Run commands automatically when bringing up/down network interfaces?
OK.
The next question becomes: how do we ensure that this happens for each defined IP, and that the ping is issued from a given IP address (routing/ etc.).
What we're hoping to accomplish is for the colo switch to get the correct ARP address for each defined IP address on the host. *In some cases, we'll have multiple NICs on the same subnet, in others, IP aliases on the same NIC.

If you look in /etc/sysconfig/network-scripts/ifup, you'll see that it
will call /sbin/ifup-pre-local if it exists, before bringing up the
network interface.
That script also calls .../network-scripts/ifup-post after bringing up
the network interface, which in turn will call /sbin/ifup-local, if it
exists, as its last step.
Neither is interface-specific, but they get the interface name passed to
them, so if you needed to do something different for different
interfaces, you could.
