DCI

hi,

there are 3 DC's and we are in process of making them interconnect with dark fiber..we have 6500 and 7600 and would like to have nexus 7000 as core layer. can we 6500 and 7600 as core(7600) and aggregation layers(6500 with sup-2t) for exp eompls between DC's..

is it better to run 6500 VSS within DC and run Nexus 7K for DC interconnect(OTV)..

since we already have 6500, so with sup-2t EoMPLS and VSS within and accross the DCI over OTV..does this make sense..

core being Nexus 7K and Aggregation being 6500 in all 3 DC's..

thanks

GP
