SEMESTER 2 Chapter 7
RIPv2
V 4.0
7.0.1.1 Why has RIP lost favor as
opposed to other protocols?
RIP lacks the capabilities of many of the later protocols.
When is RIP a desirable
protocol?
Its sheer simplicity and widespread use in multiple
operating systems makes it an ideal candidate for
smaller, homogeneous networks where multi-vendor
support is necessary - especially within UNIX
environments.
What are the enhanced
features of RIPv2?
Next-hop addresses included in the routing updates
Use of multicast addresses in sending updates
Authentication option available
What do both versions of RIP
share in features and
limitations?
Use of holddown and other timers to help prevent
routing loops.
Use of split horizon or split horizon with poison reverse
to also help prevent routing loops.
Use of triggered updates when there is a change in the
topology for faster convergence.
Maximum hop count limit of 15 hops, with the hop
count of 16 signifying an unreachable network.
7.1.1.3 What type of address must be
used when a packet is sent
outside your private network?
Public IP address
What subnet mask is used
when only two ip addresses are
needed?
/30
7.1.1.4 What is a loopback interface? A loopback interface is a software-only interface that is
used to emulate a physical interface.
What is a loopback address
used for in the lab setting?
In a lab environment, loopback interfaces are useful in
creating additional networks without having to add
more physical interfaces on the router.
7.1.2.1 What is the command to
establish a supernet route?
R2(config)#ip route 192.168.0.0 255.255.0.0 Null0
What does a supernet route do
to the routing table?
Route summarization allows a single high-level route
entry to represent many lower-level routes, thereby
reducing the size of routing tables.
What are the two
characteristics of a null
interface?
