The **gnt-network** command is used for network definition and

administration in the Ganeti system. Each instance nic can be connected

to a network via the ``network`` nic parameter. See **gnt-instance**\(8)

``--gateway6`` options. IP pool is meaningless for IPV6 so those two
51 53
values can be used for EUI64 generation from a NIC's MAC address.

Note that a when connecting a network to a node group (see below) you
56
can specify also the nic mode and link that will be used by instances on
57
that group to physically connect to this network. This allows the system
58
to work even if the parameters (eg. the VLAN number) change between
59
groups.
