208 | Tunneling means encapsulating data of one protocol type within | ||
209 | another protocol and sending it over a channel that understands the | ||
210 | encapsulating protocol. This particular tunneling driver implements | ||
211 | GRE (Generic Routing Encapsulation) and at this time allows | ||
212 | encapsulating of IPv4 or IPv6 over existing IPv6 infrastructure. | ||
213 | This driver is useful if the other endpoint is a Cisco router: Cisco | ||
214 | likes GRE much better than the other Linux tunneling driver ("IP | ||
215 | tunneling" above). In addition, GRE allows multicast redistribution | ||
216 | through the tunnel. | ||
