Activity Questions Lab 8.1
Broadcasts periodically
RIP
Uses multicasting
RIPv2, EIGRP, OSPF
Uses multicast address 224.0.0.10
EIGRP
Uses multicast address 224.0.0.9
RIPv2
Uses multicast address 224.0.0.5
OSPF
May elect a DR
OSPF
Uses LSAs
OSPF
Is actually a hybrid routing protocol
EIGRP
Limited to 15 hops
RIP, RIPv2
Cisco proprietary
EIGRP
Auto-summarizes at major network boundaries
RIP, RIPv2, EIGRP
Calculates a feasible successor
EIGRP
Uses the Dijkstra algorithm
OSPF
Uses the DUAL algorithm
EIGRP
Classful
RIP
Classless
RIPv2, EIGRP, OSPF
Has the ability to authenticate
RIPv2, EIGRP, OSPF
Uses PDMs to support multiple protocols such as
IPX and AppleTalk
EIGRP
Uses Hello packets to establish adjacencies
EIGRP, OSPF
Open standard
RIP, RIPv2, OSPF
Uses cost as its only metric
OSPF
Review Questions Lab 8.1
1. What can classless routing protocols do that classful routing protocols cannot?
2. What is an advantage of OSPF over EIGRP?
3. What is an advantage of EIGRP over OSPF?
4. Why might you have to turn off the auto-summarization feature?
5. Why is multicasting rather than broadcasting generally preferred for routing updates?
Activity Questions Lab 8.2
12. No
14. Yes, RIPv2 should be sending and receiving updates on all interfaces that are
2
18. Should be s0/0, s0/1, or f0/0
Review Questions Lab 8.2
1. What command tells the router to listen for and advertise RIPv2 instead of RIPv1?
2. What is the advantage of RIPv2 over RIPv1?
3. What is the disadvantage of RIPv2?
4. What command tells an interface on a router to listen for but not send routing updates?
5. True or False? RIPv1 and RIPv2 default timers are identical.
Activity Questions Lab 8.3
10. D; 90
12. Successors; depends on which router is being configured
Review Questions Lab 8.3
1. Why didn’t you need the no auto-summary command in this lab?
2. What is in the EIGRP topology table?
3. True or False? EIGRP is a hybrid routing protocol based on link-state technology.
Activity Questions Lab 8.4
13. It will be the IP address of the OSPF interface; varies
17. Lab-e; lab-d
20. Lab-e; lab-d
Review Questions Lab 8.4
1. What extra parameters are necessary in the network command when using OSPF,
as compared with RIP, RIPv2, and EIGRP?
2. What is the purpose of areas in OSPF?
3
3. What is the purpose of the DR?
4. What determines which router will be the DR?
5. What are the two steps involved when configuring OSPF authentication?
