We have about 8 Cisco 1801s deployed using broadband and the ezvpn client configuration back to head office. One of our sites keeps experiencing intermittent dropouts of its ADSL interface which we are investigating. However the problem is compounded because when the atm interface comes back up the ipsec tunnel does not. I have to log on to the public address of the router and issue the 'clear crypto ipsec client ezvpn' command. Below is samples of the relevant configuration. Is there a way to force the tunnel to clear down and reconnect if the atm changes state?
Yes, you can force the tunnel to clear down and reconnect if the atm changes state.To specify automatic tunnel control on a Cisco Easy VPN remote device, you need to configure the "crypto ipsec client ezvpn" command and then the "connect auto" subcommand.To disconnect or reset a particular tunnel, you should use the clear crypto ipsec client ezvpn command.
