Now my question is , weather the ports for 3 hosts (pc1, pc2 and pc3)
of switch 2 are also became designated port.
And why????

Yes. Every active port (i.e., a port onto which frames are forwarded by
a switch) is either a Designated Port or a Root Port. Each Designated
Bridge (switch) has one (and only one) Root Port, plus one or more
Designated Ports.

While it is difficult to see your true topology (due to the ASCII art,
which is still not aligned in my screen view), Switch 2 in your drawing
is apparently a Designated Bridge, with its Root Port connected to
Switch 1 (the Root Brodge), and a number of Designated Ports, three of
which connect to PC1, PC2, and PC3.

I hope this helps.

Hello,


As some switches support MSTP, Some others support RSTP ,, so is
that
switches are also compatible with those switches , which support only
STP (IEEE 802.1d).


If it is possible then please also tell me ...
Is any bits to be set for providing the compatiblity with those
switches which support MSTP or RSTP , with switch which support only
simple STP.
or it done automatically by switch hardware.


Thanks in advance.


Vikrant
