I would like to know if it is possible to bond different types of interfaces on CIsco routers to achieve increased bandwidth. I have bonded two t1 interfaces to achieve 3mbs throughput. Is it possible to bond or multilink a T1 interface, and one or more IP interfaces that may be connected to a high speed cable modem, to achieve higher throughput between our main office and a remote office. For example we can obtain a 50 mbs down 20 mbs up cable modem link to the internet at our main office. We can obtain 2 5mbs cable modem connections at our branch office. Can we aggregate these connections in our CIsco 2800 routers and create a single point to point VPN connection with 10mbs. I know we can purchase a device like a Pep Link but if the Cisco routers can do it I will use them.
