ARP reply control

Could someone please outline how to use iproute2 to ensure an LVS
director with multiple network interfaces only sends ARP replies with
the MAC address of the interface associated with a service's VIP?

Our main director system usually responds with the MAC address of
eth0, even for a VIP which is on eth1. It's running kernel 2.4.2 with
ipvs-0.2.11.

I'm experimenting with our backup director, using kernel 2.4.5 and
Julian's noarp-2.4.5-1.diff patch for "per-route ARP handling", and
the iproute2-noarp-1.diff patch applied to
iproute2-2.2.4-now-ss001007.tar.gz.  Even after reading the Linux 2.4
advanced routing howto, I realise I'm not sure how to get the
behaviour I want.

thanks
