Good day, now I have two 6500 switches as CORE, interconnected with PortChannel, I connect a VG224 which has 2 FastEthernet ports and an interface Loopback0, copper ports every 6500, I would like to have redundancy in L3 through OSPF, but unsubscribe when the interface which is connected to the VG224 6500th comunicacion.y lose him no redundancy 6500B, as someone could help achieve redundancy????
