Routing Protocol Summary

Question 1

What is 6to4?

Answer 1

Mechanism allows IPv6 to be transmitted in IPv4 network

Question 2

What is 1 of the 2 different types of routing protocols?

Answer 2

• Interior
• Interior Gateway Protocol (IGP)
• Operates within autonomous system

Question 3

What is an another type of routing protocol?

Hint: outside

Answer 3

• Exterior
• Exterior Gateway Protocol (EGP)
• Operates between autonomous system

Question 4

What are 2 techniques preventing routing loops?

Answer 4

• Split Horizon
• Prevent route learned from one interface from being advertised back from same interface (TTL and Max Hop Count)
• Poison Reserve
• Caused a route received on one interface to be advertised back from the same interface

Question 5

What is RIPv1?

Answer 5

• Routing Information Protocol
• Interior Gateway Protocol
• Distance Vector, Classful Protocol

Question 6

What is OSPF?

Answer 6

• Open Shortest Path First
• Interior Gateway. Classless Protocol
• A Link State routing protocol that helps direct traffic on IP networks by calculating the most efficient path between routers.
• Open Standard Protocol
• Only protocol support VSLM

Question 7

What is EIGRP?

Answer 7

• Enhanced Interior Gateway Routing Protocol
• Interior Gateway, Classless Protocol
• An Advanced Distance vector that helps routers automatically make routing decisions and configure themselves. Supports convergence and is proprietary to Cisco devices
• Uses the Diffusing Update Algorithm (DUAL)

Question 8

What is IS-IS?

Answer 8

• Intermediate System to Intermediate System
• Interior Gateway, Classless Protocol
• A Link State routing protocol used in computer networks to determine the best path for forwarding packets.

Question 9

What is BGP?

Answer 9

• Border Gateway Protocol
• Exterior Gateway, Classless Protocol
• A Path Vector protocol where a set of rules that determine the best network routes for data transmission on the internet

Question 10

What is RIPv2?

Answer 10

• Routing Information Protocol
• Distance Vector, Classless Protocol
• A distance-vector protocol that is used to manage routing information on networks.

Question 11

What is stub routing in EIGRP?

Answer 11

A feature that improves network stability, reduces resource utilization, and simplifies configuration.

Question 12

What are classless routing protocols?

Answer 12

• EIGRP
• OSPF
• IS-IS
• BGP
• RIPv2

Question 13

What is classful routing protocol?

Answer 13

• RIPv1
• IGRP

Question 14

What protocol has the least overhead of the 4 classless routing protocol?

Answer 14

RIPv2
