11. Define Routing?
It
is the process of building up the tables that allow thwe collect output for a
packet to be determined.
12. Define ICMP?
Internet
Control Message Protocol is a collection of error messages that are sent back
to the source host whenever a router or host is unable to process an IP
datagram successfully
13. Write the keys for understanding the distance vector routing?
The three keys
for understanding the algorithm are,
·
Knowledge about the whole networks
·
Routing only to neighbors
·
Information sharing at regular intervals
14. Write the keys for understanding the link state routing?
The three keys
for understanding the algorithm are,
·
Knowledge about the neighborhood.
·
Routing to all neighbors.
·
Information sharing when there is a range.
15. How the packet cost referred in distance vector and link state
routing?
In distance
vector routing, cost refer to hop count while in case of link state routing,
cost is a weighted value based on a variety of factors such as security levels,
traffic or the state of the link.
16. Define Reliable flooding?
It
is the process of making sure that all the nodes participating in the routing
protocol get a copy of the link state information from all the other nodes.
17. What are the features in OSPF?
·
Authentication of routing messages.
·
Additional hierarchy.
·
Load balancing.
18. Define Subnetting?
Subnetting
provides an elegantly simple way to reduce the total number of network numbers
that are assigned. The idea is to take a single IP network number and allocate
the IP address with that network to several physical networks, which are now
referred to as subnets.
19. What are the different types of AS?
·
Stub
AS
·
Multi homed AS
·
Transit
AS
20. What is an Area?
An
Area is a set of routers that are administratively configured to exchange
link-state information with each other. There is one special area- the backbone
area, also known as area 0.
