Remote site 2 Internet Connections...

[bjgodfrey]

I have a remote office that currently connects back to a Central data center via Site to Site VPN.  I am bringing up a 2nd internet connection as a fall back in the Remote Office.  How do I configure the Site to Site VPN to work correctly so that if the primary internet connection goes down, the site fails over to the secondary? 

On Remote the internet connections are from different providers so they have completely different blocks of public IPs.

Central

ASA 5520 8.0(4) 

Gig 0/0 Public IP

Remote

ASA 5520 8.4(1)

Gig 0/0 Public IP

Gig 0/3 Public IP (2nd internet)

On the HQ end you need to enter the new ISP (for remote site) IP address as secondary peer.

On Remote end you need to add SLA so that traffic will be redirected over second link incase of primary failures.

Search the forum you find many  posting with ref to this scenario. Here is one...
