ifconfig(1M) ifconfig(1M)
broadcast (inet only) Specify the address that represents broadcasts to the network.
The default broadcast address is the address with a host part of all 1’s.
encaplimit n
Specify the tunnel encapsulation limit value n. The tunnel encapsulation
limit is the maximum number of additional encapsulations permitted for
the packets. The tunnel encapsulation limit option is defined in RFC 2473.
This option is valid only for tunnel types
ipinip6 and ip6inip6. The
default is 4.
forward (inet6 only) Enable forwarding of packets by this interface. This is the
default behavior.
-forward (inet6 only) Disable forwarding of packets by this interface.
metric n Set the routing metric of the interface to n. The default is 0. The routing
metric is used by the routing protocol (see gated(1M)). Higher metrics have
the effect of making a route less favorable; metrics are counted as addi-
tional hops to the destination network or host.
netmask mask
(inet only) Specify how much of the address to reserve for subdividing net-
works into sub-networks or aggregating networks into supernets. mask
can be specified as a single hexadecimal number with a leading 0x, with a
dot-notation Internet address, or with a pseudo-network name listed in the
network table (see networks(4)).
For subdividing networks into sub-networks, mask must include the net-
work part of the local address, and the subnet part which is taken from the
host field of the address. mask must contain 1’s in the bit positions in the
32-bit address that are to be used for the network and subnet parts, and 0’s
in the host part. The 1’s in the mask must be contiguous starting from the
leftmost bit position in the 32-bit field. mask must contain at least the
standard network portion, and the subnet field must be contiguous with the
network portion. The subnet field must contain at least 1 bit.
For aggregating networks into supernets, mask must only include a portion
of the network part. mask must contain contiguous 1’s in the bit positions
starting from the leftmost bit of the 32-bit field.
prefix n (inet6 only) n indicates the length of the network prefix associated with this
interface. The primary interface (see Interface Naming subsection given
below) prefix length is always 10, and is not configurable. The prefix option
can be used only with the address option, and only for secondary interfaces.
Default: 64. Range: 1 to 128.
private (inet6 only) Enable processing of received router advertisements. Secon-
dary address(es) will be autoconfigured on the interface using the prefix(es)
received in router advertisement(s). This is the default behavior.
-private (inet6 only) Disable processing of received router advertisements.
tunnel type Specify the type of tunnel. The tunnel types can be ip6inip, ipinip6,
ip6inip6, and 6to4.
tdst addr Specify the destination addr of the tunnel. This is the destination address
in the encapsulating (outer) header. It should be an address configured on
an interface on the tunnel exit-point node. For tunnel types ipinip6 and
ip6inip6, the addr should be an IPv6 address. For tunnel type
ip6inip, the addr should be an IPv4 address; and for tunnel type 6to4,
the tdst parameter should not be specified.
tsrc addr Specify the source addr of the tunnel. This is the source address in the
encapsulating (outer) header. It should be an address configured on an
interface in the tunnel entry-point node. For tunnel types ipinip6 and
ip6inip6, the addr should be an IPv6 address. For tunnel types
ip6inip and 6to4, the addr should be an IPv4 address.
