i am planning to extend layer 3 to my access switch. i have 6 4506 on the access layer with uplink gig to each my 6509 core/distribution. my plan on my core/distribution cisco 6509 switch with sup 720 is to trunk both 6509. my question is: is their any company that's running this type of setup? if so, what is the caveat with this design.
my design is 2 6509 switch trunk together, 6 4506 switch with layer 3 (routed) link to my 6509.
