New here? The first CHILD_SA is created for the proxy_ID pair that matches the trigger packet. Hi, made some more tests and my problem is the following, IPSec tunnel can be established if remote end is configured without any specific encryption domains for the communication and with a transport network within the tunnel (for routing purpose - like in GRE Tunnel). BR12-1X(config)# crypto ikev2 profile apple, BR12-1X(config-ikev2-profile)# config-exchange request, BR12-1X(config-ikev2-profile)# no config-exchange request.

Responder initiates SA creation for that peer. #address 10.0.0.2. I think i have the problem with the Source Interface (i receive"IKEv2-ERROR:Address type not supported" in log). This exchange consists of a single request/response pair and was referred to as a phase 2 exchange in IKEv1. Beginner. Cisco recommends that you have knowledge of the packet exchange for IKEv2. I shared this with TAC too. You cannot use PSK for authentication of a Remote Access FlexVPN, see this screenshot below from Cisco live presentation BRKSEX-2881. The sample configuration connects a Cisco ASA device to an Azure route-based VPN gateway. The IKE_AUTH packet contains: ISAKMP Header(SPI/ version/flags), IDi(initiator's identity), AUTH payload, SAi2(initiates the SA-similar to the phase 2 transform set exchange in IKEv1), and TSi and TSr (Initiator and Responder Traffic selectors): They contain the source and destination address of the initiator and responder respectively for forwarding/receiving encrypted traffic. You can only use PSK when the client is another FlexVPN hardware (router) client or Strongswan. Remote Type = 0. . Any luck getting this to work? Be aware the static route will only be withdrawn from the routing table if the Tunnel goes down. Zscaler support IP-SLA HTTP probes to check the cloud proxy health, on traditional routers you are able to use 'track' features to, for example, change the admin distance of a static route based on the results of the IP-SLA test. N(Notify payload-optional). You can also check the output of theshow crypto sessioncommand on both routers; this output shows the tunnel session status as UP-ACTIVE. For a branch office VPN that uses IKEv1, the Phase 1 exchange can use Main Mode or Aggressive Mode. The CLI based workaround for it (on cEdge).

This is the CREATE_CHILD_SA request. Learn more about how Cisco is using Inclusive Language. The keys used for the encryption and integrity protection are derived from SKEYID and are known as: SK_e (encryption), SK_a (authentication), SK_d is derived and used for derivation of further keying material for CHILD_SAs, and a separate SK_e and SK_a is computed for each direction.

If it guesses wrong, the CREATE_CHILD_SA exchange fails, and it will have to retry with a different KEi. 08-08-2018 My template for 'VPN Interface IPsec' looks like this: Then, this template is added under the Service VPN : I thought it was all working fine, however I now have a new problem.IKEv2 is working for Phase 1, but IPSEC is failing.For some reason the ISR4K is creating 16 SA's whilst Zscaler only support a maximum of 8 SA's, therefore the tunnel is currently unusable. The VPN is not connecting at all. All traffic must be accepted and specific routing is needed to direct traffic into specific tunnels. *Nov 11 19:30:34.841: IKEv2:Adding ident handle 0x80000002 associated with SPI 0x9506D414 for session 8 *Nov 11 19:30:34.841: IKEv2:(SA ID = 1):SM Trace-> SA: I_SPI=F074D8BBD5A59F0B R_SPI=F94020DD8CB4B9C4 (I) MsgID = 00000001 CurState: AUTH_DONE Event: EV_OK_RECD_LOAD_IPSEC *Nov 11 19:30:34.841: IKEv2:(SA ID = 1):Action: Action_Null *Nov 11 19:30:34.841: IKEv2:(SA ID = 1):SM Trace-> SA: I_SPI=F074D8BBD5A59F0B R_SPI=F94020DD8CB4B9C4 (I) MsgID = 00000001 CurState: AUTH_DONE Event: EV_START_ACCT *Nov 11 19:30:34.841: IKEv2:(SA ID = 1):Accounting not required *Nov 11 19:30:34.841: IKEv2:(SA ID = 1):SM Trace-> SA: I_SPI=F074D8BBD5A59F0B R_SPI=F94020DD8CB4B9C4 (I) MsgID = 00000001 CurState: AUTH_DONE Event: EV_CHECK_DUPE *Nov 11 19:30:34.841: IKEv2:(SA ID = 1):SM Trace-> SA: I_SPI=F074D8BBD5A59F0B R_SPI=F94020DD8CB4B9C4 (I) MsgID = 00000001 CurState:AUTH_DONEEvent: EV_CHK4_ROLE, *Nov 11 19:30:34.841: IKEv2:(SA ID = 1):SM Trace-> SA: I_SPI=F074D8BBD5A59F0B R_SPI=F94020DD8CB4B9C4 (I) MsgID = 00000001 CurState:READYEvent: EV_CHK_IKE_ONLY *Nov 11 19:30:34.841: IKEv2:(SA ID = 1):SM Trace-> SA: I_SPI=F074D8BBD5A59F0B R_SPI=F94020DD8CB4B9C4 (I) MsgID = 00000001 CurState: READY Event: EV_I_OK, *Nov 11 19:30:34.840: IKEv2:(SA ID = 1):SM Trace-> SA: I_SPI=F074D8BBD5A59F0B R_SPI=F94020DD8CB4B9C4 (R) MsgID = 00000001 CurState:READYEvent: EV_R_OK *Nov 11 19:30:34.840: IKEv2:(SA ID = 1):SM Trace-> SA: I_SPI=F074D8BBD5A59F0B R_SPI=F94020DD8CB4B9C4 (R) MsgID = 00000001 CurState: READY Event: EV_NO_EVENT. Create VPN Gateway Policy (Phase1) To create a Phase1 VPN policy, go to Configuration -> VPN -> IPSec VPN and click on the " VPN Gateway " tab. Client Related Configuration Same in every possible way. Source Interface in my setup is the WAN Interface connected to the Internet. The sample requires that ASA devices use the IKEv2 policy with access-list-based configurations, not VTI-based. cEdge supports standard IKE tunnels in 19.x. Initiator receives response from Responder. IKEv2-ERROR:Address type 1622425149 not supported My assumption is that although the IPSEC is created on the service side, by sourcing the tunnel from the interface with a public IP address in VPN0, the cEdge would VRF jump to VPN0. Use the VPN Interface IPsec feature template to configure IPsec tunnels on Cisco IOS XE service VPNs that are being used for Internet Key Exchange (IKE) sessions. this is due to 4.9 a lot of hash/cryptography where removed! Palo Alto IP: 1.1.1.1 Cisco ASA IP: 2.2.2.2 Cisco ASA iKev2 and IPsec parameters: Help would really be appreciated.

Has anyone been able to do this on a ISR4k? To a remote end configured with encryption domains i wasnt sucessfull. With IKEv1, you see a different behavior, because Child SA creation happens during Quick Mode, and the CREATE_CHILD_SA message has a provision to carry the Key Exchange payload that specifies the DH parameters to derive a new shared secret.
