another way is to use subdomains to separate device, geographic area, 
and primary function so that a core router in Washington DC might look 
like this:

core-1.wdc.infrastructure.net

this would be a subdomain as well as it would interfaces under it as 
well and possibly sub-interfaces. if you're thinking that this could 
make the FQDM be quite long...you're right...but one advantage is to be 
able to do a "dig axfr" on the sub to see all of the devices in a 
specific location such as "dig wdc.infrastructure.net axfr" would return 
all of the devices in that geographic location. Then you could dig on a 
specific device (as a subdomain) to see all of the interfaces configured 
on that device. This can lead to lots of admin overhead but some good 
scripts to automate it...it works. of course this is just my opinion.

If your managment system only works from a set domain (i.e. xyz.abc.net--abc being your company and xyz being a subsection) then that label xyz should only have dashes and not periods, otherwise they become a domain themselves.
