I've setup VPN links on older 1921 routers before using the auto-generated scripts but this 2901 is throwing the following errors:
crypto ikev2 proposal azure-proposal^

2840 bytes copied in 0.108 secs (26296 bytes/sec)
The only difference I can think of is that this router is running IOS 15.4 and in Azure's documentation, it says definitively "15.1". Does this mean that I have to downgrade the router firmware or am I missing something else?
