7.7 EIGRP for IPv4 Configuration

Question 1

What is the first step in configuring a router using EIGRP

Answer 1

Go into EIGRP mode and define an autonomous system number (AS)

Question 2

Describe Equal load balancing

Answer 2

routes whose metrics are relatively close in value can be configured to be equal

Question 3

Describe Auto-summarization

Answer 3

a feature which allows Routing Information Protocol (RIP) to summarize its routes to their classful networks automatically.

Question 4

Describe contiguous

Answer 4

A classful network in which packets sent between subnets pass only through subnets of that same classful network without having to pass through subnets of any other classful network. In other words, the networks are side by side.

Question 5

Describe Discontiguous

Answer 5

A discontiguous network is a classful network in which packets sent between subnets must pass through one or more subnets of a different classful network. The address space for the subnet sending the packets and the subnet(s) the packets pass through are different.

Question 6

What command disables auto-summary

Answer 6

no auto-summary command.

Question 7

Router#show ip route

Answer 7

Displays EIGRP learned routes.

Question 8

Router#show ip eigrp neighbors

Answer 8

Displays neighboring routers from which EIGRP routes can be learned. Lists the IP address of the connected router.

Question 9

Router#show ip eigrp interfaces

Answer 9

Displays the interfaces that are running EIGRP and the number of connected routers.

Question 10

Router(config)#router eigrp [number]

Answer 10

Defines an EIGRP process. The number must match between routers for information to be shared.

Question 11

Router(config‑router)#network [n.n.n.n]

Answer 11

dentifies a network that participates in the routing process. Networks can be specified with or without the wildcard mask. If you do not use a wildcard mask, the network address you add is automatically truncated based on classful network boundaries. You must use a wildcard mask to identify VLSM subnets.

Question 12

Router(config‑router)#no auto-summary

Answer 12

Turns off automatic route summarization. With automatic route summarization, subnets are summarized based on classful boundaries when advertising routes on networks with a different class boundary. You must disable automatic summarization if you have a network address (such as 10.0.0.0) subnetted into smaller subnets and separated by a network with a different classful network address (such as 12.0.0.0).

Question 13

Router(config‑router)#maximum-paths

Answer 13

Uses the maximum-paths subcommand to control the maximum number of parallel routes that EIGRP will support. To remove a maximum-paths subcommand and restore the default, use the no form of this command.
