Quick Answer: What is a disadvantage of using eigrp automatic summarization?

What is a disadvantage of using Eigrp automatic summarization group of answer choices?

What is a disadvantage of using EIGRP automatic summarization? It creates inconsistent routing when the network has discontiguous networks. When an organization has discontiguous networks, automatic summarization can cause inconsistent routing.

Why do we use no auto summary in Eigrp?

EIGRP is not going to automatically create the most optimal summary routes for you… EIGRP will check if you have any subnets that fall within the range of your network command (s) and if so, it will advertise the classful A, B or C network to its neighbors.

In which scenario will the use of Eigrp automatic summarization cause inconsistent routing in a network?

In which scenario will the use of EIGRP automatic summarization cause inconsistent routing in a network? If there are discontiguous IPv4 networks, automatic summarization causes inconsistent routing because routes are summarized at classful boundaries.

What are the benefits of summarizing routes?

The advantages of summarization are that it reduces the number of entries in the route table, which reduces load on the router and network overhead, and hides instability in the system behind the summary, which remains valid even if summarized networks are unavailable. The word contiguous sometimes confuses people.

Which operation feature is different between Eigrp and Rip?

Which operation feature is different between EIGRP and RIP? EIGRP stores all routes learned from neighbors in a topology table. The EIGRP protocol only sends routing updates during a topology change or during the initial neighbor adjacency and the updates are in the form of a multicast or unicast.

Which command you will use to prevent auto summary?

Use the command no auto – summary to disable automatic summarization.

What is Eigrp Auto summary?

Auto summarization is a feature which allows Enhanced Interior Gateway Routing Protocol ( EIGRP ) to summarize its routes to their classful networks automatically. For example, consider we are planning to use eight subnets of class B default network 172.16.

How do I turn off automatic summarization?

If you are using RIP Version 2, you can turn off automatic summarization by specifying no auto – summary. Disable automatic summarization if you must perform routing between disconnected subnets. When automatic summarization is off, subnets are advertised.

Why would you turn off automatic summarization for RIPv2?

Due to RIPs classless behavior routing between these networks can be performed without any problems. To be able to do so, you have to disable RIPv2 default behavior of auto summarization so that the appropriate subnet masks can be propagated and update the routing table in each of the routers.

What data is used by OSPF and ISIS for loop prevention?

1 Routing Protocol Overview Link-state protocols like OSPF and ISIS use more CPU and memory resources than distance vector protocols do because they maintain a complete synchronized map of the network and run the SPF algorithm to determine the best path.

What are two reasons for creating an OSPF network with multiple areas choose two?

1. What are two reasons for creating an OSPF network with multiple areas? ( Choose two.) to reduce SPF calculations* to reduce use of memory and processor resources* the use of multiple areas * Type 3 LSAs are generated without requiring a full SPF calculation.​* Type 3 LSAs are used to update routes between OSPF areas.*

What are two reasons that will prevent two routers from forming an OSPFv2 adjacency?

What are two reasons that will prevent two routers from forming an OSPFv2 adjacency? ( Choose two.) a mismatched Cisco IOS version that is used. mismatched OSPF Hello or Dead timers. mismatched subnet masks on the link interfaces. use of private IP addresses on the link interfaces.

How do you summarize a route?

To calculate the summary route, follow these steps: Convert the addresses to binary format and align them in a list. Locate the bit where the common pattern of digits ends. (It might be helpful to draw a vertical line marking the last matching bit in the common pattern.) Count the number of common bits.

What are the benefits of summarizing a text?

Summarizing teaches students how to discern the most important ideas in a text, how to ignore irrelevant information, and how to integrate the central ideas in a meaningful way. Teaching students to summarize improves their memory for what is read. Summarization strategies can be used in almost every content area.

What is the benefit to having a hierarchical design with OSPF?

OSPF is created in a hierarchical design, not a flat design like RIP. This decreases routing overhead, speeds up convergence, and confines network instability to a single area of the network.
