We're building up new datecenter network as follows:
- two interconnected cat6509/sup720 which will handle the core network (web services, mail, datacenter operation, and client access).
- two dedicated, interconnected cat6504/sup32 which will handle our business-critical applications.
The former t?pically handle many changes during their life, in term of access VLAN, ACLs, PBR, QoS.
The latter are dedicated, and, as such, they would be less involved into changes.
Furthermore, they should be able to run even if core switches are BOTH down.
STP storms should not affect the operation of these ones.
They are all connected via FO, the couples w/ a pair of Gigabit L2 etherchannel links,
and a full mesh between the two couples, to have better.
Any suggestion on best setup for connecting the two couples, and on general configuration?
