because IPv6 addresses configured on the loopback interface must have a 128-bit
prefix length.
Whether this address is the preferred address—Each subnet on an interface has a
preferred local address. If you configure more than one address on the same subnet,
the preferred local address is chosen by default as the source address when you
originate packets to destinations on the subnet. For more information about preferred
addresses, see Configuring Default, Primary, and Preferred Addresses and Interfaces.
By default, the preferred address is the lowest numbered address on the subnet. To
override the default and explicitly configure the preferred address, include the
statement when configuring the address.
Whether this address is the primary address—Each interface has a primary local address.
If an interface has more than one address, the primary local address is used by default
as the source address when you originate packets out the interface where the
destination gives no hint about the subnet (for example, some
more information about primary addresses, see Configuring Default, Primary, and
Preferred Addresses and Interfaces.
By default, the primary address on an interface is the lowest numbered non-127 preferred
address on the interface. To override the default and explicitly configure the preferred
address, include the

You can configure router or switch interfaces with a 32-bit IP version 4 (IPv4) address
and optionally with a destination prefix, sometimes called a subnet mask. An IPv4 address
utilizes a 4-octet dotted decimal address syntax (for example,
with destination prefix utilizes a 4-octet dotted decimal address syntax appended with
a destination prefix (for example,
To configure an IPv4 address on routers and switches running Junos OS, use the
interface interface-name unit number family inet address a.b.c.d/nn

NOTE: Juniper Networks routers and switches support
when used in point-to-point Ethernet configurations; however, they are not
supported by many other devices, such as hosts, hubs, routers, or switches.
You must determine if the peer system also supports
before configuration.
You represent IP version 6 (IPv6) addresses in hexadecimal notation using a
