services / Azure / Route table

A route table holds user-defined routes that override Azure's default system routes for the subnets it is associated with, controlling the next hop that traffic destined for given address prefixes takes.

A route table is a perimeter/segmentation control; it determines the path (and therefore the exposure) of a subnet's traffic. Rated consistent with the other network-segmentation resources documented alongside it, rather than CRITICAL, which is reserved for tenant-wide IAM/policy objects.

Deleting a route table removes its user-defined routes from every associated subnet, reverting traffic to default system routing (which can bypass an intended network virtual appliance/firewall hop) or breaking connectivity that depended on a custom route.
