Examples—New ifconfig Command Options
The following usage of the ifconfig command creates
the hme0:3 logical interface to the 1234::5678/64 IPv6
address. This command enables the interface with the up
option. The command also reports status. The command disables the interface.
Finally, the command deletes the interface.
Example 3–1 Examples—Using addif and removeif
# ifconfig hme0 inet6 addif 1234::5678/64 up
Created new logical interface hme0:3
# ifconfig hme0:3 inet6
hme0:3: flags=2000841<UP,RUNNING,MULTICAST,IPv6> mtu 1500 index 2
inet6 1234::5678/64
# ifconfig hme0:3 inet6 down
# ifconfig hme0 inet6 removeif 1234::5678
|
The following usage of the ifconfig command opens
the device that is associated with the physical interface name. The command
configures the streams that are needed for TCP/IP to use the device. The command
reports the status of the device. The command configures the source and the
destination address for the tunnel. Finally, the command reports the new status
of the device after the configuration.
Example 3–2 Examples—Using tsrc, tdst,
and index
# ifconfig ip.tun0 inet6 plumb index 13
# ifconfig ip.tun0 inet6
ip.tun0: flags=2200850<POINTOPOINT,RUNNING,MULTICAST,NONUD,
#IPv6> mtu 1480 index 13
inet tunnel src 0.0.0.0
inet6 fe80::/10 --> ::
# ifconfig ip.tun0 inet6 tsrc 120.46.86.158 tdst 120.46.86.122
# ifconfig ip.tun0 inet6
ip.tun0: flags=2200850<POINTOPOINT,RUNNING,MULTICAST,NONUD,
IPv6> mtu 1480 index 13
inet tunnel src 120.46.86.158 tunnel dst 120.46.86.122
inet6 fe80::8192:569e/10 --> fe80::8192:567a

Example 3–3 Configuring 6to4 Through ifconfig—Long Form
# ifconfig ip.6to4tun0 inet6 plumb
# ifconfig ip.6to4tun0 inet tsrc 129.146.86.187 \
2002:8192:56bb:1::8192:56bb/64 up
|
# ifconfig ip.6to4tun0 inet6
ip.6to4tun0: flags=2200041<UP,RUNNING,NONUD,IPv6>mtu 1480 index 11
inet tunnel src 129.146.86.187
tunnel hop limit 60
inet6 2002:8192:56bb:1::8192:56bb/64
|
This example of the 6to4 pseudo-interface configuration uses the subnet
ID of 1 and also specifies the host ID, in hexadecimal form.
Example 3–4 Configuring 6to4 Through ifconfig—Short Form
# ifconfig ip.6to4tun0 inet6 plumb
# ifconfig ip.6to4tun0 inet tsrc 129.146.86.187 up
|
# ifconfig ip.6to4tun0 inet6
ip.6to4tun0: flags=2200041<UP,RUNNING,NONUD,IPv6>mtu 1480 index 11
inet tunnel src 129.146.86.187
tunnel hop limit 60
inet6 2002:8192:56bb::1/64
