      Hello,
      I need more than 256 CARP Virtual IP because I have many interface.
      Can I duplicate VHID group in CARP VirtualIP if the duplicata is not on the same interface ?

        @BenGonGon to reference an old thread CARP VHID question :

        "Yes, it only has to be unique on each layer 2.

        So long as the multicast traffic from CARP does not cross into the other segments, the same VHID can be used on separate interfaces."

            Yes, as long as they are not on the same layer 2 broadcast domain. Different VLANs can have the same CARP VHID and I guess you should not have multicast forwarding from one VLAN to another.
