We have had a VPN tunnel setup to our VNET some time now from our Cisco ASA to Azure. I route a /16 say 10.200.0.0/16 to this VNET. The Sys Eng managing our Azure accounts/VNETs has added a new VNET and assigned it to say 10.200.32/0/20. In order to reach the new VNET via the existing tunnel and VNET, what does he need to add to Azure?
