The Junos OS enters the Neighbor Discovery Protocol (NDP) packets into the routing platform cache even if there is no known route to the source.

If you are using Virtual Router Redundancy Protocol (VRRP) for IPv6, you must include the virtual-router-only statement on both the primary and backup VRRP on the IPv6 router.

The remaining statements are explained separately. See CLI Explorer.
