About This Solution
This lab presents troubleshooting techniques that can be used when working with LAN-to-LAN IPsec VPN connections on ASA and IOS devices. These techniques come directly from service requests that the Cisco Technical Support have solved. Many of these methods can be implemented prior to an in-depth troubleshooting of an IPsec VPN connection. As a result, this lab session provides a checklist of common procedures to be followed in order to troubleshoot an IPSec VPN connection before you reach out to the Cisco TAC.
Prerequisites
Knowledge of IPsec based VPN Technologies
Basic experience in troubleshooting of IOS and ASA devices.
