NETWORKING 2 LESSON 2

subnetting

The practice of dividing a network into two or more networks is

called —-

subnet

a logical subdivision of an IP network.

subnetting

a method for getting the most out of the limited 32-bit IPv4

addressing space and reducing the size of the routing tables in a large internetwork.

subnet mask

screen of numbers used for routing traffic within a subnet.

classless interdomain routing

cidr meanig

network id

First address of subnet is called

block size

the size of subnet including network address, hosts addresses and

broadcast address.

direct and local broadcast

two types of broadcast

direct or local broadcast

last address of subnet and can be hear by

all hosts in subnet.

full broadcast

the last address of IP classes and can be hear by all IP hosts in

network.

host address

All address between the network address and the directed broadcast address is called

binary anding

s the process of performing multiplication to two binary numbers

enhanced bob manuever

• a method of subnetting any address using a special chart. 

VARIABLE LENGTH SUBNET MASKING

VLSM MEANING

VLSM

• is the more realistic way of subnetting a net-work to make the most efficient use of all of the bits.

ROUTE FLAPPING

• s when a network, for whatever reason (such as interface hardware failure or misconfiguration), goes up and down on a router, causing that routes to constantly advertise changes about that network.

ROUTE FLAPPING

is a networking issue where the state of a router constantly fluctuates within a short period of time

ROUTE FLAP DAMPENING

is a technique that enables network administrators to stabilize the network routes in case a router flaps.
