Right now we have one 6509 switch with MSFC2 that serves as a core switch and server farm switch. All access switches have a L2 trunk link to the 6509. All servers also connect to the same switch.
I am planning to upgrade to sup720 and add another 6509 for redundancy. All new access switches will have dual L3 link to two 6509 switches. Servers will have dual NIC to connect to both 6509.
Look like the only choice that I have is to configure a L2 trunk link and HSRP for the server subnet between two 6509. Dual NIC will be in the same VLAN.
can I configure a L3 link between two 6509 and still have dual home servers?
I really appreciate for any information or feed back if you have a similar setup.
