly different question. Links work great if NDFC detects them, or even if I build them for point to point connections. Where I don't have an answer is how I can build links when I...

I have experienced similar issues. My best practice for using a VIC is make it a trunk and never utilize the untagged vlan. You can always restrict the allow vlan's. A Nexus switch will silently mask this, so I got surprised when I moved my 40G ports...

Agreed, I have seen that error in that situation more than a few times. It is rather disconcerting, but I prefer to give the VM the additional resources prior to the upgrade as opposed to having something go wrong in the upgrade process for lack of r...
