From: Linus Luessing linus.luessing@web.de
This parameter can be set individually on each interface and allows the configuration of the ndp interval for the link quality measurements during runtime. Usually it is desirable to set it to a higher (= slower) value on interfaces which have a more static characteristic (e.g. wired interfaces) or very dense neighbourhoods to reduce overhead.
Developed by Linus during a 6 months trainee study period in Ascom (Switzerland) AG.
