[c-nsp] Cisco and Juniper learning IPv6 neighbor different behavior

[sthaug at nethelp.no]

> If I generate the traffic once a while, then stop, the neighbour will disappear sometime later or not?

The IPv6 neighbor cache entry will indeed disappear. That's how it's
supposed to work...

> If I configure the GUA and ULA address for the same interface, then generate the traffic, the router will learn both of the neighbours or just one of them?

If it receives traffic from a GUA neighbor address, it will learn that
GUA neighbor.

If it receives traffic from a ULA neighbor address, it will learn that
ULA neighbor.

No magic involved.
