New Cisco 9300X IOS-XE Version 17.13.01 : IKEv2 Tunnel doesn't work

Steve Adams
Level 1
Level 1

REFERENCE: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9300/software/release/17-13/configuration_guide/sec/b_1713_sec_9300_cg/configuring_ipsec.html

I can get IKEv1 working no problem, but I cannot get IKEv2 working at all.

Configuration: (Similar to the LINK Above)

NOTE: Devices connected to a NXOS switch with INNER-VLAN routing
NOTE: Device 3 can ping the gateway 10.0.3.10 and 10.0.4.4
NOTE: Device 4 can ping the gateway 10.0.4.10 and 10.0.3.3
NOTE: GRE Tunnel comes up when 'tunnel mode ipsec ipv4' and 'tunnel protection ipsec profile IPSEC-IKEv2' are removed.
NOTE: I can get DMVPN configuration to work with 9300X's only, but not any other Cisco product: like a 4351/K9 router. (IKEv1 Only)

I can get IKEv1 working no problem, but I cannot get IKEv2 working at all.
I have tried different 'ikev2 proposal' and 'crypto ipsec transform-set' and nothing seems to work.
According to the link above, should it work?
Is the Cisco 9300X Version 17.13.1 broken or this not intended to work with IKEv2?

Is there an IKEv2 tunnel configuration that should work on the 9300X -to- 9300X ?

Hello MHM Cisco World,

I worked with a Cisco TAC, and I was able to get IKEv2 working with these changes:

crypto ikev2 profile IKEv2-Profile
 match identity remote address 0.0.0.0
 authentication remote pre-share
 authentication local pre-share
 keyring local IKEv2_KEYRING

@Steve Adams what the the IKEv2 Profile configuration of device 3? The IKEv2 profile was not matched against the peer's identity and authentication failed.

Hello Rob,

Thanks for your reply!

The config has been cut/paste directly into the post: Both Device-3 & Device-4 configurations are identical except ip addresses in the policy config. I have seen other similar posts with the error "peer matches *none" of the profiles", but never saw a resolution to those cases. I would like to think I am missing something in my config, but I posted the entire configuration. Am I missing something?

crypto ikev2 profile IKEv2-Profile
match fvrf any
match address local interface TenGigabitEthernet1/0/48
match identity remote any
authentication remote pre-share
authentication local pre-share
keyring local IKEv2_KEYRING

Share this debug

Hello MHM Cisco World,

Thanks for your response!

I have attached the debug output for 'debug crypto ikev2 packet'

Can you share both router config 

Tunnel

Ikev2 proposal 

Ikev2 keyring 

Ikev2 policy 

Ikev2 profile 

Ipsec profile 

Let me run lab and test this config in my side' your original post is OK but I need to see exact config in both routers

MHM

Hello MHM Cisco World,

Thanks for the quick replies, I have attached the isolated configurations I have for each device.

On the switch that I have these connected to, I am doing SIMPLE INNER-VLAN routing with VLAN interfaces as the gateways. Since I can ping everything, I left that part out. If you need a diagram, I can draft one up fast.
