zfs snapshot [-r] [-o property=value] ... filesystem@snapname|volume@snapname

Creates a snapshot with the given name. All previous modifications by successful system calls to the file system are part of the snapshot. See the “Snapshots” section for details.

-r

Recursively create snapshots of all descendent datasets. Snapshots are taken atomically, so that all recursive snapshots correspond to the same moment in time.

IPv6 defines three address types:

unicast

Identifies an interface of an individual node.

multicast

Identifies a group of interfaces, usually on different nodes. Packets that are sent to the multicast address go to all members of the multicast group.

anycast

Identifies a group of interfaces, usually on different nodes. Packets that are sent to the anycast address go to the anycast group member node that is physically closest to the sender.
