Im setting up a s2s vpn between a Palo and a Cisco ASR. The GUI is showing it all as up - green lights and ike tunnels. But the logs are showing the below:
IKEv2 child SA negotiation is failed message lacks KE payload
I am not sending traffic down the vpn yet so i am unable to ascertain if this is important message or not (would rather know it works before i tell my boss it is working!)
Solved! Go to Solution.
Got to the bottom of this. The Cisco was actually using a route-based VPN. I had been expecting a policy-based VPN so had configured Proxy-ID's on the Palo Alto.
I have removed the Proxy-ID's from the config and the tunnel; has stayed up but the log errors have stopped
