Has anyone ran across this error message: %CRYPTO-6-IKMP_MODE_FAILURE: Processing of Informational mode failed with peer at x.x.x.x? I've seen similar ones, but not the 'informational' mode. I'm also getting this message; ISAKMP (1): sending packet to x.x.x.x (I) MM_NO_STATE.
Any help would be great.
How did you fix it? I´m getting the same error on a Dual Hub Single Layout DMVPN even if I copy paste the same crypto info in all my hubs and spokes.
HI , please help me out with the solution. I am working on an office project and implemented cluster dmvpn. Though the tunnel is up, i keep getting this message.
As others have mentioned, double check that your keys and transform sets are matching on both ends.
During after hours try running debug crypto ipsec
