Gah. Then *why* is it documented as such?
http://www.linuxvirtualserver.org/Joseph.Mack/HOWTO/LVS-HOWTO.arp_problem.html
4.2. The cure(s)
[...]
4.2.4. Put an extra NIC on the realserver to carry the VIP (on eth1)
Possible cards would be a discarded ISA card (WD80x3), or a cheap
100Mbit PCI card (eg Netgear FA310TX, $16 in USA in Nov 99) There is
no traffic going through this NIC and it doesn't matter that it's an
old slow card. The extra card is only required so that the
realserver can have the VIP on the machine. With 2.2.x kernels you
can't stop this device (eth1) from replying to arp requests, but if
you don't connect the cable to it or don't put a route to it in the
realserver's routing table, then the client won't be able to send it
an arp request.
It seems to me that that says eth1/VIP is a simple fix, no?
It makes perfect sense that if the docs are wrong, I'm going to be
wrong following them. :-)
