216 IP Addressing
The following is an example of a CLI script to create a tunnel:
IPv6 Neighbors
The IPv6 Neighbors feature is similar in functionality to the IPv4 Address
Resolution Protocol (ARP) feature. It enables detecting Link Local addresses
within the same subnet, and includes a database for maintaining reachability
information about active neighbors.
The device supports a total of up to 64 neighbors, obtained statically or
dynamically.
When removing an IPv6 interface, all neighbors entered statically or learned
dynamically, are removed.
