Here is the scenario:
TESTSite-A <------> OnPrem (ExpressRoute established)
TESTSite-A <------> SITE B (VNET TO VNET Required)
TESTSite-A <------> SITE C (VNET TO VNET Required)
SITE B <--------> SITE C (VNET TO VNET Required)
SITE C <------> SITE B (VNET TO VNET Required)
Updated the XML VNETConfig for the TESTSITE-A with the additional gateways file ready to import when I receive error:
The gateway in virtual network site TESTSITE-A referenced multiple local network sites and uses a connection type different than 'IPsec' for at least one of the connections. If a gateway references more than one local network site, the connection type to all local network sites must be 'IPsec'. 'IPsec' is the default connection type.
Obviously my ExpressRoute connection is a 'Dedicated' connection type and the other two gateways are IPSEC (VNET TO VNET). Surely what I want to do is possible? Does anyone know how I can get intersite connectivity between the other VNETS AND TESTSITE-A? Without breaking my ExpressRoute connection?
