EIGRP Routing Protocol Q/A's

Question 1

What does EIGRP stand for?

What type of routing protocol is EIGRP?

Answer 1

Enhanced Interior Gateway Routing Protocol

Advance Distance Vector Routing Protocol

Question 2

What multicast address does EIGRP use to send hello messages?

Answer 2

224.0.0.10

Question 3

What is EIGRP default routing behavior?

Answer 3

equal cost load balancing up to 4 paths

Question 4

Is EIGRP capable of performing unequal cost load balancing? Yes/No

Answer 4

Yes

Question 5

What does EIGRP use in order to peer with other routers?

Answer 5

Autonomous System Number (AS)

Question 6

What type of ID does EIGRP use to identify itself to other routers?

Answer 6

Router ID (RID)

Question 7

What metric value does EIGRP uses to determine a successor router, is it the highest or lowest metric?

Answer 7

lowest metric

Question 8

When the successor router is down and there is not a feasible successor, what happens next?

Answer 8

EIGRP queries other peers routers until a feasible successor is selected

Question 9

When the successor router goes down and a backup feasible successor “does” exist what happens?

Answer 9

immediately fails over without sending a query to the other routers

Question 10

The feasible successor is determined when reported distance is higher or lower than feasible distance of current successor route?

Answer 10

lower

Question 11

What four metrics in EIGRP are used to calculate the successor and feasible successor?

Answer 11

Bandwidth
Delay
Reliability
Load

Question 12

What two metrics in EIGRP are used by default to calculate the successor and feasible successor?

Answer 12

Bandwidth and Delay

Question 13

What two metrics are not recommended to use in the metric calculations?

Answer 13

Reliability

Load

Question 14

When using EIGRP the bandwidth and delay will not change the physical properties of any interface? True/False

If bandwidth and delay are changes it impacts what?

Answer 14

True

software policies and it’s metrics
