agree, i think the answer should be 'delete peering1'. according to: https://docs.microsoft.com/en-us/azure/virtual-network/virtual-networks-faq#vnet-peering : If your VNet peering connection is in a Disconnected state, it means one of the links created was deleted. In order to re-establish a peering connection, you will need to delete the link and recreate it.

I would say that "delete peering1" would seem to be correct; however, the documentation here says you have to delete the peerings from BOTH vnets: https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-troubleshoot-peering-issues If the "delete peering1" answer is then wrong in favor of deleting both peerings which isn't a choice, then you have to float to the next most logical alternative, which might be adding address space. Not sure on this one.

Why modifying the address space? We don't even know which address space are used here, hence maybe is no overlapping at all.

why vnet6 only?

Because peering status is "Disconnected" hence host on Vnet 6 can connect to Vnet 6 hosts only.

Steps are 1) delete peering 2) add Address Space 3) Add subnet 4) Create new peering So first is to delete the existing peering

You can't add address ranges to or delete address ranges from a virtual network's address space once a virtual network is peered with another virtual network. https://go.microsoft.com/fwlink/?linkid=2113320 So to modify the address space , the peering should be deleted first

As troubleshooting, i would say that first thing to verify is address space overlapping.

If you needed to do this. There would not have been an initial connection. So we just need to create the Peering again

For sure the peering must first be deleted (in case we have an address space overlap that is): "You can't add address ranges to, or delete address ranges from a virtual network's address space once a virtual network is peered with another virtual network. To add or remove address ranges, delete the peering, add or remove the address ranges, then re-create the peering. "

Question is incomplete to answer justify the answer "modify the address space". I agree with the other comments, "delete peering1" should be the answer.

Scenario - 1 --> Address space if overlapping (Box 2 - It should be Delete Peering first.) 1. Delete Peering 2. Update Address space if overlapping 3. Create Peering. Scenario - 2 The peering status is "Disconnected" (Box 2 - It should be Delete Peering first.) To resolve this issue, delete the peering from both virtual networks, and then re-create them. https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-troubleshoot-peering-issues

Either the question is incomplete or answer is wrong. We don't see any IP address ranges so how can we know if there is any address overlapping. I think the best answer is to delete the peering.

From: https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-troubleshoot-peering-issues The peering status is "Disconnected" => To resolve this issue, delete the peering from both virtual networks, and then re-create them.

in the available options only delete peering1 available. If we delete peering 1 it will not resolve overall problem so i think the correct option is modify the address space from the available options.
