That is informative about the problem but out of date wrt the available
fixes.  The arp_filter and arp_announce/ignore patches both provide a
solution but check your kernel to see if they are available (if so, they
should be documented in the ip-syscl.txt file in the kernel docs).
arp_ignore is imho better.  Depending on the level you set it to on
network hosts, you may also need to set arp_announce.

simple to understand it.
