I must admit I am a Cisco neophyte and i am trying to configure a 1841 router to support 3 WAN connections. One is a 20mb/s fiber connection, the other two are T1's.
I would like to configure the 20mb/s connection as my primary while the combined T1's would serve as a backup.
I can easily get each one of the connections to function properly, but I don't know how to start on configuring the T1's as backup.
Any hint on how to get started would be greatly appreciated.
