What I do here, and what I've seen done elsewhere is to make the DNS name 
for the primary loopback address be something like device.sub.domain.com. 
If you have other loopbacks for other reasons, then they could become 
lo1.device.sub.domain.com, l02.device...  Things like syslog messages, 
SNMP traps, Netflow exports, etc, are sourced from that primary loopback 
address where possible.

As always... ymmv.

As another poster mentioned, discussions about naming conventions can 
often get religious, but when you get down to the heart of it, there are 
no wrong answers.

I've designed conventions in the past, and I've generally tried to make 
them useful to the people who actually need to use them on a regular basis 
(NOC, network engineers, field techs, etc), but it's up to you to come up 
with something that is right for your network.
