NAME

Distance Vector Routing Protocols

Question
Answer
1
What does RIP stand for?
Routing Information Protocol
2
What metric does RIP use for Path Selection?

Hop count
3
If the metric used by RIP exceeds this value for a route it is considered unreachable, effectively making this value appear to be infinity to RIP?
16
4
How often does RIP send updates by default (update timer)?
Send full updates every 30 seconds

5
What are the main differences between RIPv1 and RIPv2? the main difference between RIPv1 and RIPv2 is classless routing. RIPv2 incorporates the addition of the network mask in the update to allow classless routing advertisements. This is extremely important for the flexibility needed to efficiently utilize network assignments for an ever-shrinking pool of IP addresses.
6
What is convergence and why is it important?
Automated mapping and integration of information technology environments available to a user
7
Is RIP considered to be a fast or slow converging protocol? slow For the simple 3 router network (Figure 1), fill in the information that would be in each router’s routing table once the network has converged (see example in Chapter 4, pages 192-193).
