	We've been having a problem with the bridging
	configuration in our ciscos and how it relates to our 
	other bridges (DEC, Retix, Allied Telesis, Cabletron).
	We are running version 8.0 (10) of the cisco firmware,
	and we're using the DEC spanning tree protocol option.

	Since our network topology contains routing loops, we 
	need to have our ciscos compute a spanning tree. However,
	since our ciscos and non-cisco bridges are not really
	peers, we don't want the ciscos to disable any of our
	other (non-cisco) bridges (which they attempt to do in
	the presence of loops). 

	Is there a way to isolate the cisco's spanning tree from
	the other (non-cisco) bridges?. That is, can we have the
	ciscos use the only the other ciscos in their spanning
	tree computations, while the non-cisco bridges use only
	other non-cisco bridges in their spanning tree
	computations? Is there a better solution to this problem? 

	Thanks,


	Dave
