EXPECTED RESULTS
All 15 records should generate a record in the parse output.
ACTUAL RESULTS
We only see 4 devices out of the 15. I cannot see a difference in the records that work and those that do not so I'm not sure if it is a regex parsing error or something else causing the records to not all show up.

Related to Issue #1166 (where it is the brief output and this is the detailed)
Update: Related as in they both pertain to LLDP template, but that's it. :roll_eyes: :man_facepalming:
@IamBuldog I see several backslashes in the sample output and labels for output lines that appear they're missing. Is there an issue with the sample output?

Vlan ID: not advertised
So far the only thing I've noticed is that for some neighbors MGMT_ADDRESS and/or VLAN_ID are not being parsed (possibly because they show up as "not advertised").
Edit: I do not experience an error with either your sample output nor your sample Python code. Both parse without error. Maybe something came along that fixed this since December 2022?
@mjbear - It's possible something has fixed this in newer versions, I haven't tested recently. I'll update to the latest instance of ntc-templates and re-run script using a direct pull from our production switches to test. It'll take a few days bit to do that but I'll try to reply before Jan 20.
