Remote office with a local Internet connection, but failover through the corporate network.And for home (/homeworker) networks ... eg I have a NAT box with a default connection to my ADSL provider and an automatic failover to 3G (completely separate supplier). Almost everything inside my network doesn't notice when it switches over. Now, if only I could get it to automatically revert to ADSL when it reappears - I wouldn't have to worry so much about the 3G bill. -- Roland Perry Nottingham, UK
In this case in IPv6, the better choice is to have addresses on each host from both providers. When a provider goes away, the router should invalidate the prefix in the RAs. If the hosts have proper address selection policies, they will actually go back to the ADSL prefix as soon as it reappears. Owen
