Hi,
I have a network topology as the following:
- Two Cisco 2800 routers,
- A private line between these two routers, and they are running EIGRP
- Each Router has ASA Firewall and the firewall connecting to the internet through a broadband line
- A site-to-site VPN is built up between these two firewalls
- How can I know if the site-to-site VPN tunnel is working if no traffic goes through it, since it is the backup link for the private line ? Is tunnel self fire to keep the site-to-site up ?
Thanks so much in advance
