I have a VPN setup between 851 and 7301 router and all of a sudden it is not working. No changes have been made to the network, I tried to clear the crypto on both ends even rebooted the remote router and still nothing. I did however notice that when I reboot the 851 router I get an error message towards the end "configuration failed" and then I can log into it.
Any chance that there might be an issue with the router because all I am getting is "MM_NO_STATE" on both ends when I do "show crypto isakmp sa"
