Hi Folks,

Can anyone here please share what we need to check before peering two VNets together? (eg. Subnets or IP ranges)

Because one of the VNET is peered with the Azure Express Route circuit to our OnPremise data center to allow Azure connectivity to the OnPremise Datacenter, I wonder if there could be a possibility that can bring the whole OnPremise data centre or Azure VNET some issue?

Thanks in advance,

    There is only one important thing to check:
    Make sure you don't have any overlapping IP address ranges on premises or any Azure vNet or Subnet you like to peer.
