In other words, it is the believability of the source of the route. Sep 27, 2024 · This document describes the administrative distance feature that routers use to select the best path when there are two or more different routes. In Junos OS, static routes have a global preference (administrative distance) of 5. Then administrative distance is considered. Local preference is sent to all internal BGP routers in the autonomous system, and the path with the highest local preference is preferred. Like LikedUnlike Reply Samer Edited by Admin February 16, 2020 at 4:47 AM Hi BGP local preference is what we can use when we want to prefer one exit over another within on AS, normally this is applied on border bgp routers on the external point of contact, and its applied inbound for example: Jan 25, 2022 · Excuse a router in its routing table gives priority to prefix length or administrative distance? For example, if I have a route eigrp / 24 and a route ospf / 28 which router will insert in the routing table? They taught me the most specific route before anything else but I see conflicting opinions o Jul 30, 2021 · Prefer Highest Local Preference: This attribute is used within the same AS to determine the preferred path for outbound traffic. Network scenario used for this example : [ FortiGate ][ PC ] -- LAN -- Jun 16, 2024 · Administrative distance China has a complex and bureaucratic regulatory environment, with different rules and regulations at the national, regional, and local levels. Case study: Assume that a default route is learned via BGP, and another default route is configured as static route. In this lesson, you learn the BGP attributes and how BGP selects the best path. Select OMP route with lower administrative distance. Administrative Distance (AD) is a value from 0 to 255 used by routers, primarily Cisco devices, to determine the trustworthiness of a routing information source. When a router learns multiple paths to the same destination from different routing protocols, it uses the AD to select the best path. Routing information can be learned from multiple sources. FortiGate allows setting local preference values, which apply only to paths within the AS. If multiple routes exist and all three of these attributes are identical, the Router will load balance across the available paths. Or it should. 0. I know it modifies admin distance specifically, which makes sense if you're learning the same route from multiple protocols. Dec 15, 2010 · My confusion is: should R2 always use a ebgp route because lower administrative distance? but in that case, what about the local preference path selection? (this example is very typical in CCNP and CCIE books. I want to know if i understand this correctly or if i am missing something. I probably could have shortened it up to ask if modifying the admin distance of one of the default route from ISP A had the same effect as modifying local preference with an import policy. By increasing the administrative distance of a static route to a value higher than a dynamic route, you can use the static route as a backup route if the dynamic route is unavailable.

Administrative distance is a numerical value assigned to different routing protocols or static routes, representing their trustworthiness or preference. This value makes them preferred over routes learned from dynamic protocols like OSPF or BGP. A dministrative D istance or Priority is a networking operating system specific priority table for the supported routing protocols. Then inside OSPF, the process is more complex. Select the OMP route with the higher OMP preference value. Same administrative distance, but different priorities = both routes get installed, but the lower priority one is preferred. Cisco's IOS calls it Administrative Distance, other vendors call it Default Preference, Distance, many vendors call it Priority. For both administrative distance and route preference, a lower value is preferred. Routes that are learned through explicit administrative action, such as static routes, are preferred over routes learned from a Mar 20, 2025 · The administrative distance of 110 would trump the artificially high administrative distance of our floating static route, and the RIB would go back to oh, well, my better route is now my OSPF learned route and the dial interface would would go away. Cisco Administrative distance – This is the measure of trustworthiness of the source of the route. Reductions in Force May 8, 2017 · Administrative distance the word you always hearing whenever you heard about the routing Protocols and you are very much aware of the AD values of all the routing protocols. This example shows how to use routing policy to set the preference for routes learned from BGP.
