Answer / jitendera
In A swicth network if you have multiple path that is also
called redundancy then Loop occurs
Now Question is that how a Swicth detect that there is a Loop
Switch uses BUDU to Determine that is there any loop accross
the network
How its works
In a switch network every switch broadcast the BPDU Packet (
BUPDU=MAC+ Bridge)
IF a Switch get his BPDU Back he then switch comes to know
that there is a Loop in the network then STP comes in
accounts
