Implemented IKEv2 initiator features:
- IKE_SA_INIT and IKE_AUTH initial exchanges - Delete IKA SA - Rekey and delete Child SA - Child SAs lifetime policy To set up one VPP instance as the initiator use the following CLI commands (or API equivalents): ikev2 profile set <id> responder <interface> <addr> ikev2 profile set <id> ike-crypto-alg <crypto alg> <key size> ike-integ-alg <integ alg> ike-dh <dh type> ikev2 profile set <id> esp-crypto-alg <crypto alg> <key size> esp-integ-alg <integ alg> esp-dh <dh type> ikev2 profile set <id> sa-lifetime <seconds> <jitter> <handover> <max bytes> and finally ikev2 initiate sa-init <profile id> to initiate the IKE_SA_INIT exchange Child SA re-keying process: 1. Child SA expires 2. A new Child SA is created using the Child SA rekey exchange 3. For a set time both SAs are alive 4. After the set time interval expires old SA is deleted Any additional settings will not be carried over (i.e. settings of the ipsec<x> interface associated with the Child SA) CLI API additions: ikev2 profile set <id> responder <interface> <addr> ikev2 profile set <id> ike-crypto-alg <crypto alg> <key size> ike-integ-alg <integ alg> ike-dh <dh type> ikev2 profile set <id> esp-crypto-alg <crypto alg> <key size> esp-integ-alg <integ alg> esp-dh <dh type> ikev2 profile set <id> sa-lifetime <seconds> <jitter> <handover> <max bytes> ikev2 initiate sa-init <profile id> ikev2 initiate del-child-sa <child sa ispi> ikev2 initiate del-sa <sa ispi> ikev2 initiate rekey-child-sa <profile id> <child sa ispi> Sample configurations: Responder: ikev2 profile add pr1 ikev2 profile set pr1 auth shared-key-mic string Vpp123 ikev2 profile set pr1 id local fqdn vpp.home.responder ikev2 profile set pr1 id remote fqdn vpp.home.initiator ikev2 profile set pr1 traffic-selector remote ip-range 192.168.125.0 - 192.168.125.255 port-range 0 - 65535 protocol 0 ikev2 profile set pr1 traffic-selector local ip-range 192.168.124.0 - 192.168.124.255 port-range 0 - 65535 protocol 0 Initiator: ikev2 profile add pr1 ikev2 profile set pr1 auth shared-key-mic string Vpp123 ikev2 profile set pr1 id local fqdn vpp.home.initiator ikev2 profile set pr1 id remote fqdn vpp.home.responder ikev2 profile set pr1 traffic-selector local ip-range 192.168.125.0 - 192.168.125.255 port-range 0 - 65535 protocol 0 ikev2 profile set pr1 traffic-selector remote ip-range 192.168.124.0 - 192.168.124.255 port-range 0 - 65535 protocol 0 ikev2 profile set pr1 responder TenGigabitEthernet3/0/1 192.168.40.20 ikev2 profile set pr1 ike-crypto-alg aes-cbc 192 ike-integ-alg sha1-96 ike-dh modp-2048 ikev2 profile set pr1 esp-crypto-alg aes-cbc 192 esp-integ-alg sha1-96 esp-dh ecp-256 ikev2 profile set pr1 sa-lifetime 3600 10 5 0 Change-Id: I1db9084dc787129ea61298223fb7585a6f7eaf9e Signed-off-by: Radu Nicolau <radu.nicolau@intel.com>
