Hi there,

Hi there,

It seems, its down to the tunnel protection command under tunnel interface 

IKE Profile Based Tunnel Selection

The IKE Profile Based Tunnel Selection feature uses the Internet Key Exchange (IKE) or Internet Key Exchange version 2 (IKEv2) profile to select a tunnel interface for an IPsec session. Use keywords isakmp-profile or ikev2-profile keyword in the tunnel protection command to specify an IKE profile or IKEv2 profile respectively.

o associate a tunnel interface with an IP Security (IPsec) profile, use the tunnel protection command in interface configuration mode. To disassociate a tunnel with an IPsec profile, use the no form of this command.

tunnel protection ipsec profile name [shared | { isakmp-profile | ikev2-profile } name]

Please try adding ikev2-profile with tunnel protection and check.

Also check your IOS version should be greater 15.2 i assume.

Legend! I had the match fvrf command in the ikev2 policy, but in the profile. Have added that and now it is working, thank you so much.
