Use this command to disable assignment of IPv6 addresses on all
interfaces.
.. cfgcmd:: set system ipv6 disable-forwarding
Use this command to disable IPv6 forwarding on all interfaces.
.. cfgcmd:: set system ipv6 neighbor table-size <number>
Use this command to define the maximum number of entries to keep in
the Neighbor cache (1024, 2048, 4096, 8192, 16384, 32768).
.. cfgcmd:: set system ipv6 strict-dad
