Flashcards in Routing Protocols Deck (30):
1

What does OSPF use as it's routing metric

Cost

2

What is OSPF cost based on?

Bandwidth

3

Which routing protocol support load balancing over equal cost and unequal cost paths?

EIGRP

4

What command can you use to manually configure OSPF cost of a path to an interface?

ip ospf cost [path cost value]

5

What is used to determine whether EIGRP feasible successors can be used for unequal cost load balancing?

Variance

6

Which routing protocol process ID is locally significant to the router and can be any positive integer from 1 through 65535

OSPF

7

What command do you use to specify OSPF process id ?

router ospf {process id value]

8

What two timer have to match for two routers to forma an adjacency?

Hello and Dead timers

9

what is the command to manually configure the OSPF Hello timer?

ip ospf hello-interval [seconds]

10

What is the command to manually configure the OSPF Dead timer?

ip ospf dead-interval [seconds]

11

What is the default maximum number of equal cost OSPF paths?

4

12

What command can you use to override the default number of equal cost OSPF paths to insert into a routing table?

maximum-paths [maximum value] in OSPF router configuration mode

13

What command is used to specify which interfaces will participate in OSPF and which networks should be advertised?

network command

14

Will routers with different OSPF process IDs establish an adjaceny?

Yes. The OSPF process ID is locally significant to the router.

15

What command is used to specify the OSPF process id?

router ospf [process id]

16

What has to match for two OSPF router to form an adjacency?

Ospf area, Hello timers, and Dead timers

17

In OSPF, What is used to specify the amount of time to wait for hello packets before declaring a neighbor to be down?

Dead timer which is 4 times the hello timer value

18

What is the default value for a Hello timer on a point to point link?

10 seconds

19

What is the default value for a Hello timer on a nonbroadcast multiaccess (NBMA) link?

30 seconds

20

What command is used to view the routing table?

show ip route

21

When will EIGRP not load balance to a route?

Variance is equal to 1 or a route is not considered a successor or feasible successor

22

In EIGRP, what is the best route to a network?

Successor

23

In EIGRP, what is a backup route that can be used if the successor route goes down?

Feasible successor

24

What is the default value of a FastEthernet interface?

10

25

Where are eigrp feasible successor listed?

eigrp topology table

26

what is the command to display the eigrp topology table?

show ip eigrp topology

27

In EIGRP, what are K values sue for ?

to calculate the metric

28

In EIGRP, where are successor routes listed?

routing table

29

What ip address are EIGRP query packets sent to?

multicast address 224.0.0.10

30

If no feasible successors exist, how is a route re-computation initiated?

by sending out multicast query packets
