The platform that you are running is ASR9k and not ASR1k. Also, the ports that you are seeing are satellite links. the reason that you are seeing 100/0/0/42 and other interfaces is because of below configuration:
nv satellite 100 type asr9000v description CHCGILTCHU6_100 ! You can refer to the below command guide for reference:
https://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/nV/command/reference/b-nv-cr-asr9k/b-nV-cr-asr9k_chapter_01.html
Hope this answers your question.

Hi
Could you please share the topology along with running config and BGP table information before and after the outage. You can share that in a file or send me a direct message.

You are most likely hitting defect - CSCuv29358
I would recommend you upgrade your code to 7.0(3)I7(3) or I7(4).

What kind of FEX's are you running? This seems to be a cosmetic issue.

Hi
What is said is true for an individual VTEP that there is a 1:1 mapping between the VLAN and the VNI but in a VXLAN fabric, you can have different VTEPS with different VLANs be mapped to a same VNI. For instance, VLAN 100 on VTEP-1 can be mapped to VNI 10000 and VLAN 200 on VTEP-2 may be mapped to the same VNI 10000. thats how you can scale within the fabric.
Also, there might be future enhancements that might allow more VNI's on a single VTEP.

i would suggest first create another VDC, assign resources / interfaces to it and enter into that VDC and then try enabling the features.
Please share the output of show vdc and show vdc membership. this might help me get a better understanding on what is happening on the system.

I see that you have the Transport Service license which is required for OTV. Could you please share the output of show vdc.
I think you are in admin VDC and thus unable to see the option to enable feature OTV. switch to the relevant VDC and then try enabling feature otv in that VDC.
Hope this helps.

Hi
Sorry for the late response. Been busy with Cisco Live and other work, so couldnt reply you early.
As mentioned before, you can only have 1 L3 VNI per tenant and multiple L2 VNI's. If you are having a multi-tenancy environment, then you need to create separate L3 VNI's for each Tenant.
Please let me know if you have any other questions or if that answers your question.

The spines are there to provide connectivity between the leaf switches. OSPF/ISIS is a better option as Underlay IGP or you can also use EBGP as your underlay.
Yes, all the VNI related configs and NVE (overlay) interface on Leaf switches.

The Spine does not contain VNI's. It is usually configured as BGP RR or RP for Multicast core.

To fix this, you need to use the scp image compacting feature, the local image compacting is not supported.:
https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus3000/sw/release/70372/n3k_70372_nxos_rn.html#_Toc498583962
Please do it “on the fly”, when downloading the image to the switch from its CLI via SCP, the compact option with copy command is allowed only with SCP protocol, the command is: switch# copy scp:<source image name> bootflash:<image name> compact vrf <vrf name>
Note: if you already have the image on the bootflash, you’ll have to delete it first for the above command to work.
Hope this helps
