routing protocols : Classful routing protocols

The video tutorial explains classful routing protocols, highlighting their limitations due to the lack of subnet mask advertisement. It discusses the assumptions made by routers regarding subnet masks, which can lead to network inconsistencies. The tutorial also covers the scalability issues of classful protocols and how they summarize routes across classful boundaries. Examples of classful protocols like RIP version one and IGRP are mentioned, emphasizing their obsolescence in modern networks.

Why do classful routing protocols not advertise the subnet mask?

• They automatically detect subnet masks.

• They do not support subnetting.

• They are designed for IPv6 only.

• They assume all networks use the same mask.

What is a potential issue with classful routing protocols assuming network consistency?

• It leads to increased network security.

• It can cause routing errors if subnet masks differ.

• It simplifies network management.

• It enhances network speed.

Which of the following is NOT a classful routing protocol?

• OSPF

• IGRP

• RIP version one

• EIGRP

How do classful routing protocols handle route summarization?

• They do not perform any summarization.

• They summarize routes based on network traffic.

• They summarize routes to the nearest subnet.

• They summarize routes to the classful boundary.

What happens when a classful routing protocol encounters a Class A subnet?

• It ignores the subnet.

• It treats it as a Class B subnet.

• It converts it to a Class C subnet.

• It summarizes it to the classful boundary.
