What is the administrative distance of OSPF?
What is the administrative distance of OSPF?
110
The range for administrative distance is 0–255. The default value is 120 for RIP routes and 110 for OSPF routes.
How do you route summarize in OSPF?
To summarize routes sent to the backbone area:
- Configure the interfaces.
- Configure the type of OSPF area.
- Assign the interfaces to the OSPF areas.
- Summarize the routes that are flooded into the backbone.
- On ABR R3, restrict the external static route from leaving area 0.0.
Does OSPF support route summarization?
Route summarization helps reduce OSPF traffic and route computation. OSPF, unlike EIGRP, doesn’t support automatic summarization. Also, unlike EIGRP, where you can summarize routes on every router in an EIGRP network, OSFP can summarize routes only on ABRs and ASBRs.
What is OSPF summary address?
This topic describes how to configure route summarization in OSPF….Configuring OSPF Route Summarization.
| Parameter | Description |
|---|---|
| area-id | Identifies the area subject to route summarization. |
| address | Summary address that is designated for a range of addresses. |
| mask | IP subnet mask that is used for the summary route. |
How do you find administrative distance?
You can display the administrative distance of all routes on your router by typing the show ip route command:
- In the case above, the router has only a single route in its routing table learned from a dynamic routing protocols – the EIGRP route.
- Metric.
- RIP has been configured on all routers.
What is the administrative distance of OSPF Mcq?
Solution(By Examveda Team) The administrative distance (AD) is a very important parameter in a routing protocol. The lower the AD, the more trusted the route. If you have IGRP and OSPF running, by default IGRP routes would be placed in the routing table because IGRP has a lower AD of 100. OSPF has an AD of 110.
What is Summarised route?
Route summarization — also known as route aggregation — is a method to minimize the number of routing tables in an IP network. It consolidates selected multiple routes into a single route advertisement. This differentiates it from flat routing, in which every routing table carries a unique entry for each route.
What is administrative distance in router?
Administrative distance (AD) or route preference is a number of arbitrary unit assigned to dynamic routes, static routes and directly-connected routes. The value is used in routers to rank routes from most preferred (low AD value) to least preferred (high AD value).
What is the administrative distance of default routes?
THe max admin distance for any static route (including default) is 255. Default is the least preferred route as long as there is a better IP match in the routing table.
What does administrative distance mean?
Administrative Distance (AD) is a value that routers use in order to select the best path when there are two or more different routes to the same destination from two different routing protocols. Administrative Distance counts the reliability of a routing protocol.
What is the default hop count of OSPF?
OSPF protocol has no limitations in hop count, unlike RIP protocol that has only 15 hops at most.
