I am currently using exactly the same approach with CARP as described in a prior posting to the stable mailing list, https://groups.google.com/forum/#!topic/mailing.freebsd.stable/-NiHmBWMulY .
I have noticed in my router lab that the MASTER goes into BACKUP mode briefly whenever a new alias participating in the CARP is added or removed.
This happens irrespective of whether the second host of the CARPed pair is down.
Is there a way to avoid this bump or am I stuck with a brief break in service while adding or removing aliases ?
To put this question another way... what is the smoothest way to introduce a new alias into a multi-address vhid group ?
