So, if I understand the description on that page, you could define a
host something like this...

define host{
	host_name	router1.example.com
	alias		Router #1
	address		fa0-0,192.168.1.1,fa0-1,192.168.2.1
	check_command	check-router-interfaces
	}

So, the whole address string would get passed to the plug-in via the
$HOSTADDRESS$ macro.

Then, for the `check-router-interfaces` plug-in, you split the
$HOSTADDRESS$ into pairs... interface name and IP address.  If all
interfaces are reachable and reply to the query (ping, for example),
then the host is 'OK'.  If all are down, then the host status is
'CRITICAL'.  If one or more, but less than all, are down, then it is
'WARNING'.

This is interesting, as I have up until now been using individual host
entries for each interface that I want to monitor
(fa0-0.router1.example.com, fa0-1.router1.example.com, etc.) and this
seems like it might be... better?

Hmm... wouldn't this also work for service checks?

Or, did I totally miss the point the OP was trying to make?  :)
