-VPP as IKEv2 initiator and strongSwan as responder
-==================================================
-
-Prerequisites
--------------
-
-To make the examples easier to configure ``docker`` it is required to pull strongSwan docker image. The networking is done using Linux' veth interfaces and namespaces.
-
-Setup
------
-
-First a topology:
-
-```
-192.168.3.2 192.168.5.2
- + loopback
- | +
-+----+----+ 192.168.10.2 +-----+----+
-| VPP | |strongSwan|
-|initiator+----------------------+responder |
-+---------+ +----------+
- 192.168.10.1
-```
-
-Create veth interfaces and namespaces and configure them:
-
-```
-sudo ip link add gw type veth peer name swanif
-sudo ip link set dev gw up
-
-sudo ip netns add ns
-sudo ip link add veth_priv type veth peer name priv
-sudo ip link set dev priv up
-sudo ip link set dev veth_priv up netns ns
-
-sudo ip netns exec ns \
- bash -c "
- ip link set dev lo up
- ip addr add 192.168.3.2/24 dev veth_priv
- ip route add 192.168.5.0/24 via 192.168.3.1"
-```
-
-
-Create directory with strongswan configs that will be mounted to the docker container
-```
-mkdir /tmp/sswan
-```
-
-Create the ``ipsec.conf`` file in the ``/tmp/sswan`` directory with following content:
-
-```
-config setup
- strictcrlpolicy=no
-
-conn initiator
- mobike=no
- auto=add
- type=tunnel
- keyexchange=ikev2
- ike=aes256gcm16-prfsha256-modp2048!
- esp=aes256gcm16-esn!
-
-# local:
- leftauth=psk
- leftid=@sswan.vpn.example.com
- leftsubnet=192.168.5.0/24
-
-# remote: (gateway)
- rightid=@roadwarrior.vpp
- right=192.168.10.2
- rightauth=psk
- rightsubnet=192.168.3.0/24
-```
-
-``/tmp/sswan/ipsec.secrets``
-```
-: PSK 'Vpp123'
-```
-
-``/tmp/sswan/strongswan.conf``
-```
-charon {
- load_modular = yes
- plugins {
- include strongswan.d/charon/*.conf
- }
- filelog {
- /tmp/charon.log {
- time_format = %b %e %T
- ike_name = yes
- append = no
- default = 2
- flush_line = yes
- }
- }
-}
-include strongswan.d/*.conf
-```
-
-Start docker container with strongSwan:
-
-```
- docker run --name sswan -d --privileged --rm --net=none \
- -v /tmp/sswan:/conf -v /tmp/sswan:/etc/ipsec.d philplckthun/strongswan
-```
-
-Finish configuration of initiator's private network:
-
-```
-pid=$(docker inspect --format "{{.State.Pid}}" sswan)
-sudo ip link set netns $pid dev swanif
-
-sudo nsenter -t $pid -n ip addr add 192.168.10.1/24 dev swanif
-sudo nsenter -t $pid -n ip link set dev swanif up
-
-sudo nsenter -t $pid -n ip addr add 192.168.5.2/32 dev lo
-sudo nsenter -t $pid -n ip link set dev lo up
-```
-
-Start VPP ...
-
-```
-sudo /usr/bin/vpp unix { \
- cli-listen /tmp/vpp.sock \
- gid $(id -g) } \
- api-segment { prefix vpp } \
- plugins { plugin dpdk_plugin.so { disable } }
-```
-
-... and configure it:
-
-```
-create host-interface name gw
-set interface ip addr host-gw 192.168.10.2/24
-set interface state host-gw up
-
-create host-interface name priv
-set interface ip addr host-priv 192.168.3.1/24
-set interface state host-priv up
-
-ikev2 profile add pr1
-ikev2 profile set pr1 auth shared-key-mic string Vpp123
-ikev2 profile set pr1 id local fqdn roadwarrior.vpp
-ikev2 profile set pr1 id remote fqdn sswan.vpn.example.com
-
-ikev2 profile set pr1 traffic-selector local ip-range 192.168.3.0 - 192.168.3.255 port-range 0 - 65535 protocol 0
-ikev2 profile set pr1 traffic-selector remote ip-range 192.168.5.0 - 192.168.5.255 port-range 0 - 65535 protocol 0
-
-ikev2 profile set pr1 responder host-gw 192.168.10.1
-ikev2 profile set pr1 ike-crypto-alg aes-gcm-16 256 ike-dh modp-2048
-ikev2 profile set pr1 esp-crypto-alg aes-gcm-16 256
-
-create ipip tunnel src 192.168.10.2 dst 192.168.10.1
-ikev2 profile set pr1 tunnel ipip0
-ip route add 192.168.5.0/24 via 192.168.10.1 ipip0
-set interface unnumbered ipip0 use host-gw
-```
-
-Initiate the IKEv2 connection:
-
-```
-vpp# ikev2 initiate sa-init pr1
-```
-
-```
-vpp# show ikev2 sa details
- iip 192.168.10.2 ispi f717b0cbd17e27c3 rip 192.168.10.1 rspi e9b7af7fc9b13361

-```
-
-Now we can generate some traffic between responder's and initiator's private networks and see it works.
-
-```
-$ sudo ip netns exec ns ping 192.168.5.2
