Thanks for all your thoughts... and I agree with you all. Actually i
am working on a proposal, where the customer has recommended a ring
with 30 switches.
Of course, i am yet to talk to the customer, but before that, i would
like to make sure, that it is not a good idea to connect so many
switches in a ring..
Btw, the dia of 7 is probably a limit only for STP. With RSTP, we can
go for more.. It works well with 12 switches... Want to know, if
anyone has done more ... :-)
