255 Tunnel protection directly associates an SA with all packets
256 ingress and egress on the tunnel. This could also be achieved by
257 assigning an SPD to the tunnel, but that would incur an unnessccary
260 For tunnels the ESP acts on the post-encapsulated packet. So if this
265 where O-IP is the overlay IP addrees that was routed into the tunnel,
266 the resulting encapsulated packet will be:
267 +---------+------+------+
268 | Payload | O-IP | T-IP |
269 +---------+------+------+
270 where T-IP is the tunnel's src.dst IP addresses.
271 If the SAs used for protection are in transport mode then the ESP is
272 inserted before T-IP, i.e.:
273 +---------+------+-----+------+
274 | Payload | O-IP | ESP | T-IP |
275 +---------+------+-----+------+
276 If the SAs used for protection are in tunnel mode then another
277 encapsulation occurs, i.e.:
278 +---------+------+------+-----+------+
279 | Payload | O-IP | T-IP | ESP | C-IP |
280 +---------+------+------+-----+------+
281 where C-IP are the crypto endpoint IP addresses defined as the tunnel
