Hi Guys,
This appears to be just a tiny bug, here are the details and how you can replicate it.
I just created a custom interface list with some customer facing interfaces in it.
I then set the Neighbour discovery to !ListName
Then I exported the discovery settings (ready to setup on multiple other routers)
ip neighbor discovery-settings export
When you do the export, it misses the “!”. Which in fact reverses the rule you created.
Thanks guys
