169 | IPv6 Rapid Deployment (6rd; draft-ietf-softwire-ipv6-6rd) builds upon | |
170 | mechanisms of 6to4 (RFC3056) to enable a service provider to rapidly | |
171 | deploy IPv6 unicast service to IPv4 sites to which it provides | |
172 | customer premise equipment. Like 6to4, it utilizes stateless IPv6 in | |
173 | IPv4 encapsulation in order to transit IPv4-only network | |
174 | infrastructure. Unlike 6to4, a 6rd service provider uses an IPv6 | |
175 | prefix of its own in place of the fixed 6to4 prefix. | |
176 | ||
177 | With this option enabled, the SIT driver offers 6rd functionality by | |
178 | providing additional ioctl API to configure the IPv6 Prefix for in | |

200 | Tunneling means encapsulating data of one protocol type within | |
201 | another protocol and sending it over a channel that understands the | |
202 | encapsulating protocol. This particular tunneling driver implements | |
203 | GRE (Generic Routing Encapsulation) and at this time allows | |
204 | encapsulating of IPv4 or IPv6 over existing IPv6 infrastructure. | |
205 | This driver is useful if the other endpoint is a Cisco router: Cisco | |
206 | likes GRE much better than the other Linux tunneling driver ("IP | |
207 | tunneling" above). In addition, GRE allows multicast redistribution | |
