10 - Implementing EIGRP

Question 1

What show cmds verify the network statements in EIGRP

Answer 1

• show ip eigrp interfaces
• show ip eigrp interfaces detail
• show ip eigrp interface fa0/0
• show ip protocols

Question 2

What show cmds verify EIGRP neighbors?

Answer 2

• show ip eigrp neighbors
• show ip eigrp neighbors fa0/0
• show ip protocols

Question 3

What show cmds verify EIGRP topology?

Answer 3

• show ip eigrp topology
• show ip eigrp topology /
• show ip eigrp topology | sec

Question 4

What show cmds verify EIGRP routes?

Answer 4

• show ip route
• show ip route eigrp
• show ip route
• show ip route | sec

Question 5

What show cmd verifies EIGRP timers per interface?

Answer 5

show ip eigrp interfaces detail fa0/0

Question 6

For EIGRP what is the default Hello interval?

Answer 6

5 seconds

Question 7

For EIGRP what is the default Hold interval?

Answer 7

15 seconds or 3 times the Hello interval.

Question 8

In EIGRP, what is the default number for Maximum Paths?

Answer 8

4

Question 9

What does the ‘Variance’ command do?

Answer 9

It takes the Feasible Distance and multiplies it by the number in the Variance command. Any Feasible Successor route whose metric falls below the FD times the Variance is considered an equal cost path.

Question 10

When configuring the Delay on an interface what is the value used in the command?

Answer 10

Tens of microseconds. So ‘delay 123’ = 1230 microseconds

Question 11

What command would display the delay on an interface?

Answer 11

show interfaces fa0/1

Question 12

What command would change the EIGRP Hello interval

Answer 12

interface subcommand “ip hello-interval eigrp

Question 13

What command would change the EIGRP Hold timer

Answer 13

interface subcommand “ip hold-time eigrp
