Huafeng, 

Okay, I think see that what your are saying is in the context of VRRP,
and in that sense I can agree.  But "primary IP address" is (imho, far)
more widely used and I was thinking about those semantics, so I prefer
not to try to extend this concept as I think the confusion would
outweigh the benefit.  

Opinion from others on the list? 

Thanks,
Steve
