Flashcards in 3-8: EIGRP Advanced Configurations and Troubleshooting Deck (20):
1

Which command can be issued on a router to verify that automatic summarization is enabled?

show ip protocols

2

Which address best summarizes the IPv6 addresses 2001:DB8:ACAD::/48, 2001:DB8:9001::/48, and 2001:DB8:8752::/49?

2001:DB8:8000::/34

3

In which IOS CLI mode must a network administrator issue the maximum-paths command to configure load balancing in EIGRP?​

router configuration mode

4

Two routers, R1 and R2, have established an EIGRP neighbor relationship, but there is still a connectivity problem. Which issue could be causing this problem?​

an access list that is blocking advertisements from other networks

5

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

when the routers in an IPv4 network are connected to discontiguous networks with automatic summarization enabled

6

Two routers, R1 and R2, share a 64 kb/s link. An administrator wants to limit the bandwidth used by EIGRP between these two routers to 48 kb/s. Which command is used on both routers to configure the new bandwidth setting?

ip bandwidth-percent eigrp 100 75

7

What is a characteristic of manual route summarization?

reduces total number of routes in routing tables

8

The _____________ command causes an EIGRP router to stop sending hello packets through an interface.

passive-interface

9

What is the command that should be issued on a router to verify that EIGRP adjacencies were formed?​

show ip eigrp neighbor

10

You would use what command to verify auto summarization?

show ip protocols

11

What interface discards any packets received?

Null0

12

True / False: You must first configure a Null0 interface before you may use it?

False

13

EIGRP does not use the same command to propagate default routes, it uses what command instead?

redistribute static

14

You see a route in your routing table that starts with "D*EX" what the heck does that even mean?

• D – This route was learned from an EIGRP DUAL
• * – This route is a candidate for a default route.
• EX – External route, in this case a static route.
• 170 – The AD of an external EIGRP route.

15

By default, EIGRP uses up to ____% of bandwidth for EIGRP info.

50%

16

True / False: You would use the command "ip hold-interval eigrp " to change the hold timer?

False, the command is hold-time, not hold-interval

17

The default EIGRP load balancing is on up to _ equal-cost paths.

4

18

What command allows EIGRP to balance traffic across routes with different metrics?

variance

19

What does it mean if your Variance level is 1?

Only routes with the same metric are installed.

20

What does it mean if your Variance level is 1?

Only routes with a metric less than 2x the successor.
