Azure Network Watcher next hop
Traffic from a virtual machine (VM) is sent to a destination based on the effective routes associated with the virtual machines' network interface (NIC). Azure Network Watcher next hop gives you the Next hop type, IP address, and Route table ID of a specific destination IP address. Knowing the next hop helps you determine if traffic is being directed to the intended destination, or whether the traffic is being sent nowhere. An improper configuration of routes, where traffic is directed to an on-premises location, or a network virtual appliance, can lead to connectivity issues. If the route is defined using a user-defined route, the route table that has the route is returned. Otherwise, next hop returns System Route as the route table.
