Has anyone here successfully get Site-2-Site VPN between a Cisco IOS router and PaloAlto working with IKEv2? When configuring the tunnel-group for a IKEV2 connection on a Cisco ASA, you need to specify a local and remote pre-shared key and these need to match on both sides. Hi Friends, Please checkout my new video on Site to Site ikev2 VPN with certificate between routers .

IKEv2 is a new design protocol doing the same objective of IKEv1 which protect user traffic using IPSec.IKEv2 provides a number of benefits over IKEv1, such as IKEV2 uses less bandwidth and supports EAP authentication where IKEv1 does not.IKEv2 support three authentication methods : 1. Conditional debug is very useful to filter out some of the debug information that you see on a (busy) router. PaloAlso support stated that Cisco sent them the wrong data but the cisco TAC engineer had no clue. Peer 40.10.1.1:500 Id: 40.10.1.1, Crypto logging ezvpn, introduced in 12.4(4)T, displays EasyVPN connection messages, %CRYPTO-5-SESSION_STATUS: Crypto tunnel is DOWN. IKEv2 must be configured on the source and destination router (peers) and both routers must employ the same authentication method. 11-04-2020 This is the wrong policy, it should be '127' but the fvrf is 0, and the local address will always be 192.168.1.2, this is because the ASA address attached to the router is where the incoming connection for the vpn is PASSING THROUGH, not coming from. 11-04-2020 Whatever IP address I try in debug condition ipnothing shows up Im guessing that this command doesnt work for most debug commands. Cisco TAC support is not very helpful. After going back and forth with him, I essentially give up. But thank you. The only thing I see on the output you posted that doesn't look right is the keyring PaloAlto command under the crypto ikev2 profile, that should read keyring local PaloAlto, but I think that is simply a typo. crypto ikev2 profile PaloAltomatch identity remote address 1.1.1.1 255.255.255.255authentication local pre-shareauthentication remote pre-sharekeyring PaloAlto, crypto ipsec transform-set PaloAlto esp-aes 256 esp-sha-hmac!crypto map vpn 10 ipsec-isakmpset peer 1.1.1.1set transform-set PaloAltoset pfs group20set ikev2-profile PaloAltomatch address PaloAlto, permit ip host 192.168.1.1 192.168.246.0 0.0.0.255permit ip host 192.168.1.2 192.168.246.0 0.0.0.255, interface GigabitEthernet0/0ip address 4.2.2.251 255.255.255.248duplex autospeed autocrypto map vpn, Platform is Cisco 2921 running version c2900-universalk9-mz.SPA.151-4.M10.bin, 10-30-2020 Many thanks. IKEv1 phase 2 negotiation aims to set up the IPSec SA for data transmission. On the router use the command debug crypto ikev2, and on the Palo Alto use: debug ike gateway on, debug ike tunnel on. This is the IKE/IPSec config I'm using on the hubs (which I copied from a website). IKEv2 Authentication The Cisco CG-OS router employs IKEv2 to authenticate to the destination router by using either a pre-shared key (PSK) or by using RSA signatures with a Public Key Infrastructure (PKI). Correlation Peer Index = 0. Here we go: The configuration is very straight forward, nothing mystery about it. DMVPN is a cisco "only" solution and has nothing to do with my situation here. IKEv2:% Getting pre-shared key from profile keyring IKEv2_KEYRING IKEv2:% key not found. 11:28 AM IKEv2 is the supporting protocol for IP Security Protocol (IPsec) and is used for performing mutual authentication and establishing and maintaining security associations (SAs). and one captured during the IPsec initialization: However the Palo Alto appears to give just pre-shared key box So my assumption would be that on the Cisco you would make the local and remote ikev2 PSK's exactly the same. New here? This document describes Internet Key Exchange version 2 (IKEv2) debugs on Cisco IOS when a pre-shared key (PSK) is used. Correlation Peer Index = 0. Conditional Debug on Cisco IOS Router. If you've already registered, sign in. Local Type = 0. what do you see in output fromsh crypto isakmp sa? Thanks. This output shows an example of the debug crypto ipsec command. On Palo Alto repeat those debug commands replacing on with off. Remote Address = 0.0.0.0. Correlation Peer Index = 0. The TAC engineer from Cisco was pretty much useless. Being in VPN technology we explain this to many of our customers and thought of discussing it here on our support forum as well.

The thing is that if I replace the Cisco IOS router with an ASA device with the same EXACT configurationi, VPN IKEv2 will work fine between ASA and PaloAlto so I know the configuration on the PaloAlto is good. Questo scambio costituito da una singola coppia richiesta/risposta ed stato definito come scambio di fase 2 in IKEv1. It's best to demonstrate this with an example, so let me show you the .
