Template Parameters
client_index- opaque cookie to identify the sender
context- sender context, to match reply w/ request
is_add- add SAD entry if non-zero, else delete
sad_id- sad id
spi- security parameter index
protocol- 0 = AH, 1 = ESP

remote_address_stop- end of remote address range to match
local_address_start- start of local address range to match
local_address_stop- end of local address range to match
protocol- protocol type to match [0 means any] otherwise IANA value
remote_port_start- start of remote port range to match ...
remote_port_stop- end of remote port range to match [0 to 65535 means ANY, 65535 to 0 means OPAQUE]
local_port_start- start of local port range to match ...
local_port_stop- end of remote port range to match [0 to 65535 means ANY, 65535 to 0 means OPAQUE]
policy- action to perform on match
sa_id- SAD instance id (control plane allocated)

typedef ipsec_tunnel_protect
Initial value:
{
vl_api_interface_index_t sw_if_index
vl_api_interface_index_t sw_if_index
Definition: gre.api:50

Add or Update Protection for a tunnel with IPSEC.

Tunnel protection directly associates an SA with all packets ingress and egress on the tunnel. This could also be achieved by assigning an SPD to the tunnel, but that would incur an unnessccary SPD entry lookup.

For tunnels the ESP acts on the post-encapsulated packet. So if this packet: +------—+---—+ | Payload | O-IP | +------—+---—+ where O-IP is the overlay IP addrees that was routed into the tunnel, the resulting encapsulated packet will be: +------—+---—+---—+ | Payload | O-IP | T-IP | +------—+---—+---—+ where T-IP is the tunnel's src.dst IP addresses. If the SAs used for protection are in transport mode then the ESP is inserted before T-IP, i.e.: +------—+---—+--—+---—+ | Payload | O-IP | ESP | T-IP | +------—+---—+--—+---—+ If the SAs used for protection are in tunnel mode then another encapsulation occurs, i.e.: +------—+---—+---—+--—+---—+ | Payload | O-IP | T-IP | ESP | C-IP | +------—+---—+---—+--—+---—+ where C-IP are the crypto endpoint IP addresses defined as the tunnel endpoints in the SA. The mode for the inbound and outbound SA must be the same.

Template Parameters
client_index- opaque cookie to identify the sender
context- sender context, to match reply w/ request
sw_id_index- Tunnel interface to protect
sa_in- The ID [set] of inbound SAs
sa_out- The ID of outbound SA
