IKEv2 SA drops immediately

[rolfd]

Hello,

I want to set up a IPSec IKEv2 VPN to a central ASA. On my side we have a cisco 897.

First I tried a crypto map configuration. Didn't work because the IKEv2 SA goes UP and immediately goes DOWN with the error message "IKEv2:(SESSION ID = 1,SA ID = 1):Queuing IKE SA delete request reason: unknown".

Afterwards I tried a VTI configuration, but the IKEv2 SA was dropped immediately with the same error.

Below you find my configuration:

Does anybody has an idea, why the ikev2 sa will be dropped?

Many thanks in advance for support.

Tunnel source and tunnel ip unnumbered use same interface' can you add IP to tunnel instead of use unnumbered

[MHM Cisco World]

Why you use tunnel IP same as G0 IP sunbet?

You need to use different subnet for tunnel IP

Also the crypto ipsec transform have esp-null ? Why that ?

MHM

[rolfd]

193.29.25.33/28 is different to 193.29.25.88/28

I changed already esp-null to

crypto ipsec transform-set ESP-AES-SHA esp-aes 256 esp-sha-hmac

but no change. I have to stop for today and will start again tommorow.

Many thanks for your support today.

I changed also the access-list, because on the ASA the net 193.29.25.32/28 are routed into the tunnel.

access-list 101 permit ip 193.29.25.32 0.0.0.15 192.168.0.0 0.0.255.255

I did som investigations via

debug crypro ikev2
debug crypro ikev2 internal
debug crypro ikev2 paket

and I see the foolwing messages:

From my understanding the transform set is the problem, because it offer AES-CBC SHA96. This would not be accepted from the ASA, so I got no proposal chosen.  I changed several times the transform set, but I see every time the above message.

Could it be a problem with the IOS release 15.5? I do not have any idea to go further.

Sorry for late reply 

Can you share both IOS and ASA config
