routing protocols : Auto summarization

The video tutorial explains classful networks, focusing on Class A and B subnets. It discusses how classful routing protocols automatically summarize routes when crossing class boundaries. The tutorial also covers how routers advertise networks and the concept of equal cost paths, which allows for load balancing across different routes. This can lead to some packets succeeding while others fail, depending on the path taken.

What is the primary function of classful routing protocols?

• To prevent data loss during transmission

• To increase the speed of data transfer

• To automatically summarize routes when crossing classful boundaries

• To encrypt data for secure transmission

When a router moves from a Class A network to a Class B network, what does it do with the network advertisement?

• It encrypts the network advertisement

• It summarizes the network advertisement to a classful boundary

• It splits the network advertisement into smaller subnets

• It changes the network advertisement to a Class C network

How does router 2 perceive the network 10.0.0.0 in the given topology?

• As a single path through router one

• As a single path through router three

• As an unreachable network

• As having equal cost paths through both router one and router three

What is the result of router 2 having equal cost paths to a destination?

• All packets are sent to router three

• All packets are sent to router one

• Packets are dropped due to confusion

• Packets are alternately sent to router one and router three

What is the consequence of load balancing across both fast Ethernet 00 and fast Ethernet one?

• The network will become unstable

• All pings will succeed

• All pings will fail

• Half of the pings will succeed and half will fail
