About to add more redundant links to an existing topology.

Hello all,

I am about to add 2 addtional links to an existing spanning tree topology so each distribution switch goes directly into the two cores.  We have 4 6509s,  2 for the core and 2 for distribution.   There are 2 etherchannels from each distribution going straight down to the cores and one etherchannel connecting the the two IDF distribution 6509s together.  I will add two etherchannels diagonally to each core.  So there would be 2 links from each distribution 6509 to each core 6509.  I will then remove the etherchannel between the two distribution 6509s.  What could I expect to go wrong with doing this?

Hi,

Are all these switches layer-2?  Where are the SVIs for all your vlans. In addition, do you also have access layer switches in your network?
