Replying to my own post to provide a bit more info. Doing a tcpdump on another box on the same LAN, I captured this when I fail the director from my spare box (lvs3) to the primary box (lvs2):

That MAC is eth0 on lvs2, the box that's just now obtaining the VIP. Alas, I still can't ping the VIP from the remote box that performed the packet dump:

# ping lvs-vip1
