LTM in Azure - VIP not responding

I have 2 machines in the Azure cloud, both on the same subnet / vnet 10.1.1.0/24

 

I can ping the Self IP of the LTM 10.1.1.100 but not the VIP 10.1.1.200 - if we were in the "real world" then the LTM isn't ARPing for the .200 address but as this is cloud and there's no L2 I'm wondering how I get this to work ..

 

Any tips anyone?

 

Tnx

If you created 10.1.1.200 on your ltm then the cloud provider is not aware of it and as you said arp is not an option. You need to create the VIP with 10.1.1.100 or 0.0.0.0, then you have options to distinguish between different apps, e.g using a specific port on each VS or using a traffic policy which checks the hostname and acts accordingly
