What is the AD assigned to ODR routes?

The Administrative Distance (AD) assigned to On-Demand Routing (ODR) routes is 160. This value indicates the trustworthiness of routes learned via ODR compared to other routing protocols.

ODR is a routing protocol that allows routers to share route information without the overhead of traditional routing protocols, making it more efficient in some scenarios, particularly in environments with Cisco devices. An AD of 160 means that ODR routes are less reliable than those learned through protocols like EIGRP (which has an AD of 90) or OSPF (which has an AD of 110), but more reliable than static routes (which typically have an AD of 1). This hierarchy of distance values enables routers to evaluate which routes to trust when multiple sources provide routing information.

The other options, such as 170, 200, and 255, are assigned to different routing protocols or signify various meanings in routing contexts. For example, an AD of 255 indicates that routes are unreachable, while 200 is not commonly used for standard routing protocols. Understanding the significance of ODR's AD is crucial in managing routing effectively in a network.
