Understanding IPv6 Neighbours

Hi, can somebody help me understand the purpose of an IPv6 neighbour? On my switch i can see a few different IPv6 neighbour states, for example STALE and REACH. If my neighbour state is STALE does this mean traffic between this two devices will fail until the status is in REACH? For example I have BGP running between peers over an IPv6 network, would BGP peer fail if the neighbour state is in a STALE state.

Last of all, does anybody have a copy or an example of an access-lists required for an IPv6 neighbour relationship to be established?

Cheers,

You can have a look at the different states and their explanation:

As for ACL and neighbors.

Have a look about the implicit rules (allowing NS and ND).
