Examples—New ifconfig Utility 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 16–1 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 16–2 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
