Support for IPv6 Identifier Locator Addressing (ILA).
|
|
|
|
ILA is a mechanism to do network virtualization without

|
encapsulation. The basic concept of ILA is that we split an
|
|
IPv6 address into a 64 bit locator and 64 bit identifier. The
|
|
identifier is the identity of an entity in communication
|
|
("who") and the locator expresses the location of the
|
|
entity ("where").
|
|
|
|
ILA can be configured using the "encap ila" option with
|
|
"ip -6 route" command. ILA is described in
|
|
https://tools.ietf.org/html/draft-herbert-nvo3-ila-00.

IPv6 Rapid Deployment (6rd; draft-ietf-softwire-ipv6-6rd) builds upon
|
|
mechanisms of 6to4 (RFC3056) to enable a service provider to rapidly
|
|
deploy IPv6 unicast service to IPv4 sites to which it provides
|
|
customer premise equipment. Like 6to4, it utilizes stateless IPv6 in
|
|
IPv4 encapsulation in order to transit IPv4-only network
|
|
infrastructure. Unlike 6to4, a 6rd service provider uses an IPv6
|
|
prefix of its own in place of the fixed 6to4 prefix.
|
|
|
|
With this option enabled, the SIT driver offers 6rd functionality by
|

providing additional ioctl API to configure the IPv6 Prefix for in

stead of static 2002::/16 for 6to4.

Tunneling means encapsulating data of one protocol type within

|
another protocol and sending it over a channel that understands the

|
encapsulating protocol. This particular tunneling driver implements
|
|
GRE (Generic Routing Encapsulation) and at this time allows
|
|
encapsulating of IPv4 or IPv6 over existing IPv6 infrastructure.
|
|
This driver is useful if the other endpoint is a Cisco router: Cisco
|
|
likes GRE much better than the other Linux tunneling driver ("IP
|
|
tunneling" above). In addition, GRE allows multicast redistribution
|
|
through the tunnel.
