I have a client that has the following setup. &nbsp;A T1 as the primary Internet connection terminated by the providers Adtran router and a DSL connection terminated by a DSL modem. &nbsp;They want to stick the Cisco 2620 with a 4port Eth card in the middle to control routing and failover. &nbsp;Will this work? &nbsp;Routing is not a problem but the failover I think is. &nbsp;If you just use simple route statements with a higher distance metric for the DSL it would normally work but the problem is that If the WAN side of the T1 Adtran router goes out, the Eth interface on the Cisco will still appear up thus not change the route to the DSL. &nbsp;Is there any way to get this to work without the Cisco router controlling the WAN side too?

How to configure Cisco 2620 for failover between T1 and DSL

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
