Here subnet mask is 128 i.e. /25 is the CIDR . 1 bit is
used 4 addressing.

Class-C address format is N.N.N.H(8bit.8bit.8bit.8bit)

for subnetting we used cisco rule

1)no of subnet= 2^1=2 ( 1 is the first on bit of last
octate)

2)no. of host in each subnet=2^7=128-2=126( 7 is the off
bit of last octate)

3)valid subnet=256-128=128 i.e. 0, 128

4) broadcast address= is the no. right before the next
subnet

5) valid host= nos. between network address & broadcast
address

below table gives u detail

subnet 0 128

1st valid 1 129
host

last valid 126 253
host

broadcast
address 127 254

Suppose we are having two Switches i.e. Switch1 & Switch2 Port1 of Switch1 is Connected to Uplink and switch2 is also connected to switch1? So 1>Is there is any loop? 2>How we come to know that there is a loop created? 3>If we add Switch3 to switch2 then there is a possibility of loop Creation?
