2003-05-19 · For example, if a router receives a route to a certain network from both Open Shortest Path First (OSPF) (default administrative distance - 110) and Interior Gateway Routing Protocol (IGRP) (default administrative distance - 100), the router will choose IGRP because it is more reliable.

Reply. 14 Apr 2010 For example, in OSPF there are different types of routes: intra-area, Cisco documentation describes "administrative distance" as "This is the  21 Sep 2011 Changing AD in OSPF.

I configured OSPF and IS-IS on Arista vEOS 4.25.0FX-LDP-RSVP (with OSPF taking the role of EIGRP in the above example). These are the entries from the main IP routing table: Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS). 2011-07-10 · Administrative Distance (AD) values in Cisco & Juniper AD value is a reliability or trustworthiness of a protocol, for selecting routes to be placed in routing table. If a router has routes to same destination from two different protocols it will prefer the protocol with lowest AD value, and its routes will be installed in the Routing / Forwarding table. Lower administrative distances are preferred over higher distances. For example, if the device receives routes for the same network from OSPF and from RIP, the device will prefer the OSPF route by default.

The administrative distance can be modified. For example, if a router receives a route to a certain network from both Open Shortest Path First (OSPF) (default administrative distance - 110) and Interior Gateway Routing Protocol (IGRP) (default administrative distance - 100), the router will choose IGRP because it is more reliable. In today’s post, we will discuss another OSPF filtering technique: Filtering with Administrative Distance. Before start digging into how to apply this type of filtering let’s recall how Cisco routers pick the best path: Prefix length: Routers always use this method first; it compares the destination network with the available prefixes in the routing table… The router will usually compare administrative distances to determine which protocol has the lowest value.

Administrative distance for ospf

The route from R4 will be in OSPF (admin distance of 110) because R2 is also running OSPF while the route from R3 will be an external EIGRP route (administrative distance of 170 by default). Since the OSPF route has a lower administrative distance, it will get placed in …

Administrative distance for ospf

The best route is the route that will be installed in the IP routing table. This is because EIGRP routes have (by default) the administrative distance of 90, while RIP route have a higher administrative distance of 120. You can display the administrative distance of all routes on your router by typing the show ip route command: Command.

Answer: C Explanation: Default Distance Value Table This table lists the administrative distance default values of the protocols that Cisco supports: A permanent routing loop between R1 and R2 can be created by leaving the administrative distances at their default values on R1 and, on R2, by setting the administrative distance of RIP-discovered routes from R1 to a value lower than 110 to favor them more than OSPF-discovered routes.

Administrative distance for ospf

OSPF has an AD of 110. RIPv1 and RIPv2 both have an AD of 120, and EIGRP is the 2021-4-11 · Administrative distance is one of the main criterion to determine a preferred route when there are multiple paths to the same destination.

Example. In this example, we will change OSPF administrative distance to 150 for internal routes and 220 for external. The only situation where you can avoid this is OSPF, where filtering on "advertising router" is actually useful because it refers to the other border router, not the upstream neighbor.
