### Issue Details
Read me provides URL to an an arm template for creating back end pool for LB using Network interface is broken. I am trying to find an example that will show me how to achieve a backend pool using NIC vs ip address.

Start with the linked 101-load-balancer-ip-configured-backend-pool template and its README URL. Verify why the documented ARM template link is broken, then compare the example with the requested NIC-based backend pool configuration. Done means the reference works and the example clearly covers backend pools using NICs rather than only IP addresses.
