What is the administrative distance for a directly connected route?
An administrative distance is a number between 0 and 255, with the lower number being better. The AD of 0 indicates the most trusted route (the directly connected network). The AD of 255 means that the route will not be trusted.
What is administrative distance and metric?
In other words, the administrative distance is used to compare routes originating from different routing protocols (including static and connected), whereas the metric is used to compare routes within one single source of origin or family.
Is the default administrative distance of RIP?
The default administrative distance of RIP is 120.
Can we change administrative distance?
Keep in mind: The administrative distance is only local and can be different for each router. The administrative distance can be modified.
What is metric rip?
Routing Information Protocol (RIP) Overview. RIP uses a hop count metric to measure the distance to a destination. In the RIP metric, a router advertises directly connected networks at a metric of 1 by default. Networks that are reachable through one other gateway are 2 hops, etc.
What is administrative distance of RIP?
By default, OSPF has a default administrative distance of 110 and RIP has a default administrative distance of 120.
What is default administrative distance for BGP?
20
Administrative distance is the first criterion that a router uses to determine which routing protocol to use if two protocols provide route information for the same destination….Default Distance Value Table.
| Route Source | Default Distance Values |
|---|---|
| External Border Gateway Protocol (BGP) | 20 |
| Internal EIGRP | 90 |
| IGRP | 100 |
| OSPF | 110 |
How to set the administrative distance for a BGP route?
To set the administrative distance for BGP routes, see JunosE BGP and MPLS Configuration Guide. You can set the administrative distance for RIP, IS-IS, and OSPF using the distance and distance ip commands. To set an administrative distance: For RIP and OSPF, issue the distance command in Router Configuration mode.
What should the administrative distance be for Rip routes?
In order to enable the router to prefer RIP routes to IGRP, configure the distance command on R1 like this: Now look at the routing table. The routing table shows that the router prefers the RIP routes. The router learns RIP routes with an administrative distance of 90, although the default is 120.
When to increase the administrative distance of IGRP?
For example, if you want the router to select RIP-learned routes (default value 120) rather than IGRP-learned routes (default value 100) to the same destination, you must increase the administrative distance for IGRP to 120+, or decrease the administrative distance of RIP to a value less than 100.
Which is the default administrative distance for OSPF?
The default administrative distance of OSPF is 110 while that of the eBGP is 20. With the command distance, we changed the AD value of BGP to 190. Prior to this command, the router R2 preferred the BGP routes over OSPF since they had the default AD values configured.
