I am upgrading my 6509 chassis with 2 Sup720/MSFC. I am currently running single SupII/MSFC with HSRP between the 2 MSFC. I am a little confused on setting up dual MSFC's. Will the vlan interface IP's be identical on each MSFC in the same chassis? I think I understand the HSRP with the priorities with each vlan interface having a different priority.
