ip-token - tokenized interface identifier support

ip token { COMMAND | help }

ip token set TOKEN dev DEV

ip token del dev DEV

ip token get [ dev DEV ]

ip token [ list ]

IPv6 tokenized interface identifier support is used for assigning well-known host-part addresses to nodes whilst still obtaining a global network prefix from Router advertisements. The primary target for tokenized identifiers are server platforms where addresses are usually manually configured, rather than using DHCPv6 or SLAAC. By using tokenized identifiers, hosts can still determine their network prefix by use of SLAAC, but more readily be automatically renumbered should their network prefix change [1]. Tokenized IPv6 Identifiers are described in the draft [1]: <draft-chown-6man-tokenised-ipv6-identifiers-02>.

delete the interface token from the kernel.

the networking interface.

show a tokenized interface identifier of a particular networking device. Arguments: coincide with the arguments of ip token set but the TOKEN must be left out.

list all tokenized interface identifiers for the networking interfaces from the kernel.
