Hi, all,

I have a network topology as the following:

1. Two Cisco 2800 routers,
2. A private line between these two routers,
3. they are running EIGRP
4. Each Router has ASA Firewall and the firewall connecting to the
internet through a broadband
5. A site-to-site VPN is built up between these two firewalls
6. How I configure the Routers and Firewalls in order to form a redunt
WAN network ?

Thanks so much in advance

If that is all you have, all you need to do is set the default gateway on
both 2800 to point to the ASA's. If the link goes down, the EIGRP route
will go away and all traffic will go to the ASA on each end. The ASA will
tunnel the traffec based on the crypto policy. It should be that simple.
Cheers.
